CASE SUMMARY 17.4 Ranchers Cattlemen Action Legal Fund United Stockgrowers of America v. U.S. Department of Agriculture, 499 F.3d 1108 (9th Cir. 2007) ARBITARY AND CAPRICIOUS In response to outbreaks of mad cow disease, the Food and Drug Administration and the U.S. Department of Agriculture (USDA) implemented a number of regulations to protect American consumers and cattle herds. Chief among them was a regulation banning cattle imports from countries in which mad cow disease was known to exist. Shortly after the ban went into effect, the USDA partially reversed course and published a proposed rule allowing certain low-risk products into the United States. During the comment period, some groups objected to the proposed rule due to evidence of potential contamination even in low-risk products. The agency then published its final rule, which modified existing regulations to allow the import of low-risk products. The Ranchers Cattlemen Action Legal Fund United Stockgrowers of America challenged the agency's decision to allow low-risk products as arbitrary and capricious even though the agency had held several comment periods. CASE QUESTIONS 1. Is the decision arbitrary and capricious? Why or why not? 2. Does the fact that the agency held several comment periods impact your analysis?
