W hat we eat and where it comes from matters. [FN2] While over the past few decades animal activists have been advocating for the humane treatment of animals, [FN3] the battle over farm animal welfare recently made its way onto the November 2008 California state ballot, [FN4] in the form of Proposition 2 (“Prop 2”), [FN5] the Prevention of Farm Animal Cruelty Act. [FN6] This Act, while arguably “modest,” [FN7] will prospectively improve living standards for farm animals by prohibiting conditions that do not allow animals to lie down, stand up, fully extend their limbs, or to turn around, [FN8] thus banning in California three widely used agricultural *266 confinement systems: [FN9] the battery cage for egg-laying hens, [FN10] the veal crate for baby male cows, [FN11] and the gestation crate for pregnant pigs. [FN12] Due to the nature of California's agricultural industry, this Act prompted a fight between the egg industry and Prop 2 supporters. [FN13] According to the agricultural trade magazine Egg Industry , [FN14] animal activists' efforts to bring Prop 2 to the California ballot was not something to be taken lightly; United Egg Producers (“UEP”) [FN15] stated that it needed “all hands on deck” for what the magazine deemed possibly “one of the biggest and most important battles of U.S. egg industry history.” [FN16] UEP was justified in its concern: on November 4, 2008 animal rights advocates around the U.S. celebrated [FN17] at the expense of agribusiness as Prop 2 passed by *267 63.2%, [FN18] thus securing more humane treatment for farm animals raised in California. [FN19]

The current American “farm” house, with thousands of animals in a large-scale, factory-type [FN20] setting, is a relatively recent phenomenon. [FN21] Although the U.S. Congress enacted the federal Animal Welfare Act [FN22] in 1966 to provide federal protection for animals, [FN23] it contains a specific exemption for farm animals. [FN24] Thus, states retain the responsibility of protecting farm animals. [FN25] Until the recent passing of Prop 2 [FN26] and similar *268 statutes, [FN27] anti-cruelty statutes were the sole means of protection for farmed animals, but they were extremely ineffective due to exemptions for “customary” farming practices, [FN28] such as battery cage housing for hens. [FN29] While similar laws previously passed in Florida, [FN30] Arizona, [FN31] Oregon, [FN32] and Colorado, [FN33] Prop 2 [FN34] is the first to create minimum farm animal welfare standards for battery cage hens, and thus, is groundbreaking. [FN35] In fact, Feedstuffs , deemed “one of the largest agribusiness *269 newspapers in the country,” [FN36] states that Prop 2 will affect the production of livestock and poultry throughout the U.S., and possibly all of North America. [FN37] Since its passing, Maine and Michigan passed similar laws, and Ohio negotiated an agreement between animal advocacy organizations, members of the agriculture industry, and its governor, to change industry practices. [FN38] Laws are also pending before other state legislatures. [FN39] Furthermore, the Humane Society of the United States (“HSUS”) announced a push for federal legislation prohibiting federal programs from contracting with suppliers who raise animals used for meat, egg, and dairy products, in conditions of extreme confinement. [FN40]

However, it is still unclear how far these humane treatment laws will extend. For example, some farms contest what standards are deemed acceptable by Prop 2's requirements; [FN41] others speculate that, due to necessary cost-prohibitive renovations, they will have to “downsize or *270 close.” [FN42] Furthermore, the new laws for gestation and veal crates currently only apply to in-state agricultural producers, while the law regarding eggs was recently extended to prospectively cover the production methods of all whole eggs sold in California (regardless of the state where they were originally produced). [FN43] The strong public support for Prop 2 [FN44] begs the question--how much longer will American consumers continue to accept the production of eggs raised in intensive confinement systems? [FN45]

Arguably one of the most significant implications of the increase in humane farming legislation in the U.S. is the potential impact on international trade. The U.S. has certain international treaty obligations that it must uphold when trading with other countries: [FN46] these commitments can be found in the General Agreement on Tariffs and Trade [FN47] (“GATT”), which is the World Trade Organization's (“WTO”) [FN48] agreement to reduce *271 trade barriers for goods. [FN49] According to the Vienna Convention, [FN50] which contains rules governing treaty enforcement, [FN51] treaties must be “interpreted in good faith in accordance with the ordinary meaning to be given to the terms of the treaty in their context and in light of its object and purpose.” [FN52] Furthermore, “[s]ince clarity and predictability are goals of the dispute settlement system, [FN53] WTO [dispute settlement] Panels have consistently said that the Vienna Convention is the tool they use to interpret the GATT.” [FN54]

