The Animal Enterprise Terrorism Act (AETA) is a United States federal law (Pub.L. 109–374; 18 U.S.C. § 43) that prohibits any person from engaging in certain conduct "for the purpose of damaging or interfering with the operations of an animal enterprise." The statute covers any act that either "damages or causes the loss of any real or personal property" or "places a person in reasonable fear" of injury.
The law amends the Animal Enterprise Protection Act of 1992 (Pub.L. 102–346) and gives the U.S. Department of Justice greater authority to target animal rights activists. The AETA does so by broadening the definition of "animal enterprise" to include academic and commercial enterprises that use or sell animals or animal products. It also increases the existing penalties, includes penalties based on the amount of economic damage caused, and allows animal enterprises to seek restitution.
The law was originally introduced in the 109th Congress by Thomas Petri (R-WI) and Senators Dianne Feinstein (D-CA) and James Inhofe (R-OK). The final version of the bill, S. 3880., was passed in the United States Senate on September 29, 2006, by unanimous consent, a Senate procedure that is used to expedite the passage of non-controversial bills without an actual vote. On November 13, 2006, the House passed the bill under suspension of the rules, a procedure generally used to quickly pass non-controversial bills. The lone dissenting statement was made by Representative Dennis Kucinich, who said that the bill was "written in such a way as to have a chilling effect on the exercise of the constitutional rights of protest." Neither Rep. Kucinich nor any other members of the House of Representatives called for a recorded vote; the bill passed with a voice vote. The bill was signed by President George W. Bush on November 27, 2006. Earlier versions of the bill were known as S. 1926 and H.R. 4239. The bill is described by the author as being intended to "provide the Department of Justice the necessary authority to apprehend, prosecute, and convict individuals committing animal enterprise terror."
