Checks and balances. The Executive branch has power over (checks the power of) the Judiciary branch by way of choosing who to appoint. The Legislative branch has power over (keeps in check) the Judiciary branch by way of choosing whether to confirm the appointments. The Legislative Branch also has power over (keeps in check) the Executive branch because the appointments to the Supreme Court require their approval.
Congress must approve all appointments.
In the United States the Congress, or legislative branch confirms federal judicial appointments. It is the Senate as upper house of the Congress that has the Constitutional power to confirm federal judges, and Supreme Court nominees.
Congress has the ability to overrule the President's veto power with a 2/3 majority vote. Furthermore, Congress has the power to impeach the President, and must confirm the President's choices (i.e. appointment of the Supreme Court, etc.). Congress checks the Supreme Court in a few ways as well. First of all, it has to confirm the President's appointments of Supreme Court judges. It also has the power, once again, of impeachment, and has the ability to amend the Constitution.
