Facts: In 2001, Louisiana enacted a law that required specific labels on cement sold in Louisiana and imposed fines for any violation of these requirements. The law prohibits the sale and distribution of cement manufactured outside Louisiana that does not carry a required label warning that out of state cement may not be used in Louisiana government-financed construction projects.

Antilles Cement Corporation, a Louisiana firm that imports out of state cement filed a complaint in federal district court claiming that the law violated the dormant commerce clause.