Importantly, the GATT's goal of reducing trade barriers through its various provisions, as interpreted by the Vienna Convention, could conflict with potential new animal welfare standards that lay out new expectations for both domestic and foreign producers. However, the fact that the U.S. and other countries are beginning to recognize and promote animal welfare standards, [FN55] suggests that as countries begin to modify their own measures at home, they will demand similar measures from their trading partners as well. [FN56] In turn, this may place pressure on the WTO to *272 accept animal welfare standards as complying with GATT trading obligations. Further, this trend suggests that animal welfare may begin to play a role in determining trade rules between countries, or at the very least, may begin to have a presence amidst trade discussions, concerns, and objectives. [FN57] However, when analyzing a dispute between nations, it is still unclear if a WTO dispute settlement panel would see a trade restriction such as a countrywide ban on the production and importation of battery cage eggs, as a violation of WTO obligations. The WTO should accept and recognize such a restriction as complying with the GATT, due to the fact that the purpose of such a measure coincides with the plain meaning and purpose of certain GATT provisions.

Part I of this Note analyzes the U.S.'s trade obligations under the GATT. Part II discusses the potential ability of various GATT provisions to support a trade measure banning battery cage eggs. Part III discusses the U.S.'s potential ability to create such an animal welfare provision. while upholding its obligations in the Agreements annexed to the GATT. The Note concludes that an appropriately tailored animal welfare measure banning battery cages for hens should be able to survive under the GATT and its annexed agreements.


While seemingly removed from farm animal welfare issues, trade agreements have the ability to bring about significant animal welfare reform in the agricultural industry. [FN58] Currently, the WTO can be seen as both a friend and a foe to initiatives seeking to improve animal welfare in *273 farming practices. [FN59] The GATT contains many obligations for member countries that restrict the way that products can be differentiated. For example, under Article I(1), [FN60] the Most-Favored Nation (“MFN”) clause, and Article III(1), [FN61] the National Treatment clause, a WTO member cannot treat “like” products [FN62] from other WTO member countries less favorably than the same products from any other country, [FN63] or less favorably than its own domestic products. [FN64] These obligations limit WTO members' abilities to create trade restrictions on battery cage eggs.

Article I's MFN principle mandates that “any advantage, favour, privilege or immunity” granted by a WTO member to another country's product “shall be accorded immediately and unconditionally” by that WTO member to any other WTO member's like product. [FN65] In essence, instead of permitting one country to bestow special treatment on another country, MFN requires equal treatment for all WTO members. [FN66] Article III contains the National Treatment principle, which mandates that internal charges cannot be applied in a way “so as to afford protection to domestic production.” [FN67] It is important to emphasize that in both MFN and National Treatment, the principles only prohibit discrimination against “like” products. [FN68] While at first glance, it may appear that the differing *274 manners in which products are produced (such as eggs from battery cages and eggs from cage-free facilities) change them so that they are not “like” one another, these differences are considered to be “processes and production methods” (“‘PPMs”), [FN69] which generally do not change a product's likeness to another product. [FN70]

In The World Trade Organisation Rules: A Legal Analysis of Their Adverse Impact on Animal Welfare , [FN71] Peter Stevenson cites two WTO Panel reports, the Tuna-Dolphin cases, [FN72] that demonstrate how the WTO has held that two commodities (in this case, tuna caught in seine nets, which cause high mortality rates amongst dolphins (“non-dolphin-safe nets”), and tuna caught in nets designed to reduce dolphin mortality rates (“dolphin-safe nets”)), are the same product, and cannot be distinguished from one another based on the way they are caught. [FN73] Specifically, the first Panel held that Article III requires “a comparison of the treatment of imported tuna as a product with that of domestic tuna as a product . Regulations governing the taking of dolphins incidental to the taking of tuna could not possibly affect tuna as a product.” [FN74] GATT Panel reports like those from the Tuna/Dolphin cases [FN75] articulate that a country cannot take into account the way that a product is produced when determining *275 if it is “like” another product, [FN76] because the production method does not change the end product. [FN77] Furthermore, whether or not a product is “like” another product is “fundamentally, a determination about the nature and extent of a competitive relationship between and among products.” [FN78] For example, tuna products caught in non-dolphin-safe nets are seen as directly competing in the marketplace with tuna products that are caught in dolphin-safe nets. Therefore, the WTO reasons that despite having different PPMs, these tuna products are “like” products. [FN79] In fact, no GATT Panel has thus far allowed a country to distinguish “like” products based on differing PPMs (with the exception of differing PPMs that can cause severe health risks). [FN80]

