Nevada's highest court unanimously overruled a lower court decision allowing a long-dormant law to go into effect that required parental notification or a judicial bypass for minors to undergo an abortion.

The decision filed Thursday noted that the 40-year-old law "is unconstitutionally vague, that appellants demonstrated irreparable harm, and the balance of hardships and public interests favor appellant."

The decision comes after years of litigation over the law, which took effect following a federal judge's lifting of an administrative block in July 2025. 

Planned Parenthood Mar Monte filed the lawsuit in state court seeking to halt its implementation. The California-based abortion rights group and health care provider, along with a physician using the pseudonym Dr. Doe, argued the 1985 law, SB510, had a host of issues, including relying on a "hazy, inadequate" process for minors to secure an exception to the law that violates guarantees of procedural due process and lacks guidance or rules to govern it.

Following the Supreme Court's decision, it's expected that the law will be struck down in its entirety, though the process is still ongoing.
