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 Supreme Court relied on the Supremacy Clause to hold that the federal law controlled and could not be nullified by state statutes or officials. In Edgar v. MITE Corp., 457 U.S. 624 (1982), the Supreme Court ruled: A state statute is void to the extent that it actually conflicts with a valid Federal statute.
