The actor filed a $100 million (£66.7 million) lawsuit earlier this month (Mar11) after he was fired from the show and named Warner Bros. executives and show creator Chuck Lorre in court papers.
As well as demanding the cash he would have earned from the eight episodes producers cancelled at the end of last month (Feb11) - following Sheen's radio attack on Lorre - the actor is also asking the TV executives to pay the crew's full salary. Many have been left out of work and struggling financially because of the season cancellation.
However, Sheen may not get the day in court he craves after the private-resolution company JAMS decided on Wednesday (16Mar11) that Sheen's grievances are a matter for third-party arbitration.
And Sheen's lawyer, Marty Singer, is not happy with the decision, telling The Hollywood Reporter, ""The subject matter of this dispute is not just Charlie and Chuck Lorre. Our lawsuit involves claims over the entire cast and crew, and there is no right to arbitrate with them.
""We still feel we will prevail because the facts and law are 100 percent in our favour. I can understand why Chuck Lorre wants to keep this in a secret tribunal. When the facts come out they will show that he and Warner Bros. had absolutely no basis to terminate my client.""
Lorre's lawyer, on the other hand, is happy with JAMS call for arbitration, telling E! News, ""Despite Mr. Sheen's objections JAMS made the correct decision.""
