Nursing home employees who deliberately and repeatedly refer to transgender patients with a name or pronoun different from the one they prefer can be charged with a crime under state law, the California Supreme Court ruled unanimously Thursday, overturning a lower-court ruling that had declared the law unconstitutional.

Under the law, browsers like Google’s Chrome and Microsoft’s Edge will have until the beginning of 2027 to create a way for consumers to select the signal. Combined with recent changes from other states, the new law could be a tipping point in how web traffic is treated in the United States.

The ruling, due by next summer, will determine not only the validity of Trump’s multibillion-dollar tariffs and their impact on businesses and consumers, but also the willingness of the court to apply its restrictions on executive authority to presidents of both parties.

California Chief Justice Patricia Guerrero began the court’s oral argument session Tuesday with a tribute to former Justice Joseph Grodin, who died in April at age 94.
