Lawmakers Seek to Appeal Ruling on Arizona Birth-Certificate Requirement

Legislative Leaders File Motion to Intervene

Arizona House Republicans have filed a motion in federal court to defend a long-standing state law governing amendments to birth certificates. House Speaker Steve Montenegro announced the filing on behalf of legislative leaders seeking to intervene, request a stay, and appeal a September 30 ruling that struck down part of Arizona’s birth-certificate statute.

The move comes after Attorney General Kris Mayes did not indicate whether her office would pursue an appeal. Lawmakers say their action ensures that the law—Arizona Revised Statutes § 36-337—is defended as written.

Federal Court Decision

U.S. District Judge James Soto, appointed during the Obama administration, issued a permanent injunction barring enforcement of the statute’s requirement that an individual undergo a “sex change operation” before the Arizona Department of Health Services could amend the sex marker on a birth certificate. The order directed the department to revise its regulations within 120 days and to allow amended certificates based on a doctor’s attestation of a “sex change,” without surgical confirmation.

Speaker Montenegro’s Statement

Speaker Montenegro emphasized the Legislature’s responsibility to uphold enacted statutes when state officials decline to act. “Arizona’s laws are not optional,” he said. “When a federal court rewrites a statute, the Legislature has a duty to defend it. If the Attorney General won’t defend Arizona’s laws, we will.”

He warned that the ruling “opens the door for anyone to change the sex marker on a birth certificate with just a doctor’s note,” which he said could undermine the integrity of vital records.

What the Motion Seeks

The motion—filed by Speaker Montenegro and Senate President Warren Petersen—asks the federal court to permit legislative leaders to intervene for purposes of appealing the summary judgment, permanent injunction, and final judgment orders. It also requests a stay pending appeal, which would pause the injunction while the Ninth Circuit Court of Appeals reviews the case.

According to the filing, House and Senate leaders have contacted the Attorney General’s Office several times since October 1 to determine whether the state intended to appeal. To date, they say, no decision has been communicated.

HB 2438: The Legislature’s Policy Framework

The dispute over A.R.S. § 36-337 reflects policy language at the center of House Bill 2438, introduced earlier this year during the Fifty-Seventh Legislature. The measure proposed to amend Section 36-337 “in order to protect the integrity and accuracy of vital records.”

Under HB 2438, amendments to birth certificates would be permitted only under defined conditions—such as adoption documentation, voluntary acknowledgment of paternity, or court orders. The bill reaffirmed that the sex designation of a person may not be changed on the original birth certificate as a result of sex change surgery, explicitly barring such revisions. It also added procedural details requiring written requests, physician verification of surgeries or chromosomal evidence, and strict documentation for any change of name or paternity information.

The bill further provided that all evidentiary documents associated with amendments must be sealed and accessible only under limited statutory or court-ordered circumstances. The legislation was designed, according to its sponsors, to safeguard the accuracy of official records by ensuring that amendments occur only when a factual inaccuracy is proven beyond a reasonable doubt.

Veto and Legislative Aftermath

House Bill 2438, sponsored by Representative Rachel Keshel, passed both chambers but was later vetoed by Governor Katie Hobbs. The governor’s action effectively maintained existing administrative discretion on vital-records changes. The subsequent federal court ruling further expanded those allowances by eliminating the surgical requirement altogether.

Following the veto and the court’s decision, Republican legislative leaders said they felt compelled to act to preserve what they consider the legislative intent behind A.R.S. § 36-337. The current court filing is therefore intended not only to appeal the ruling but also to affirm the Legislature’s constitutional role in defending state law when other state officials choose not to.

Next Steps

The federal court will now determine whether legislative leaders may formally intervene in the case. If granted, the appeal will proceed to the Ninth Circuit. Meanwhile, the Department of Health Services has been directed to prepare rule changes to comply with Judge Soto’s injunction unless a stay is issued.

For now, Arizona’s policy on amending birth certificates remains in transition as lawmakers, state officials, and the courts weigh the balance between administrative flexibility and statutory clarity.
