The Animal Welfare Act (AWA) (7 U.S.C. §§ 2131–2159) regulates the housing, sale, transport, treatment, and exhibition of animals. Defendants, United States Secretary of Agriculture, licensed Plaintiff, Lancelot Kollman, as an exhibitor under the AWA. However, after the death of two lions and Kollman’s failure to contest charges, the Secretary revoked Kollman's license. Still, Hawthorn, a company that holds an exhibitor license, hired Kollman to train a “tiger act” for performance at circuses throughout the United States. Hawthorn then asked Kollman to travel with the tigers and perform the act. However, the USDA received complaints about Kollman's participation in the act, despite having his license revoked. The USDA investigated and determined that Kollman was prohibited from exhibiting animals as an employee of Hawthorn. Kollman, sued Thomas J. Vilsack, the United States Secretary of Agriculture, and Chester A. Gipson, a deputy administrator of animal care.  Kollman sued for a declaration that, at a circus maintained by his employer, Hawthorn Corporation, he could publicly perform the tiger act. The Defendants moved for summary judgment.  The United States District Court, M.D. Florida, Tampa Division, held that the Defendants' motion for summary judgment was Granted. The court reasoned that Kollman was barred from presenting animals on behalf of Hawthorn because regardless of his status as a Hawthorn employee, Section 2.10(c) of the Animal Welfare Act clearly prohibited Kollman, as an individual with a revoked license, from exhibiting an animal. Secondly, Section 2.10(c) was unambiguous.

In this Utah case, the defendant appeals the decision of the district court finding him guilty on four counts of failing to maintain a city dog license and one count of running an illegal kennel. In December 2005, a Kanab City animal control officer responded to numerous complaints of barking dogs at Defendant's residence. This officer observed four dogs over the age of three months on the premises during two separate visits to Defendant's home that month and on subsequent random visits in the following months. On appeal, defendant argued that the city ordinance on which his conviction for operating an illegal kennel is based is unconstitutionally vague. This court disagreed, finding that an ordinary person reading the ordinance would understand that, in order to keep more than two dogs over the age of three months in the same residence, a citizen must register for a kennel permit.
