The head of the Department of Transportation reviewed a film that demonstrated the effectiveness of air bags in automobiles. He then passed a rule that Ford Motor Company must retrofit, without charge to the automobile owner, all of its 1985 models as an experiment on the safety of the air bag. Ford refused to do so. The DOT held a hearing and decided to fine Ford $1 million for violating its regulation. A notification of this decision was mailed to Ford. What constitutional issues does this case raise?
