Is plaintiff barred by res judicata from bringing this action?

First, defendants argue plaintiff is barred by res judicata from bringing this action as he has previously filed a complaint raising this same claim, which was dismissed with prejudice for failure state a claim for which relief can be granted. The defense request the court take judicial notice of the complaint filed in Willaims v. CDCR, 2:06-cv-2903-MCE-EFB, as well as the orders dismissing that case. As these documents are part of the court's own records, and therefor subject to judicial notice, that request should be granted.
