On June 7, the Arizona legislature filed a lawsuit in federal court, arguing that the U.S. Constitution’s Article One requires that only state legislatures can draw U.S. House district boundaries. In Arizona, an independent redistricting commission draws the boundaries.
The Arizona legislature has a large Republican majority. A few months ago, Republicans were so displeased with the 2011 U.S. House district boundaries that Republican Governor Jan Brewer and the State Senate removed the chair of the redistricting commission. However, the State Supreme Court then reinstated the Chair.
The case is Arizona State Legislature v Arizona Independent Redistricting Commission, 2:12cv-1211. The Complaint asks for a three-judge court.
