The North American Free Trade Agreement (NAFTA) and the General Agreem
ent on Tariffs and Trade (GATT) shift power away from state and local
government in the federal system. They impose new rules on the exercis
e of state and local powers over procurement and the regulation of foo
d, environmental, health, product and service standards, investments,
services, financial services, economic development, and land transport
ation. States will have to comply with various reporting and registrat
ion requirements, and may be subject to stricter nondiscrimination obl
igations toward imported goods and services than under the commerce cl
ause of the U.S. Constitution. State and local governments will be jud
ged by international panels, whose judgments the United States must en
force or suffer trade sanctions from aggrieved trading partners. Yet,
states have not strongly opposed NAFTA and GATT. The greatest state op
position has been to automatic preemption, which the Clinton administr
ation promised to avoid as much as possible. Nevertheless, increased p
ower over federalism has moved to the executive branch, business, and
trade-dispute panels, with less power for state and local governments.
