What was the most significant result of the ruling in marbury v. madison? the ruling determined that the judiciary act of 1789 was unconstitutional. the ruling determined that the supreme court should not hear marbury’s case. the ruling was made by chief justice john marshall of the supreme court. the ruling expanded the powers of the federal government.

Marbury v Madison gave the power to the federal government to strike down laws, statutes, and executive actions that do not aligned with the U.S. Constitution. This strengthen the position of federal government in case they want to override state laws which contradict the constitution.