However, there is a strong argument that eggs produced by battery cage hens and eggs produced by cage-free hens undergo such vastly different production methods, that they should not be considered “like” products. [FN81] The analysis of whether two products are “like” one another is dependent--at least in part--upon consumer preferences, [FN82] since “consumers' tastes and habits are one of the key elements in the competitive relationship between products in the marketplace.” [FN83] Importantly, consumers who buy cage-free eggs do not see these two products as “like” one another, [FN84] since they make the conscious decision to buy one product based on its more “humane” production method. [FN85] Furthermore, if hens *276 are fed grass at pasture (as opposed to a seed diet in battery cages) they arguably produce a healthier egg. [FN86] Since consumers treat these two products (battery cage and cage-free eggs) differently, the WTO should follow suit. However, past Panel decisions have given no indication that future Panels will consider PPMs as affecting products' likeness to one another. [FN87]


Historically, the GATT treated measures made in pursuit of animal welfare goals unfavorably; [FN88] however, some GATT provisions actually indicate that such measures should be protected. [FN89] Even if a country's trade measure violates a trading obligation, such as MFN or National Treatment, it may be upheld as a permissible exception under GATT Article XX, [FN90] arguably one of the most important Articles in the GATT. [FN91] This exceptions provision allows, in “certain circumstances, legitimate public policy considerations other than trade liberalisation to take precedence *277 over the free trade requirements of the main GATT articles.” [FN92] When analyzing a country's trade measure under Article XX, the WTO must first look at the particular provision of the Article, to see if the measure appropriately fits under the provision's described exception; [FN93] then, the WTO analyzes the measure under the “chapeau” [FN94] of Article XX to ensure that the measure is not “arbitrary or unjustifiable discrimination ... or a disguised restriction on international trade.” [FN95] The chapeau is important for its role in helping to “rein in national abuse of the exceptions.” [FN96] There are three different provisions within Article XX that could potentially be used to protect an animal welfare measure from violating the GATT.

A. Article XX(g): Exception for Exhaustible Natural Resources

Article XX(g) is most likely the weakest of the three potential provisions to support a battery cage ban. This provision allows WTO members to enact measures applying to both foreign and domestic products, in order to conserve “exhaustible natural resources.” [FN97] However, it has been analyzed by GATT Panels and the Appellate Body in the Shrimp/Turtle cases [FN98] in a way that is favorable for only some animal welfare measures. [FN99] In Shrimp/Turtle I, the Panel recounts how the U.S. passed a regulation in 1987 [FN100] that required shrimp trawling fishermen to use certain methods to decrease turtle mortality caused by traditional shrimp *278 trawling. [FN101] In 1989, the U.S. passed Public Law 609. [FN102] which prohibited the importation of shrimp products that had been harvested with fishing technology that adversely affected sea turtles. [FN103] Malaysia, India, Pakistan, and Thailand challenged this law before the WTO, [FN104] and after an appeal, the Appellate Body found that the measure did not fit within any Article XX exception, due to the fact that it created “arbitrary or unjustified discrimination.” [FN105] Consequently, the U.S. changed its law to mandate shrimping in a manner that was “comparable in effectiveness” (but not exactly the same) as that of the U.S. [FN106] Malaysia again brought an action before the WTO in Shrimp/Turtle Malaysia I /, but the Panel and subsequent Appellate Body (Shrimp/Turtle Malaysia If) found the revised U.S. law to be non-discriminatory. [FN107] This holding significantly deviated from the previous cases in that it allowed the U.S. to restrict *279 trade based on the objective of protecting a natural resource, [FN108] albeit not in an unjustifiable or arbitrarily discriminatory manner. [FN109]

Some argue that the Shrimp/Turtle Malaysia II decision should extend to future cases and the WTO should “interpret any ambiguities in the regime in a way that is favourable to protecting the environment and/or animal welfare.” [FN110] The impact of Shrimp/Turtle Malaysia II should not be understated; it was the first time in GATT and WTO history that a “unilateral extraterritorial national measure was upheld on environmental grounds.” [FN111] The Shrimp/Turtle decisions demonstrate that a country can restrict or ban foreign products to conserve “exhaustible natural resources” [FN112] if the restriction is concurrent with similar domestic restrictions, [FN113] and indicates that a country may be able to exert some control over PPMs. [FN114]

