A trial was held in Harris v Arizona Independent Redistricting Commission March 25-29. This is the case brought by Arizona Republicans that argues the Independent Redistricting Commission improperly favored Democrats over Republicans when it drew the legislative district boundaries, following the 2010 census.
The three judges are Richard Clifton, a 9th circuit judge appointed by President George W. Bush; Neil Wake, a U.S. District Court Judge also appointed by George W. Bush; and Roslyn Silver, a President Clinton appointee. Before Wake was a federal judge, he was an Arizona attorney who handled Republican Party redistricting cases after the 2000 census and also after the 1990 census. Here is a story about the trial. The main issue is whether population deviations in the size of the districts are unconstitutionally large, or whether the deviations were for the legitimate purpose of helping to conform the maps to the Voting Rights Act. A side issue is whether the Commission’s procedures were fair.
The post-trial briefs are due April 10. Meanwhile, there is also an Arizona federal case over whether a state violates the U.S. Constitution when it lets redistricting commissions, instead of the legislature itself, draw U.S. House district boundaries. Last summer, the Arizona Redistricting Commission asked Judge Paul G. Rosenblatt to dismiss the case, and a decision could come out at any time. That case is Arizona State Legislature v Arizona Independent Redistricting Commission, 2:12-cv-1211.
