What major check does the congress have over the judicial branch?

One major check Congress has over the judicial branch is its power to confirm or reject judicial appointments made by the President, including Supreme Court justices. Additionally, Congress can pass legislation that can alter the jurisdiction of federal courts or modify the structure of the judicial system. Furthermore, Congress holds the authority to impeach and remove federal judges, including Supreme Court justices, for misconduct. These powers enable Congress to exert significant influence over the judiciary.
