What principle gave the supreme court a central role in American government?

The principle of judicial review, established in the landmark case Marbury v. Madison (1803), gave the Supreme Court a central role in American government. This principle allows the Court to interpret the Constitution and invalidate laws or executive actions that it finds unconstitutional, thereby serving as a check on the powers of the legislative and executive branches. As a result, the Supreme Court has become a critical arbiter of constitutional interpretation and protector of individual rights.
