PHOENIX (AP) — Arizona Gov. Jan Brewer filed an appeal Wednesday with the U.S. Supreme Court to overturn a ruling that put on hold key parts of the state’s immigration enforcement law.

The appeal comes as Brewer faced a deadline for contesting a district court’s decision that, among other things, barred a requirement that police — while enforcing other laws — question the immigration status of those they suspected of being in the country illegally.

Brewer lost her first appeal in April when a three-judge panel of the 9th Circuit Court of Appeals rejected her request to overturn the decision.

Lawyers for the governor argued that Arizona bears the brunt of America‘s border problems and that the 9th Circuit’s decision conflicts with Supreme Court precedents and with immigration decisions from another appeals court. The 9th Circuit had said the federal government is likely to be able to prove the law is unconstitutional and likely to succeed in its argument that Congress has given the federal government sole authority to enforce immigration laws.

The governor said in a written statement that her appeal raises issues that apply to other states. “It’s about the bedrock constitutional principle of federalism under which states have the inherent authority to protect the safety and welfare of their citizens,” Brewer said.