However, the decision's usefulness in relation to a battery cage egg ban may be limited. A dispute settlement panel would be unlikely to extend the Shrimp/Turtle Malaysia II holding, which affected an endangered species, [FN115] to farm animals such as egg-laying hens that eventually *280 will be killed for food. [FN116] The fact that hens are nowhere near species exhaustion [FN117] suggests that a dispute settlement panel may not interpret this provision to protect an animal welfare measure for cage-free eggs. However, the “exhaustible natural resources” provision [FN118] applies to more than just endangered species. In fact, in compliance with the Vienna Convention's treaty interpretation method, according to the ordinary meaning of the treaty's words, [FN119] a farm animal like a hen can be considered a “natural resource.” [FN120] Furthermore, under XX(g), the measure does not need to be “necessary” for conserving the natural resource, as is the case for some other Article XX measures; [FN121] it must simply “relate to” conserving the natural resource. [FN122] In sum, XX(g) could still be an option, but other provisions may provide stronger support.

B. Article XX(b): Exceptions for Human, Animal, and Plant Health

Unlike Article XX(g), Article XX(b) may be more successfully used to uphold a trade measure differentiating between farm products that are produced more humanely than others. This provision allows WTO members to enact measures “necessary to protect ... animal ... health.” [FN123] It is unclear whether a dispute settlement panel would interpret a measure banning battery cages for hens (in order to protect their welfare) as related to animal health; “the argument that animal health includes animal *281 welfare ... has not yet been fully established or accepted.” [FN124] Additionally, previous GATT Panels have seen Article XX(b) as relating solely to “animal life and health” and not animal welfare. [FN125] This ambiguity, as to whether the WTO intended animal “health” to encompass animal “welfare,” could lead some critics to allege that this provision was not meant to protect the welfare of all animals. This sentiment is illustrated by the fact that some countries, like the U.S., have federal laws purporting to protect the welfare of all animals, but these laws specifically exempt farmed animals from their protection. [FN126] Traditionally, the WTO limits its recognition of animal health provisions to those regarding disease prevention and food product safety for humans. [FN127]

Additionally, it is unclear if a panel would interpret Article XX(b) as permitting Country A to enact a trade measure that would protect the welfare of hens in Country B (based on the idea that the eggs will eventually be imported into Country A). [FN128] In Tuna-Dolphin I, the Panel held *282 that Article XX(b) should be interpreted to allow a country to protect health only inside its own borders, because if a country was allowed to protect health outside of its borders, “each contracting party could unilaterally determine the life or health protection policies from which other contracting parties could not deviate without jeopardizing their rights under the General Agreement.” [FN129] Further, a measure protected by Article XX(b) must be deemed “necessary” [FN130] in order to be upheld--this is a difficult standard to meet, since “any number of hypothetical policies could fulfill a social objective without trade restrictions, even if such policies are unrealistic.” [FN131]

However, regardless of these problems, a future Panel should find that Article XX(b) can uphold a battery cage ban. While “‘[w]elfare’ is a broader term than ‘health,”’ [FN132] the International Office of Epizootics (“OIE”) [FN133] sets international standards for The Agreement on the Application of Sanitary and Phytosanitary Measures (“SPS Agreement”), [FN134] which is annexed to the GATT (and discussed in Part III of this Note), [FN135] and has deemed the terms to be interconnected. [FN136] As will be discussed, the connection between Article XX(b) and the SPS Agreement, [FN137] as well as the current enhancements being made to the SPS Agreement, strengthen the case that animal welfare is related to animal health (and thus an animal welfare measure should be protected by Article XX(b)). Additionally, research has been conducted to show that battery cages prohibit hens from engaging in their normal behaviors and cause them to *283 have health and psychological problems. [FN138] Also, based on the ordinary meaning of Article XX(b), there is no indication of an intention to only allow a country to protect animal health within its borders, [FN139] and throughout history, countries have enacted trade measures which have the effect of controlling production in other countries. [FN140] Finally, a battery cage ban is “necessary” to protect animal welfare, since the battery cage production method itself has a detrimental effect on hens. [FN141]

However, a dispute settlement panel may give great weight to the monetary burden that such a production change would place on another country, particularly a developing country. Two disputes brought before the Appellate Body, one using Article XX(b) successfully as a defense [FN142] and another using Article XX(g) successfully as a defense, [FN143] demonstrate *284 that the WTO will seriously consider the implications of a trade restriction on a developing country, even if it is otherwise appropriate under Article XX. In both cases, the Appellate Body considered the greater difficulty that developing countries may have in implementing animal welfare trade measures, but ultimately, concluded that the trade measures could succeed, as long as they were not too constrictive. [FN144]

