Does a decision that the Superior Court has no jurisdiction to dismiss a case solely for lack of jurisdiction constitute a decision on the merits for res judicata purposes?

Maddern v. Superior Court (1972) 22 Cal.App.3d 998, 10041005, 99 Cal.Rptr. 832 [reiterating that a determination that the court has no jurisdiction to act is not a decision on the merits] are distinguishable. In those cases, the courts recognized that dismissing a case solely for lack of jurisdiction does not amount to a decision on the merits for res judicata purposes; as set forth above, that is not what occurred here.

Both the Mission litigation and the instant case revolve around the same claim.
