Number: RS22784 Title: Obstruction of Congress: An Abridged Overview of Federal Criminal Laws Relating to Interference with Congressional Activities Authors: Charles Doyle, American Law Division Abstract: Obstruction of justice is the frustration of governmental purposes by violence, corruption, destruction of evidence, or deceit. It is a federal crime. In fact, it is several crimes. Obstruction prosecutions regularly involve charges under several statutory provisions. Federal obstruction of justice laws are legion; too many for even passing reference to all of them in a single report. The general obstruction of justice provisions are six: 18 U.S.C. 1512 (tampering with federal witnesses), 1513 (retaliating against federal witnesses), 1503 (obstruction of pending federal court proceedings), 1505 (obstruction of pending Congressional or federal administrative proceedings), 371 (conspiracy), and contempt. Other than Section 1503, each prohibits obstruction of certain Congressional activities. In addition to these, there are a host of other statutes that penalize obstruction by violence, corruption, destruction of evidence, or deceit. Pages: 6 Date: Updated December 27, 2007
