A New York State court on Tuesday dismissed a defamation lawsuit filed by the re-election campaign of Donald J. Trump against The New York Times Company, ruling that an opinion essay that argued there had been a “quid pro quo” between the candidate and Russian officials before the 2016 presidential election was protected speech.

The Times published the Op-Ed, written by Max Frankel, a former executive editor of The Times who was not named as a defendant in the suit, in March 2019 under the headline “The Real Trump-Russia Quid Pro Quo.” Mr. Frankel made the case that in “an overarching deal” before the 2016 election, Russian officials would help Mr. Trump defeat Hillary Clinton in exchange for his taking U.S. foreign policy in a pro-Russia direction.

Mr. Trump’s re-election campaign, Donald J. Trump for President Inc., filed the suit in New York State Supreme Court in February 2020, alleging defamation and accusing The Times of “extreme bias against and animosity toward” the campaign.

In his decision on Tuesday, Judge James E. d’Auguste noted three reasons for dismissal. He wrote that Mr. Frankel’s commentary was “nonactionable opinion,” meaning it was constitutionally protected speech; that the Trump campaign did not have standing to sue for defamation; and that the campaign had failed to show that The Times had published the essay with “actual malice.”
