If your case as been resolved, it cannot be re-litigated, absent an order from the Appellate court for the case or issue to be remanded to the trial court. You get one "bite at the apple." In short, No, unless it is a completely different claim and set of facts you could not have brought forth the first time around.
While I am an attorney, I am not your attorney. You should always speak with your own attorney to gain full and complete legal advice.
You only get "one day" in court (trial court, another for an appeal to the Superior Court) for each transaction or occurance. Joining another claim, even under different legal theories, would not be permitted.
The above is general legal and business analysis. It is not "legal advise" but analysis, and different lawyers may analyse this matter differently, especially if there are additional facts not reflected in the question. I am not your attorney until retained by a written retainer agreement signed by both of us. I am only licensed in California.

If it the same claims based upon the same facts already decided then you cannot. If they are a set of different facts from a different incident or facts that were unknown that significantly changes the claim then those have not been decided and may be considered.
