A complaint that Arizona’s Independent Redistricting Commission failed to follow several provisions of the law in drawing new congressional districts will continue, although a judge rejected some portions of the lawsuit. Maricopa County Superior Court Judge Mark Brain told the plaintiffs to file a new, more concise complaint, saying their original lawsuit was too long and contained unneeded pages rehashing past conflicts with the commission.

Joseph A. Kanefield, a litigation partner in Ballard Spahr’s Phoenix office and one of the commission’s attorneys, said the panel is pleased that half of the counts were tossed and that the plaintiffs were ordered to write a shorter complaint.

“We’re confident that we will prevail on the merits,” Mr. Kanefield said, adding that he would not expect any modifications to the new congressional map. The case is expected to continue into 2013.