With a battery cage ban, the alleged “costs” may not be as constrictive as critics assume. For example, developing countries may be better equipped to implement animal welfare standards than even some developed countries, due to the fact that more humane production methods are generally more “labor-intensive” [FN145] and developing countries tend to have cheaper labor costs than developed countries. [FN146] If the U.S. was to enact a trade measure that only sanctioned certain types of egg production for animal welfare-related reasons, it would need to acknowledge developing countries' abilities to implement and enforce such a measure. and consequently would need to be flexible due to these differing abilities. If the U.S. created a battery cage ban with these considerations in mind, Article XX(b) should be able to defend such a measure.

C. Article XX(u): The Public Morals Exception

Article XX(a). which allows WTO members to create measures “necessary to protect public morals,” [FN147] should also support a battery cage egg ban. While this provision has only been used on rare occasions, [FN148] trade restrictions in favor of more humane practices may be covered [FN149] as a result of society's views on the need to treat animals humanely. [FN150] In fact, *285 the public morals provision may soon be invoked with regard to two recent requests for WTO dispute settlement consultations launched by Canada and Norway (non-EU members) [FN151] against the EU for its ban on imported seal products, which began in August 2010. [FN152] Canada and Norway allege that the ban violates the EU's trade obligations under the WTO. [FN153] The EU defends its ban based on public outrage over the cruelty associated with seal slaughtering practices; [FN154] in his expert submission to the European Parliament's Committee on the Internal Market and Consumer Protection, Jacques Bourgeios said, “It is fairly easy to demonstrate that the inhumane killing and skinning of seals is a matter of [European] public morality.” [FN155] However, to meet XX(a)'s standards, the EU's ban must also be “necessary” to the protection of public morals and must meet the chapeau's requirements. [FN156] Humane Society International *286 (“HSI”) alleges that a total ban on seal products meets the “necessary” requirement because no alternative measures will produce the same desired effect. [FN157] that the ban meets the requirements of the chapeau since it applies to all seal products (and does not discriminate against one country's products over another's), and that it is not a disguised restriction on trade because it does not favor the EU's seal products over foreign products. [FN158]

However, the dispute settlement panel may also consider the costs such a trade measure will impose on countries like Canada and Norway. [FN159] As previously acknowledged, higher animal welfare standards typically translate into increased production costs. [FN160] In this case, the EU is not proposing an alternative method of seal slaughter so the costs are even more significant, since the countries selling seal products will no longer have access to the EU market. Thus, such a measure may be seen as a trade barrier [FN161] that directly conflicts with the WTO's overall mission to promote trade liberalization. [FN162] However, a dispute settlement panel *287 should ultimately view these costs, even in the case of a total elimination of a market, as less important than the fact that the animal welfare measure meets all of the requirements of Article XX(a), as it is a necessary measure for the protection of public morals that does not violate the chapeau.

If the seal product ban is successful in defeating a WTO violation claim, it should open the door to use Article XX(a) to defend other animal welfare-driven measures. [FN163] Seal slaughter may be considered “inherently cruel” [FN164] because of the weather conditions and its isolated nature, while farming conditions can be controlled and changed. However, it is difficult to see how the seal hunt's practices are any more inhumane than those common to intensive farming practices, such as battery cages. [FN165] Further, intensive confinement practices continue for the farm animals' entire lives; this fact could offend public morals even more than an abhorrent seal slaughter technique. According to 2003 survey data, 96% of Americans believe that animals should have “at least some protection from harm and exploitation” [FN166] and 62% of Americans support the passage of “strict laws concerning the treatment of farm animals.” [FN167] As shown by these statistics, conventional intensive farming techniques that cause severe harm to animals are offensive to the American public. Furthermore, *288 as previously discussed relevant to Article XX(b), [FN168] a total ban on battery cages would meet the “necessary” requirement of Article XX(a), [FN169] because the intensive production methods would need to be eliminated in order to reduce the harm to animal welfare. The ban would satisfy Article XX's chapeau, since it would apply to all battery cage eggs from all countries, including those within the U.S. Additionally, a battery cage ban would not be a total trade barrier for eggs, since battery cage eggs could be replaced by cage-free eggs. Based on all of these factors, a dispute settlement panel should deem a battery cage ban protected under Article XX(a).


