The owners of a Yuma, Arizona-based dairy have filed a petition for review before the U.S. Supreme Court, seeking a hearing on their challenge to the Milk Regulatory Equity Act of 2005, which apparently requires independent producer-handlers to join a dairy cooperative or pay federal marketing fees. Hettinga v. United States, No. 12-506 (U.S., petition for writ of certiorari filed October 19, 2012). According to the Hettingas, one of the few remaining independents in the United States, lawmakers singled out their dairy when enacting a law that has forced them to sell milk at a higher price than they want to charge. The D.C. Circuit Court of Appeals agreed with the district court that the law did not constitute a bill of attainder nor did it violate the Equal Protection and Due Process clauses. Hettinga v. United States, No. 11-5065 (D.C. Cir., decided April 13, 2012).
