The Supreme Court won't hear an appeal from some television networks being sued by a paranormal investigator who claims his idea was stolen and turned into the television show "Ghost Hunters."

Without comment, the court turned away an appeal from NBC Universal, Inc., Universal Television Networks and Pilgrim Films & Television, Inc.

Parapsychologist Larry Montz and producer Daena Smoller unsuccessfully shopped around an idea for a show about paranormal investigators in 1981. "Ghost Hunters" appeared on the Sci Fi Channel — now known as SyFy — in 2004.

Montz and Smoller sued in federal court. The courts threw out their copyright claims, but the 9th U.S. Circuit Court of Appeals agreed that they could sue for breach of an implied contract and breach of confidence claims.
