The standard veto is when the president refuses to sign a bill passed by Congress. For a standard veto, this refusal and the rationale behind it is put in writing and sent back to Congress. A pocket veto is a little different. A pocket veto is used when a president simply ignores the bill until Congress dismisses and leaves its current session. The result is that the bill is vetoed because when Congress is not in session, they cannot override the veto.
Courts and judges make up the judicial branch of our government. There are three separate court levels in this branch, District Courts, Court of Appeals, and the Supreme Court. The Constitution created the Supreme Court and gave the power of establishing other courts to the Congress.
