On June 10, 1949, petitioner commenced an action in the respondent court against Mary E. Dillon to recover money due him in the amount of $2,501. On October 1, 1949, an amendment to section 89 of the Code of Civil Procedure became effective whereby the jurisdiction of the municipal court was increased to include actions involving $3,000. When said cause came on for trial on April 3, 1950, the trial judge of his own motion transferred it to the municipal court upon the ground that respondent court did not have jurisdiction to try the same by reason of the amount involved.

*438 By the instant proceeding, petitioner seeks to annul the order- of transfer.

Respondents interposed a general demurrer to the petition, and here urge that the amendment to section 89, supra, divested respondent court of jurisdiction to try the action which involved less than $3,000.

Petitioner maintains that the jurisdiction of the superior court to try eases pending before it was not affected by the amendment, and relies upon the rule that a statute is not retroactive in operation unless the legislative intent to the contrary is clearly expressed.

There is nothing in the section here under consideration which discloses any intent to make it retrospective in its scope.

The identical question was before the court in Architectural Tile Co. v. Superior Court, 108 Cal.App. 369, 371 [ 291 P. 586 ], after the 1929 amendment to the Municipal Court Act became effective giving such court exclusive jurisdiction of “ (1) All eases at law in which the demand, exclusive of interest, or the value of the property in controversy, amounts to two thousand dollars, or less.”

It was there held that in eases of statutory change of jurisdiction, in the absence of a clearly expressed intention to the contrary, every statute will be held to operate prospectively rather than retrospectively. “It is much more reasonable and logical to assume that the legislature intended that the statute should have no effect upon pending litigation than to indulge in the presumption that they intended to deprive those litigants of their remedies whose actions were filed and against which the statute of limitations would have run except for their prior commencement. ’ ’

A court which had jurisdiction of an action when commenced does not lose that jurisdiction by a subsequent change of law cutting down its jurisdiction. (Berg v. Traeger, 210 Cal. 323 [ 292 P. 495 ]; Wheaton v. Superior Court, 108 Cal.App. 702 [ 292 P. 499 ].

In Berg v. Traeger, supra, the Supreme Court construed an amendment to the Municipal Court Act effective August 14,1929, as having the effect “of depriving the District Courts of Appeal of jurisdiction over appeals from the superior courts in any action within the jurisdiction of the municipal courts; but at the time the amendment became effective there were pending and undetermined before the several divisions of the District Courts of Appeal many appeals from the judgments of the municipal courts, and it therefore became necessary to *439 determine what effect, if any, the change of jurisdiction resulting from said amendment had upon appeals duly perfected prior thereto. . . .

Again in People v. Allied, Architects’ Assn., 201 Cal. 428, 437 [ 257 P, 511 ], the rule regarding retroactive construction is thus stated: “No statute or constitutional provision shall be so construed as to give it retroactive effect, to divest individuals of rights vested previous to its passage, or to affect pending litigation, unless such intent is expressly declared or necessarily implied in the language of the provision to be construed.”

For the reasons stated, the order transferring the instant action to the municipal court is annulled.
