The former `Two and a Half Men` star has been accused of destroying a planned reality TV project about himself and his family by a television producer working with his estranged uncle, Joe Estevez.
Ed Meyer claims the 45-year-old star conspired to intentionally interfere with contractual relations and alleges his parents, `West Wing` star Martin Sheen and his wife Janet, acted as "co-conspirators" in killing the programme.
However, they were not named as co-defendants.
The suit - which was filed in Los Angeles County Superior Court on 29.03.11 and used Charlie`s birth name Carlos Irwin Estevez - claims: "Starting on January 4, 2010, Defendant Carlos Irwin Estevez, along with co-conspirators Martin Sheen and Janet Sheen, all non-parties to the Reality Show deal, did internationally and tortuously: threaten, interfere with and restrain, and also conspire to: threaten, interfere with and restrain the Plaintiff`s reality television project starring their relative Joe Estevez, titled: `About The Sheens` aka `BeingSheen` aka `Sheen Reality,` thus destroying the contractual relationships and damaging the Plaintiff Ed Meyer."
Ed is seeking at least $20 million in damages "for the outrageous tortuous conduct" of Charlie.
Earlier this month, it was revealed Charlie is suing `Two and a Half Men` producer Chuck Lorre for $100 million, claiming he was unfairly dismissed from the show.
