If a trade agreement that reduces tariffs or non-tariff barriers to trade negotiated by the executive branch meets the guidelines set by Congress , the TPA allows Congress to "consider the required implementing bill under expedited procedures pursuant to which the bill may come to the floor without action by the leadership." The implementing bill is guaranteed an up-or-down vote with no amendments. An implementing bill may go through the expedited process if it follows the congressional guides and: (1) the trade agreement was negotiated during a set time period for which the TPA is in effect; (2) the agreement follows negotiation objectives set by the statute; and (3) during the negotiation process, the executive branch sent required notifications and conducted consultations with Congress and other stakeholders. The 2002 version of the authority created an additional requirement for 90-day notice to Congress before negotiations could begin.
