The Supreme Court cleared the way Monday for California schools to tell parents if their children identify as transgender without getting the student's approval, granting an emergency appeal from a conservative legal group.

The order blocks for now a state law that bans automatic parental notification requirements if students change their pronouns or gender expression at school.

The split decision comes after religious parents and educators challenged California school policies aimed at preventing schools from outing students to their families. Two sets of Catholic parents represented by the Thomas More Society say it caused schools to mislead them and secretly facilitate the children's social transition despite their objections.

California, on the other hand, argued that students have the right to privacy about their gender expression, especially if they fear rejection from their families. The state said that school policies and state law are aimed at striking a balance with parents' rights.

The high court majority, though, sided with the parents and reinstated a lower-court order blocking the law and school policies while the case continues to play out.

"The parents who assert a free exercise claim have sincere religious beliefs about sex and gender, and they feel a religious obligation to raise their children in accordance with those beliefs. California's policies violate those beliefs," and burden the free exercise of religion, the majority wrote in an unsigned order.

The court's three liberal justices publicly dissented, saying the case is still working its way through lower courts and there was no need to step in now. "If nothing else, this Court owes it to a sovereign State to avoid throwing over its policies in a slapdash way, if the Court can provide normal procedures. And throwing over a State's policy is what the Court does today," Justice Elena Kagan wrote.

Conservative Justices Samuel Alito and Clarence Thomas, meanwhile, noted they would have gone further and granted teachers' appeal to lift restrictions for them.

The Thomas More Society called the decision "the most significant parental rights ruling in a generation."

California Gov. Gavin Newsom's office defended the law, saying teachers should be focused on instruction, not required "to be gender cops."

The order "undermines student privacy and the ability to learn in a safe and supportive classroom, free from discrimination based on gender identity," said Marissa Saldivar, a spokesperson for the Democratic governor.

The Supreme Court has ruled for religious plaintiffs in other recent cases, including allowing parents to pull their children from public-school lessons if they object to storybooks with LGBTQ+ characters.

The California order comes months after the court upheld state bans on gender-identity-related healthcare for minors. The justices also seem to be leaning toward allowing states to ban transgender athletes from playing on girls sports teams.

School policies for transgender students, meanwhile, have also been on the court's radar in other cases. The court rebuffed another similar case out of Wisconsin in December, but three conservative justices indicated they would have heard the case. Justice Samuel Alito called the school policies "an issue of great and growing national importance."

The justices have been weighing whether to hear arguments in cases out of states like Massachusetts and Florida filed by other parents who say schools facilitated social transition without informing them.

The Trump administration, meanwhile, found in January that California's policies violated parents' right to access their children's education records. The Justice Department also sued after determining the states' transgender athlete policies violate federal civil rights law.

As U.S. and Israeli forces pounded Iran, and Tehran and its affiliates retaliated by firing missiles at targets across the Mideast on Monday, the international legal order was caught in the crossfire.

At the heart of the post-World War II global order — United Nations headquarters in New York — Secretary-General António Guterres told the Security Council on Saturday that U.S. and Israeli airstrikes violated international law, including the U.N. Charter. He also condemned Iran's retaliatory attacks for violating the sovereignty and territorial integrity of nations in the Mideast.

Officials in the Trump administration insist that the military campaign is a lawful measure to ensure Tehran does not build nuclear weapons. "It's a matter of global security. And to that end, the United States is taking lawful actions," Trump's U.N. ambassador, Mike Waltz, said.

Iranian Foreign Minister Abbas Araghchi wrote in a letter to the U.N. on Sunday that the killing of Supreme Leader Ayatollah Ali Khamenei "constitutes a grave and unprecedented breach of the most fundamental norms governing relations among States."

On Monday, Defense Secretary Pete Hegseth bullishly defended the U.S. military campaign. "No stupid rules of engagement, no nation building quagmire, no democracy building exercise, no politically correct wars. We fight to win and we don't waste time or lives," he said at the Pentagon.

The war with Iran comes less than two months after U.S. forces swooped into Caracas to capture former Venezuelan President Nicolás Maduro and fly him to New York to face justice.

David Crane, an American expert on international law and founding prosecutor of a United Nations court that prosecuted crimes in Sierra Leone, wrote in an analysis that U.S. attacks in Iran and Venezuela "highlight a dangerous trend: the normalization of unilateral force as a tool of foreign policy. Even when the outcome is positive, the violation of international law and constitutional limits sets a precedent that threatens global stability and undermines America's own legal foundations."

In Washington, many Democrats have called the strikes illegal. They argue that under the Constitution, only Congress has the power to declare war. They say the Trump administration failed to lay out its rationale or plan for the military strikes, and the aftermath.

Congress hurriedly scheduled a war powers debate for Monday over Trump's authority to bomb Iran.
