The U.S. Chamber of Commerce (COC) recently filed a lawsuit against the DHS to challenge the legality of requiring federal contractors and sub-contractors to use the DHS’ E-Verify system. The lawsuit challenges the federal government’s use of an Executive Order coupled with Federal Procurement laws to make E-Verify mandatory for federal contractors with project exceeding $100,000 and for sub-contractors with projects exceeding $3,000. The COC also challenged expanding E-Verify to require reconfirming the employment authorization of existing workers. These provisions are currently scheduled to become effective on January 15, 2009. The COC has requested an expedited review of its challenge so that a temporary injunction can be issued prior to the implementation date of the regulation. Joining the COC as co-plaintiffs in the lawsuit are the Associated Builders and Contractors, the Society of Human Resources Management, the American Counsel on International Personnel and the HR Policies Association.
