The leading Supreme Court case is Ex parte Garland (1867). Justice Stephen J. Field, writing for the Court in a 5-4 decision, held that the President’s pardoning power is ‘’unlimited,’’ and ‘’It extends to every offense known to the law, and may be exercised at any time after its commission, either before legal proceedings are taken, or during their pendency, or after conviction and judgment.’’

Accordingly, the Constitution simply provides that the President ‘’shall have power to grant reprieves and pardons for offenses AGAINST THE UNITED STATES EXCEPT IN CASES OF IMPACHMENT.... (Article II, section 2).
