President Donald Trump does not have to disclose his tax returns to appear as a candidate on California’s primary ballot next spring, the state Supreme Court ruled unanimously Thursday.

The law, the first of its kind in the nation and aimed squarely at Trump, violates a specification of the state constitution calling for an “inclusive open presidential primary ballot,” the court said.

“Ultimately, it is the voters who must decide whether the refusal of a ‘recognized candidate throughout the nation or throughout California for the office of President of the United States’ to make such information available to the public will have consequences at the ballot box,” Chief Justice Tani Cantil-Sakauye wrote in the 7-0 decision.

Trump has broken with tradition among presidential candidates by refusing to disclose his financial information.

A U.S. judge had temporarily blocked the state law in response to a different lawsuit, and the high court ruled quickly because the deadline to file tax returns to get on the primary ballot is next week.

The state Republican Party and chairwoman Jessica Millan Patterson challenged the bill signed into law this year by Democratic Gov. Gavin Newsom because it singled out Trump.
