At a press conference on Friday, Arizona Attorney General Tom Horne said that his office would not pursue an appeal in two rulings that struck down the state's ban on gay marriage.

U.S. District Judge John Sedwick on Friday ordered the state to immediately begin issuing marriage licenses to gay and lesbian couples.

Arizona is one of the three states affected by two rulings out of the Ninth Circuit Court of Appeals in San Francisco striking down bans in Nevada and Idaho. The rulings created a precedent in the circuit that lower courts must follow.

Horne said on Friday that an appeal would be “futile” and that the state would abide by the court's order.

Horne instructed clerks to immediately begin issuing such licenses.

“Effective immediately, the clerks of Arizona county superior courts cannot deny a marriage license to any otherwise eligible licensees on the grounds that the license permits a marriage between persons of the same sex,” Horne said in a letter to clerks.

Brewer, a Republican, also released a statement in which she claimed that the federal courts had “thwarted the will of the people and further eroded the authority of states to regulate and uphold our laws.”

“Simply put, courts should not be in the business of making and changing laws based on their personal agendas. It is not the role of the judiciary to determine that same-sex marriages should be allowed. Historically and traditionally, that power belongs to the states, and to the people. If society wants to recognize same-sex marriage or civil unions, that decision should be made through our elected representatives or at the ballot – not the courts,” she said.
