What is one check the legislative branch has over the judicial branch?

overriding presidential vetos
Approving laws
Overriding court decisions
Approving judicial nominees

One check that the legislative branch has over the judicial branch is approving judicial nominees. Members of the legislative branch, particularly the Senate, have the power to confirm or reject the president's nominations for federal judgeships, including Supreme Court justices. This check allows the legislative branch to ensure that the individuals appointed to the judiciary are qualified and have the necessary legal expertise. By approving or rejecting these nominees, the legislative branch directly influences the composition and direction of the judicial branch.

so whats the answer?

The answer is approving judicial nominees.