Additionally, two Agreements annexed to the GATT should provide support for the legality of a trade measure such as a batten' cage ban. First, the SPS Agreement was created to give WTO members “the right to take sanitary and phytosanitary measures necessary for the protection of human, animal or plant life or health,” [FN170] and is meant to be an elaboration of certain GATT provisions, “in particular the provisions of Article XX(b).” [FN171] Second, the Agreement on Agriculture (“AoA”) [FN172] was created to “strengthen [] multilateral rules for trade in agricultural products and require[] WTO members to reduce protection against imports, trade-distorting domestic support programs, and export subsidies.” [FN173] It also allows countries to create “non-trade-distorting,” or Green Box, subsidies. [FN174] The SPS Agreement and the AoA should be used to defend animal *289 welfare trade measures and programs, [FN175] respectively, to incentivize the more humane treatment of farm animals.

A. The SPS Agreement and OIE International Standards

The SPS Agreement, especially when coupled with GATT Article XX(b), should provide protection for an animal welfare measure banning battery cages. Although the SPS Agreement applies to sanitary and phytosanitary measures to protect food safety or human, animal, or plant life or health, [FN176] the connections made between animal health and animal welfare [FN177] suggest that measures concerning animals who produce food products (such as egg-laying hens), are relevant under this Agreement. The SPS Agreement's “principal objective ... is to promote the harmonization of national standards;” [FN178] measures that “conform to international standards, guidelines, or recommendations” are automatically deemed “necessary” for the protection of human, animal or plant life. [FN179] In connection with this goal of harmonization, the OIE, which is seen as “the primary source of ... international health standards” on animal health issues, [FN180] is mandated by the SPS Agreement “to safeguard world trade by publishing health standards for international trade of animals and animal products.” [FN181] The OIE's Terrestrial Animal Health Code (“Terrestrial Code”) [FN182] contains a chapter with Animal Welfare provisions, [FN183] but *290 the chapter focuses on transporting animals by sea, [FN184] land, [FN185] or air; [FN186] slaughtering animals; [FN187] killing animals for controlling disease; [FN188] guidelines on how to control stray dog populations; [FN189] and guidelines for using animals for research or education purposes. [FN190] The Code references the importance of animal welfare by stating that humans who use animals have an “ethical responsibility” to ensure animal welfare “to the greatest extent practicable,” [FN191] and also that higher animal welfare can often improve food safety. [FN192]

While the OIE's current statements do not set international standards that easily translate to animal welfare measures, [FN193] there are signs that this may soon change. The OIE publicly vocalized its commitment to setting standards for animal welfare; [FN194] the organization further defined the link between animal health and welfare by declaring that “animals managed in accordance with the OIE recommendations on animal welfare may be more productive, with associated benefits for food security *291 and poverty alleviation.” [FN195] An ad hoc Animal Welfare Group convened to develop new chapters for the Terrestrial Animal Health Code, which may be used to help uphold animal welfare measures in the future. [FN196] The Agreement's main purpose is to create international standards. The Agreement specifically gives the OIE the power to create those standards for animal safety, and through the OIE's creation of a new chapter, it will formally recognize that animal welfare is interrelated with animal health. At the same time, the OIE's animal welfare chapter could just result in minimum standards. Further attention should be paid to ensure that the OIE's standards do not become the de facto setting (and that countries are allowed to create higher animal welfare standards than those pro-Scribed by the OIE).

However, even without OIE-prescribed international standards, the SPS Agreement should provide a safe-haven for animal welfare measures. While SPS Article 2 mandates that a sanitary or phytosanitary measure be “based on scientific principles and [that it] is not maintained without sufficient scientific evidence,” it also recognizes that there may not be relevant evidence available. [FN197] In that case, under Article 5.7, a WTO member may “provisionally adopt” measures “on the basis of available pertinent information,” but must thereafter try to acquire more information in order to make a “more objective assessment of risk” and to review the measure “within a reasonable period of time.” [FN198] However, in European Communities-- Measures Concerning Meat and Meat Products, [FN199] the Appellate Body found that the European Community's (“EC”) ban of meat from cattle that had received growth hormones was inconsistent with the requirements of the SPS Agreement. [FN200] In that case, the EC created a measure which was more stringent than international standards [FN201] and failed to ensure that its measure was based on an appropriate *292 risk assessment. [FN202] Thus, even measures such as the EC's, which “were previously regarded as purely internal policy measures,” now must be justified to fit under the SPS Agreement's protection. [FN203]

