Question

what was the ruling in marbury vs madison, what did mean?

Explanation:

In Marbury v. Madison (1803), the Supreme Court ruled that Marbury had a right to his commission, but the Court could not grant it. The Judiciary Act of 1789 provision enabling Marbury to sue in the Supreme Court was unconstitutional. This established judicial review, the power of the courts to declare laws unconstitutional.
