Is there any case law or case law that supports a claim for declaratory relief?

^3. Although Linares asserts in his opening brief that the trial court erred in sustaining the demurrer with respect to his claim for declaratory relief, he does not provide any argument or analysis as to why the court erred. Accordingly, we need not address this contention: "'Where a point is merely asserted by counsel without any argument of or authority for its proposition, it is deemed to be without foundation and requires no discussion.'
