This is а proceeding to review an order of the Industrial Accident Commission denying an application for an adjustment of liability as between two insurance carriers furnishing workmen’s compensation coverage for a general and special employer respectively.
There is no dispute as to the facts upon which this proceeding is predicated. An employee sustained injury in the course of his employment and was given an award. The general employer’s carrier was Central Surety and Insurance Corporation, which received all compensation insurance premiums based on the earnings of said employee. The petitioner, State Compensation Insurance Fund, was the carrier for the special employer, whose payroll report did not include the injured workman’s pay and whose corresponding premium payments to its carrier therefore did not cover this item. Upon authority of
American Motorists Insurance Co.
v.
Industrial Acc. Com.,
8 Cal (2d) 585 [
It is our opinion that the commission properly concluded that it is without jurisdiction to adjudicate a supplemental controversy involving rights of contribution and reimbursement between two insurance carriers jointly and severally responsible for the payment of a compensation award.
It is well settled that' the Industrial Accident Commission is a tribunal of limited jurisdiction, with no powers beyond those conferred upon it by section 21 of article XX of the state Constitution and the provisions of the Workmen’s Compensation, Insurance and Safety Act, now codified in the Labor Code. (§§ 3201 et seq.) That part of the section of the Constitution applicable to the consideration of the present situation reаds as follows: “The legislature is hereby expressly vested with plenary power ... to create, and enforce a complete system of workmen’s compensation, by appropriate legislation, and in that behalf to create and enforce a liability on the part of any or all persons to compensate any or all of their workmen for injury or disability, and their dependents for death incurred or sustained by the said workmen in the course of their employment, irrespective of the fault of any party. A complete system of workmen’s compensation includes . . . full provision for adequate insurance coverage against liability to pay or furnish compensation; full provision for regulating such insurance coverage in all its aspects . . . full provision fоr otherwise securing the payment of compensation; and full provision for vesting power, authority and jurisdiction in an administrative body with all the requisite governmental functions to determine any dispute or matter arising under such legislation, to the end that the administration of such legislation shall accomplish substantial *267 justice in all cases expeditiously, inexpensively, and without encumbrance of аny character....” Under this grant of power the Legislature created the Industrial Accident Commission and vested it with exclusive jurisdiction over all proceedings “(a) For the recovery of compensation, or concerning any right or liability arising out of or incidental thereto, (b) For the enforcement against the employer or an insurer of any liability for compensation imposed uрon him by this division [of the Labor Code] in favor of the injured employee, his dependents, or any third person. ...” (Labor Code, § 5300.)
While petitioner concedes that the jurisdiction of the commission is limited to the settlement of disputes arising out of the relationship of the employer to his employee, it urges that once this status is established the commission has judicial power to determine any controversy whatsoever that may develop between parties in interest respecting the compensation awarded. Upon this basis the petitioner contends that its application for an adjustment of its obligation to make compensation payments falls within the scope and intent of the above quoted language of the constitutional provision referable to the insurance features of the “system of workmen’s compensation” and the legislative enactment adopted in pursuance thereof. In support of its argument the petitioner first cites several decisions of this court wherein it was held that in determining the liability of an insurance carrier for compensation to an injured employee, the commission had the power to determine all issues of law and fact upon which the liability of the insurance carrier depended.

v.
Industrial Acc. Com.,
Closely analogous in legal principle to the present situation is the decision in
United States F. & G. Co.
v.
Superior Court,
Nor is the petitioner’s position strengthened by its reference to the following general and special employment cases involving the commission’s exercise of jurisdiction over questions of liability of the respective insurance carriers as to compensation coverage. Preliminarily it should be nоted that in each of these instances the proceeding was instituted by the employee or his dependent and the insurance issue arose in the course of the commission’s
measurement of the rights of the claimant
against the joint employers and the insurance carriers which stood in privity with them. The first of these eases is
Federal Mutual Liability Ins. Co.
v.
Industrial Acc. Com.,
Then in
American Motorists Insurance Co.
v.
Industrial Acc. Com.,
8 Cal. (2d) 585 [
This principle of the American Motorists’ decision was reiterated in a companion case,

*271
nity Co.
v.
Industrial Acc. Com.,
8 Cal. (2d) 589 [
Thus again is recognized the exclusive jurisdiction of the cоmmission to determine any issues related to the enforcement of Viability against the insurance carriers for the payment of compensation to the employee, and accordingly the objection of one joint obligor to the erroneous discharge of *272 the other is properly raised in that forum as a protective measure in the event it decides to invoke the оrdinary process of the courts in the establishment of any claim for contribution or reimbursement by reason of its obligation to satisfy the industrial award. However, no more under the theory of the Federal Mutual Liability Ins. Co. case than under the reasoning of the two later cases was the commission empowered to make an independent adjustment of any equities between the insurance carriers by an adjudication separate and apart from an award in favor of the employee or those asserting his rights. The fundamental object of the “system of workmen’s compensation” established in this state is the provision of a means for the prompt settlement of the employee’s claim against his employer or the responsible insurance carrier. The dispositiоn of disputes between insurance carriers independent of the enforcement of the liability of the employer to his employee is plainly not within the jurisdiction of a tribunal created for the purpose of affording compensation benefits to workmen for injuries sustained in their industrial employment. To extend the commission’s jurisdiction to include such extraneous and collateral сontroversies not only would delay and impede the efficacious settlement of employer-employee claims, but likewise would be wholly at variance with the declared social public policy of. this state to accomplish substantial justice in all cases of the specified class “expeditiously, inexpensively, and without encumbrance of any character. ’ ’ It therefore follows that the adjustment of petitioner’s obligation is beyond the judicial power conferred upon the Industrial Accident Commission by the constitutional provision and the pertinent legislation enacted thereunder, as above noted, and that such claim for reimbursement is a proper matter for litigation through an “independent suit” in the regularly constituted courts. (Const., art. VI, § 1.)
The order is affirmed.
