On September 1, 2009, four business associations filed in federal court for an emergency injunction to delay the implementation of the new E-Verify requirement for certain federal contractors, which will become effective on September 8, 2009, under the Federal Acquisition Regulation (FAR).  The pleading and brief may be read here.  Check back for updates.

UPDATE:  The U.S. District Court for the Southern District of Maryland denied the injunction filed by the business coalition led by the U.S. Chamber of Commerce; however, an appeal will be filed with the Court of Appeals for the 4th Circuit.  Until a decision is reached, the E-Verify rule for Federal contractors is in effect.
