While, IMHO, it should have happened many more times, Congress overrode Bush's veto of at least four bills and the Supreme Court ruled against him several times. One example of the latter was when the Supreme ruled in June 2008 that Section 7 of the Military Commissions Act of 2006 (which basically eliminated habeas corpus for Guantanamo prisoners) unconstitutional. One example of the former was the override of his veto of the Medicare Improvements for Patients and Providers Act in July 2008.
