Questions: In addition to asserting the power to invalidate state laws, the Marshall Court established its authority to overrule decisions of the highest state appellate courts on questions of law. constitutional state federal common

The answer is: federal

Explanation for each option:

1. Constitutional: While the Marshall Court did play a significant role in interpreting the Constitution, the specific authority to overrule decisions of the highest state appellate courts on questions of constitutional law is not the most precise answer here. The broader category that encompasses constitutional law is federal law.

2. State: The Marshall Court did not establish its authority to overrule state appellate courts on questions of state law. State courts are the final arbiters of state law.

3. Federal: This is the correct answer. The Marshall Court, under Chief Justice John Marshall, asserted the power to overrule decisions of the highest state appellate courts on questions of federal law. This was established in cases such as _Martin v. Hunter's Lessee_ (1816), where the Supreme Court held that it had the authority to review state court decisions involving federal law.

4. Common: Common law refers to law developed through court decisions rather than statutes. While the Marshall Court did influence common law, the specific authority to overrule state appellate courts on questions of common law is not the most accurate answer in this context. The focus here is on federal law.
