An email from the Northwest Mining Association was forwarded, informing their members that NWMA filed a complaint in federal district court in Arizona "seeking to overturn [Interior] Secretary Salazar’s Public Land Order withdrawing more than 1 million acres from operation of the Mining Law. Mountain States Legal Foundation is representing NWMA in this action. There are 7 claims for relief, two relating to violations of FLPMA and the NFMA; four related to violations of NEPA; and the seventh seeks to declare §204 of FLPMA unconstitutional because it violates the Presentment Clause of the U.S. Constitution."

There are a number of reports circulating that other groups are planning suits, and not surprisingly, that several mining opponents will seek to intervene in support of the withdrawal.
Update, 3-8-12 5;14AM: the Mohave Valley News reports that Mohave County Supervisors on Monday will consider joining one of the lawsuits.
