sponsibility in this case is not to question Illinois law but simply to follow it.
Libman’s attempts to distinguish Doyle are unconvincing. It claims that this case is different from Doyle because there the employer had only made an offer to settle the compensation claim whereas here the compensation claim has been settled and Mason has executed a release. Under the reasoning in Doyle, however, this difference is insignificant because the release in the worker’s compensation claim would merely provide a defense that, like section 5(a), would not preclude Libman from being “subject to liability in tort” within the meaning of the Illinois Contribution Act. Moreover, the Illinois Supreme Court itself apparently thought the difference unimportant because it decided Doyle without knowing the “status or disposition” of the worker’s compensation proceedings that had been brought in that case. Doyle, 101 Ill.2d at 5, 77 Ill.Dec. at 761, 461 N.E.2d at 384. We conclude that Doyle allows Dal Maschio’s claim against Libman for contribution because Libman is “subject to liability in tort” within the meaning of the Illinois Contribution Act.
Libman also submits that the $280,-000 judgment entered in favor of Dal Maschio and against Libman should have been amended to read that “judgment was entered in favor of Dal Maschio for such sums that Dal Maschio paid to the plaintiff in excess of Five Hundred Twenty Thousand Dollars *” (Br. 30). We disagree. Although the amounts may change after a new trial, the same issue will presumably arise after the new trial, and therefore we will address Libman’s argument prior to remand.
The language of the Illinois Contribution Act obviates any need to amend the language of the judgment in order to secure the outcome Libman seeks. The Contribution Act clearly states:
The right to contribution exists only in favor of a tortfeasor who has paid more than his pro rata share of the common liability, and his total recovery is limited to the amount paid by him in excess of his pro rata share. No tortfeasor is liable to make contribution beyond his own pro rata share of the common liability.
Ill.Rev.Stat., ch. 70, ¶ 302(b) (emphasis added). “According to the language of the Act itself, a tortfeasor is entitled to contribution only when he has paid an amount in excess of his pro rata share of liability.” Victory Memorial Hospital Assoc, v. Schmidt, Garden & Erickson, 158 Ill.App.3d 931, 110 Ill.Dec. 776, 511 N.E.2d 953 (2d Dist.1987). As a result of the explicit language of the Act, the qualification that Dal Maschio is not entitled to contribution until it has paid Mason more than the amount determined at the new trial to be its pro rata share is implicit in the judgment against Libman. As such, the judgment need not be amended to state the obvious explicitly.
In
Stephens v. McBride the Illinois Appéllate Court differentiated between the ability to assert a cause of action under the Contribution Act and the accrual of the right to contribution under the Act. The court noted that while “the cause of action can be asserted ‘before ... payment, by counterclaiming or by third-party action,’ ” “[ujnder the Contribution Act the right of contribution accrues upon the tortfeasor’s payment of ‘more than his pro rata share.’ ”
Stephens v. McBride, 105 Ill.App.3d 880, 887, 61 Ill.Dec. 673, 678, 435 N.E.2d 162, 167 (1st Dist. 1982), affirmed,
97 Ill.2d 515, 74 Ill.Dec. 24 (1983) 455 N.E.2d 54 (citing Ill.Rev.Stat., ch. 70, HIT 305, 302(b)). A further articulation of this distinction appears in
Verson Allsteel Press v. Major Spring & Manufacturing Co., 105 Ill.App.3d 419, 61 Ill.Dec. 303, 434 N.E.2d 456 (1st Dist. 1982). The court in
Verson cited the following as an “accurate enunciation of the law” of Illinois:
The right of contribution between joint tortfeasors arises at the time of the concurring negligent acts. Until one of the joint tortfeasors pays more than his por-tionate share of the underlying claim, the right remains contingent, subordinate and inchoate.
