Majority Republicans who don't like the state's new congressional and legislative districts want the Arizona Legislature to go to court to challenge one or both maps and the voter-created redistricting commission's authority.

The House and Senate on Wednesday approved Republican motions authorizing their top leaders to file or join legal redistricting-related legislation.

Republicans say the commission didn't obey constitutional mapping criteria and processes. They also say the voter-approved measure creating the commission may violate a U.S. Constitutional provision saying legislatures are responsible for congressional redistricting.

Two Republican-backed lawsuits challenging both maps have already been filed in state and federal courts.

The suits ask judges to order drawing of new maps and one requests a court-drawn interim legislative map for use in this year's elections.
