Sheen's contract with Warner Bros. Television has a valid arbitration clause, Los Angeles Superior Court Judge Allan Goodman wrote in a 21-page ruling. The decision will dampen publicity about the case, which Sheen filed on March 10 - days after he was fired from his starring role on television's top-rated comedy.
The ruling applies to Sheen's allegations against "Men" executive producer Chuck Lorre, whose contract with Warner Bros. also has an arbitration clause.
Sheen had requested the case be heard in public court, and a judge heard arguments on the issue in April.
But Goodman said in his ruling that Sheen was represented by competent attorneys when he signed his contract requiring any disputes to be handled through private arbitration.
The studio cited Sheen's bizarre behavior in interviews and his criticism of Lorre as reasons for the actor's firing.
Sheen's role has been eliminated from the show and Ashton Kutcher will appear next season.
Sheen's spokesman Larry Solters declined comment in an email. A phone message to Sheen's attorney, Marty Singer, was not immediately returned.
"We're very gratified by the court's ruling enforcing the parties' arbitration agreement," Warner Bros. said in a statement.
Lorre's attorney, Howard Weitzman, also welcomed the ruling.
"This matter will now proceed in an orderly fashion as the parties agreed to," Weitzman wrote in an email.
