PHOENIX (AP) – Arizona’s redistricting commission says a Republican-backed lawsuit challenging new legislative districts should be put on hold in federal court until related issues are resolved by state courts.

The commission’s motion says recent papers by the challengers make it clear that their case largely depends on interpretations of state law, not just the federal one-person, one-vote rule.

At issue in the case is whether population variances among districts approved by the commission are too big.

A three-judge federal court panel considering the case has said the case needs to go to trial March 25 so it can be resolved in time to avoid affecting 2014 elections.

The commission says the case still can be resolved in time even with waiting for state court rulings on issues related to population variances.
