In 1977, the Department of Transportation (DOT) adopted a passive-restraint standard (known as Standard 208) that required new cars to have either air bags or automatic seat belts. By 1981, it had become clear that all of the major auto manufacturers would install automatic seat belts to comply with this rule. The DOT determined that most purchasers of cars would detach their automatic seat belts, rendering them ineffective. Consequently, the department repealed the regulation. State Farm Mutual Automobile Insurance Co. and other insurance companies sued in the District of Columbia Circuit Court of Appeals for a review of the DOT's repeal of the regulation. That court held that the repeal was arbitrary and capricious because the DOT had reversed its rule without sufficient support. The motor vehicle manufacturers, which initially had wanted to avoid the costs associated with implementing Standard 208, then appealed this decision to the United States Supreme Court. What will result?