Nevertheless, this case should not undermine the use of the SPS Agreement to defend a battery cage ban. Nations are generally given wide latitude “in setting their own food safety standards ... [and] nearly all bona fide attempts to protect food safety will be consistent with the SPS Agreement.” [FN204] In EC--Measures Concerning Meat , the available scientific evidence specifically did not support the EC's allegation that a hormone ban was necessary. [FN205] Additionally, in the case of a battery cage ban, there is little data on current intensive confinement practices' detrimental effects on animal health and welfare. [FN206] and much of the present data in the U.S. may be inaccurate since it is based on research funded by agribusiness. [FN207] It is clear that more studies need to be conducted by neutral third-parties; however, a few studies not funded by agribusiness do exist, which show the detrimental effects of battery cages on hens' welfare *293 and health. [FN208] Furthermore, in terms of human health risks, the Council for Agricultural Science and Technology (“CAST”), [FN209] with help from the OIE, [FN210] issued a 2005 report concluding that modern day intensive confinement systems have created a world in which “global risks of disease are increasing.” [FN211] In the meantime, the U.S. should be able to enact a measure on a provisional basis under SPS Article 5.7, while alleging insufficient available scientific evidence. [FN212] Under this measure, the U.S. could allege that on the basis of available information, [FN213] intensive confinement severely reduces animal health and welfare, which is directly correlated to sanitary and phytosanitary issues, and it could cite the EU's recent Directive banning battery cages to show that other countries are similarly concerned and are passing similar measures. [FN214]

Of course, an SPS measure such as a battery cage ban could also be seen as a trade barrier due to the fact that it would affect a country's production costs. [FN215] However, a GATT Panel should give these costs less weight considering the fact that the SPS Agreement was created, in part, to protect animal health, which OIE has proclaimed to be connected to animal welfare. [FN216] Therefore, if the welfare of a hen is compromised, so is her health. Additionally, as shown through a recent OIE study, even some developing countries demonstrate an interest in animal welfare concerns [FN217] and organic food production, which can lead to increased animal welfare, [FN218] thus illustrating that both developed and developing *294 countries can still successfully produce products under an appropriately constructed animal welfare trade measure. Based on support from Article XX(b), the SPS agreement, the OIE's acknowledgment of the link between animal health and welfare, and its plan to create animal welfare international standards, [FN219] a battery cage ban should be upheld under the SPS Agreement.

B. The Agreement on Agriculture: Green Box Subsidies

There should also be an opportunity for the AoA to support animal welfare measures. The AoA creates limits on a country's ability to give subsidies to its domestic agricultural producers “depending on how much [the subsidies] distort production and trade.” [FN220] Subsidies that are “highly trade-distorting”' are called “Amber Box;” “minimally trade-distorting” subsidies are called “Blue Box;” and “non-trade-distorting”' subsidies are called “Green Box.” [FN221] The AoA allows countries an unlimited allowance of Green Box subsidies, [FN222] provided that the subsidies are in the form of “publicly-funded government program[s] ... not involving transfers from consumers” and provided that they do not “have the effect of providing price support to producers.” [FN223] An example of a program which would affect production is the Biomass Crop Assistance Program, which “provides direct payments to farmers for establishing crops that can be converted to biomass.” [FN224] However, if properly devised, Green Box subsidies should provide an opportunity for countries to create farm animal welfare programs to increase humane treatment. [FN225] Gaverick *295 Matheny and Cheryl Leahy's article, Farm-Animal Welfare, Legislation, and Trade , [FN226] argues that subsidies to agricultural producers “for more animal-friendly housing, equipment, training, and certification” may meet Green Box requirements. [FN227] However, Green Box subsidies for animal welfare payments have not yet been “explicitly allowed” by the WTO [FN228] and “[b]ecause Green Box payments mean extra costs for governments, they must have widespread political support” [FN229] to rationalize those costs being passed on to taxpayers. Furthermore, some countries within the WTO are pushing to place limits on Green Box subsidies, alleging that they need to be amended to better reflect the concerns of developing countries. [FN230] For example, some developing countries argue that any type of subsidy causes trade distortions, because “[g]overnments in developing countries simply do not have the financial resources needed to subsidize their own farmers at the same levels that farmers in developed countries are being subsidized.” [FN231]

However, the U.S. asserts that animal welfare subsidies should be considered as Green Box subsidies. [FN232] Furthermore, while a country must notify the WTO of its new Green Box programs, it has “a broad amount of discretion in the calculation and classification of [its] own domestic support programs.” [FN233] Given the degree of leeway permitted through self- *296 reporting, countries should be able to experiment with new programs with little oversight. However, this could lead to an abuse of power, as a subsidy program can affect production decisions. If a farmer uses the subsidy to create a more humane production system, the long-term labor costs associated with humane production, which are passed on to consumers in the form of higher prices, may affect the farmer's decision to produce more or less in the future.

