A federal judge has dismissed a lobbyist for the state of Qatar from a hacking lawsuit brought by Republican donor Elliott Broidy, citing jurisdiction issues, days after dismissing the Persian Gulf country from the same suit.

Mr. Broidy, who has business interests in the United Arab Emirates, has accused Nick Muzin of participating in an alleged Qatari conspiracy to steal and distribute his private emails to embarrass him, and by extension, the U.A.E. The messages detailed Mr. Broidy’s contacts with the Trump administration and the U.A.E., Qatar’s Persian Gulf rival.

Judge John F. Walter of the U.S. District Court for the Central District of California on Friday dismissed Mr. Muzin and his Washington lobbying firm, Stonington Strategies, from the suit, after concluding that the court didn’t have jurisdiction over the defendants.

Because of that, the judge said he didn’t need to rule on the merits of the case. The judge said the plaintiffs “fail to allege any facts to support” allegations that Mr. Muzin and his firm helped organize and disseminate the stolen emails and “funnel funds to others involved in the attack.”

Mr. Muzin said in a statement that he was “grateful to be dismissed from this case” and called it “a just and conclusive result.” He and Qatari representatives have previously denied any involvement in the hack.
