The fast track authority for brokering trade agreements is the authority of the President of the United States to negotiate international agreements that Congress can approve or deny but cannot amend or filibuster.  Renamed the trade promotion authority (TPA) in 2002, fast track negotiating authority is an impermanent power granted by Congress to the President.  Fast track authority remained in effect from 1975 to 1994, pursuant to the Trade Act of 1974, and from 2002 to 2007 by the Trade Act of 2002.  Although it technically expired in July 2007, it remained in effect for agreements that were already under negotiation until their passage in 2011.  The following year, the Obama administration sought renewal of TPA, and in June 2015, it passed Congress and was signed into law by the President.  Known as the Trade Preferences Extension Act of 2015, the legislation conferred on the Obama administration "enhanced power to negotiate major trade agreements with Asia and Europe."
