All Writs Act Law and Legal Definition

The All Writs Act is a U.S. federal statute that gives the U.S. Supreme Court and all other courts established by Congress the power to issue necessary and appropriate writs in aid of their jurisdiction. However, such writs must be in conformity with the usages and principles of law. The Act was codified at 28 USCS § 1651. In its original form, the All Writs Act was a part of the Judiciary Act of 1789. The current form of the Act was passed in 1911, and has been amended several times after that.
