Aztron, Inc. hires the Millstern Ad Agency to begin an advertising campaign. This campaign involves placing 30 billboards on 30 highways, each one 10 yards from the road. Before the billboards are placed, the state legislature passes a statute that requires all billboards to be placed at least 50 yards from the road. Millstern wants to continue the campaign, but Aztron says the agency has been terminated by operation of law. Has the agency been terminated? Why or why not?
