PHOENIX — Gov. Jan Brewer appointed her third justice today to the five-member Arizona Supreme Court.

The governor chose Court of Appeals Judge Ann Scott Timmer, a Republican, over Maricopa County Superior Court Judge Douglas Rayes, also a Republican, and Democrat Diane Johnsen. The Arizona Constitution required Brewer to make her pick from the three nominees sent to her by the Commission on Appellate Court Appointments.

Timmer, 52, is the fourth woman since statehood to serve on the high court.

“Judge Timmer has a record of integrity and achievement in the legal profession, has proven herself as a well-respected and fair-minded jurist on the Arizona Court of Appeals, and will make an excellent addition to our Arizona Supreme Court,” Brewer said in a prepared statement.

The appointment comes as Brewer is pushing a constitutional amendment to require that she and future governors get at least eight names from which to choose. Existing provisions do not prohibit such a large list but require only a minimum of three.

Proponents of Proposition 115 argue the governor, as an elected official, should have maximum flexibility to choose among all qualified candidates. Foes have said such a requirement dilutes the purpose of the nominating commission to submit only the most qualified.