On the other hand, if a Green Box subsidy program is created to give farmers financial and technical assistance or “income compensation for loss of competitiveness” [FN234] due to making animal welfare improvements, these changes can be viewed as comparable to U.S. environmental conservation programs that have already been deemed to meet Green Box requirements. [FN235] For example, the Conservation Technical Assistance program, which “provides technical assistance to farmers and ranchers who implement soil and water conservation and water quality improvement,” is considered a Green Box program, [FN236] as is the Conservation Reserve Program, which “provides [technical and financial] assistance to farmers and ranchers in complying with Federal, State, and tribal environmental laws ....” [FN237] Like farmers who utilize these types of environmental conservation subsidies in order to conserve resources, farmers should be able to make their animal production systems more humane without having to sacrifice their market share. Furthermore, a program that provides support for animal-friendly housing should serve as a helpful tool for egg producers to use in order to comply with the new laws in the U.S.; [FN238] the U.S. should welcome such measures, given the recent increase in concern over animal welfare, as evidenced by statutes like Prop 2.


Animal welfare is connected to public morals, animal health, and food safety-- issues that are all acknowledged in GATT Articles XX(a), *297 XX(b), and the SPS Agreement. [FN239] Therefore, the WTO should recognize animal welfare measures such as the battery cage bans that countries are beginning to enact. Although there are costs involved in implementing a battery cage ban given that producers will have to create new production systems, [FN240] WTO dispute settlement panels should find that any potential costs to a country will be outweighed by the fact that the measure is not discriminatory and it truly goes to the heart of Articles XX(a), (b), or the SPS Agreement. Finally, the U.S. should develop and offer Green Box subsidies to incentivize producers to create more humane agricultural production systems, especially given the recent outpouring of public support for the more humane treatment of animals. [FN241]

Public sentiment in the U.S. looks longingly back at traditional farming practices, when animals were perhaps treated more like sentient beings, and less like egg making machines. Yet, at the same time, factory farms still dominate the agricultural landscape. Globalization has and continues to change the way that our food is produced, yet current agricultural methods will need to be revised to comply with demands for more ethical practices. [FN242] While the WTO traditionally left animal welfare out of trade negotiations, the changing tide of public concern suggests that it is time to take a practical look at the interrelatedness of trade and animal welfare. As Steven Wise so succinctly stated, “There is only one reason not to determine what rights farmed animals are due and recognize them. That is the reason that once justified human slavery: powerful economic interests are arrayed against it.” [FN243] More humanely produced foods are in real demand, “based on consumers' common sense understanding that such practices as gestation crates, veal creates and battery cases are not humane.” [FN244] One day, economics and animal welfare *298 will need to strike a balance, and both interests will need to be preserved within international trade negotiations. Though it may not be today, we are moving in the right direction.

Cages prevent hens from performing the bulk of their natural behavior, including nesting, perching, dustbathing, scratching, foraging, exercising, running, jumping, flying, stretching, wing-flapping, and freely walking. Cages also lead to severe disuse osteoporosis due to lack of exercise. Alternative, cage-free systems allow hens to move freely through their environment and engage in most of the behavior thwarted by battery-system confinement ... all caged hens are permanently denied the opportunity to express most of their basic behavior ... [t]he science is clear that this deprivation represents a serious inherent welfare disadvantage compared to any cage-free production system ...

[FN157] . Neither of the two alternatives to a complete seal ban. (products from “humanely killed” seals or labeling to give purchasers information about the slaughter method), would work, because “[c]ommercial seal hunts, particularly in the environments in which they take place, cannot be consistently humane,” and because the seal hunt is the type of event “when moral sensibility demands that trade in an inhumanely produced product is banned ... that public morality is offended by the very presence on the market of something which is inhumanely produced.” Stewart & Thomas, supra note 156.

[FN202] . EC--Measures Concerning Meat, supra note 199, ¶ 208. The EC invoked the “precautionary principle” in connection with SPS Article 5.7, which allows a WTO member to adopt SPS measures on a provisional basis when there is insufficient scientific evidence (however, WTO members must still follow Article 5.7 guidelines). Id. ¶ 13; SPS, supra note 134, art. 5.7. However, the Appellate Body “rejected this argument ... the precise bounds of the precautionary principle remain unsettled ...
