In a complex sentence, the role of the subordinating conjunction and the dependent clause is to establish a time, a place, a reason, a condition, a concession, or a comparison for the main clause. The subordinating conjunction provides the bridge between the main clause and the dependent clause.
The definition of Act of Supremacy in the law of the United States, as defined by the lexicographer Arthur Leff in his legal dictionary is: An English statute of 1558 establishing the supremacy of the Crown in ecclesiastical matters.
The Supremacy Clause is a clause within Article VI of the U.S. Constitution which dictates that federal law is the supreme law of the land. This means that judges in every state must follow the Constitution, laws, and treatises of the federal government in matters which are directly or indirectly within the government's control. Under the doctrine of preemption, which is based on the Supremacy Clause, federal law preempts state law, even when the laws conflict. Thus, a federal court may require a state to stop certain behavior it believes interferes with, or is in conflict with, federal law.
