This is an appeal by plaintiff from a judgment of the Municipal Court of the Long Beach Judicial District dismissing its action. The judgment was entered following an order sustaining defendant’s demurrer to the first amended complaint without leave to amend. The Appellate Department of the Superior Court for Los Angeles County-reversed the judgment with directions and, on its own motion certified to this court, pursuant to rule 63, California Rules of Court, that a transfer appears necessary to settle an important question of law. We transferred the case for that purpose.

The question of law to be settled is: Does a joint payee of a check have a cause of action against a collecting bank which pays a check payable to joint payee signing his own name and forging that of the other joint payee? The appellate department answered this question in the affirmative for the reasons set forth in the opinion prepared by that court by Judge Aiso, in which Judge Meyers concurred.

We believe that the decision of the appellate department is correct for the reasons stated in Judge Aiso’s opinion, and now adopt that opinion as the opinion of this court. It reads as follows:

For the reasons stated in the foregoing opinion, the judgment is reversed with directions to the trial court to overrule the general demurrers and to rule on the points raised by the special demurrers.

Appellant to recover its costs on appeal.

Kaus, P. J., and Hufstedler, J., concurred.
