'NCIS' creator Don Bellisario is suing CBS for not including him in the creation of the now-franchise's successful spin-off, 'NCIS: Los Angeles.'

Although Bellisario was fired from the show after season 4 when star Mark Harmon threatened to leave, Deadline reports Bellisario is saying that the network was still contractually obligated to include him in the spinoff show.

The network has countered via a statement to Entertainment Weekly, saying "Don Bellisario has no rights to what he is claiming in this suit. The contract is clear, the facts are undeniable and the courts won't need Naval intelligence to conclude that the case has no merit. We continue to honor all of our obligations to Mr. Bellisario under the actual agreement."
