What did the courts get the power of judicial review?

The power of judicial review was established in the United States through the landmark Supreme Court case Marbury v. Madison in 1803. In this case, Chief Justice John Marshall asserted that it is the Judiciary's role to interpret the Constitution and determine the validity of legislative and executive actions. This ruling affirmed that courts have the authority to invalidate laws and actions that conflict with the Constitution, thereby solidifying the principle of checks and balances within the government. Judicial review has since become a fundamental aspect of the American legal system.
