OPINION OF THE COURT
While this action was pending in Supreme Court, the Public Service Commission (PSC) conducted a public hearing and issued a determination purporting to resolve the underlying controversy in plaintiffs favor. The primary question presented by this appeal is whether, pursuant to principles of issue preсlusion, the PSC’s determination is binding upon defendant in this action. We hold that under the circumstances presented here, unlike those in Allied Chem. v Niag
Plaintiff Staatsburg Water Company is a public utility corporation which supplies water to customers in parts of Dutchess County, including the Village of Staatsburg. Its activities, including the rates charged, are regulated by the Public Service Commission, which appears in this appeal as amicus curiae. Among plaintiff’s customers is the defendant, Staatsburg Fire District, to whom the Water Company supplies water for public fire protection through a number of fire hydrants. Plaintiff charges for this service based on a fixed annual rate per hydrant.
Since January 1, 1982, defendant has refused to pay plaintiff for this service, complaining that the service was inadequate due to malfunctioning hydrants and insufficient watеr pressure. As a result, plaintiff experienced a revenue deficiency and, in November 1983, sought permission from the PSC to assess its other customers a surcharge to make up for defendant’s nonpayment. In an order issued July 31,1984, the PSC authorized a temporary increase but withheld a final determinаtion regarding the proposed surcharge until plaintiff demonstrated that it had taken "all necessary and practicable steps, which may include the initiation of legal action, to secure payment from the Fire District.”
Accordingly, plaintiff commenced this action in Supreme Court, sеeking to recover the unpaid public fire protection charges. Defendant answered with allegations that the service provided by plaintiff was inadequate, and plaintiff, in turn, moved for summary judgment on the ground that the PSC’s July 31 order had resolved the adequacy-of-service issue in plaintiff’s favor. Supreme Court denied the motion, noting that the PSC had not determined the merits of defendant’s claim.
Meanwhile, and on March 27, 1985, plaintiff again filed for approval of a surcharge to make up for the lost revenues resulting from defendant’s continued nonpayment. In light of Supreme Court’s decisiоn, however, the PSC ordered that, before considering the surcharge proposal, it would initiate a formal investigation to determine whether plaintiff’s fire protection service was adequate and whether defendant was justified in withholding payment. A public hearing was scheduled and all interested parties, including defendant, were invited to participate. Defendant’s attorney appeared at the
Following the hearing, the PSC determined, in essence, that the servicе supplied by plaintiff was adequate and that defendant was not justified in withholding payment. The PSC again reserved decision on plaintiff’s request for a surcharge until after plaintiff sought recovery from defendant through litigation, a task which, the PSC opined, should be "facilitated” by its findings. Armed with this determination, plaintiff rеturned to Supreme Court, moved to amend the ad damnum clause in the complaint and renewed its motion for summary judgment, contending that the PSC’s finding was binding on the defendant. Supreme Court denied the motion to amend the complaint and, refusing to give collateral estoppel effect to thе PSC’s determination, denied the motion for summary judgment.
The Appellate Division reversed and granted both the motion to amend the ad damnum clause and the motion for summary judgment. Relying primarily on Ryan v New York Tel. Co. (
This convolutеd procedural background gives rise to a straightforward question: Should the PSC’s determination that plaintiff’s service to defendant was adequate be binding on defendant in this litigation? Plaintiff’s primary contention is that the doctrine of collateral estoppel precludes relitigation of the issue.
The relevant principles may be quickly restated. Collateral estoppel, or issue preclusion, may be invoked in a subsequent action or proceeding to prevent a party from relitigating an issue decided against that party in a prior adjudication (Ryan v New York Tel. Co., supra, at 500; Schwartz v Public Adm’r,
In addition, we have consistently emphasized that these principles are not to be mechanically applied as a mere checklist. Collateral estoppel is an elastic doctrine and the enumeration of these elements is intended as a framework, rather than a substitute, for analysis. For example, the question whether a party had a full and fair opportunity to contest the prior decision is not answered simply by reference to the procedural benefits available in the first forum or by a conclusion that the requirements of due process were satisfied (see, Gilberg v Barbieri,
In the end, the fundamental inquiry is whether relitigation should be permitted in a particular case in light of what are often competing policy considerations, including fairness to the parties, conservation of the resources of the court and the litigants, and the societal interests in consistent and accurate results. No rigid rules are possible, because even these factors may vary in relative importance depending on the nature of the proсeedings (see, Gilberg v Barbieri, supra, at 291-292; People v Berkowitz,
With these principles in mind, we conclude that the proceeding which led to the PSC’s determination suffers from a number of defects which, in combination, deprive it of preclusive effect. These defects all spring from the fact that the PSC’s finding was, in essence, an unsolicited advisory oрinion
As a result, defendant was not, in the true sense of the word, a party to the PSC proceeding — a basic prerequisite for application of the doctrine (see, Liss v Trans Auto Sys.,
Here, however, the hearing was initiated on the PSC’s own motion. The PSC is, of course, authorized to initiate investigations into the "methods employed in furnishing [water] service” and, following such an investigation and a hearing, may order "such improvement in the supply or distribution of water, or in the methods employed * * * as will in its judgment be adequate, just and reasonable” (Public Service Law §§ 89-i, 89-j). But nothing in this grant of authority suggests that, at least in the absence of a complaint filed by a customer, the PSC has authority to adjudicate payment disputes between the utility and its customers, or to hale customers before its tribunals for that purpose. As the PSC itself recognized in both of its orders, it had no power to compel defendant to pay for the water service; plaintiff was, in effect, directed to Supreme Court for that relief. In these circumstances, because the outcome of the hearing had no direct consequences for defendant, it cannot be said that defendant was a party to the PSC proceeding. At most, it was an interested, albeit unwilling, participant in a public investigation of the Water Company’s practices.
Similarly, the lack of any direсt stake in the outcome of the proceeding left defendant with little incentive to fully litigate the issue. Thus, although defendant was granted the opportunity to participate, this did not necessarily amount to a full and fair opportunity to contest the determination. It is urged, nonetheless, that suffiсient incentive was supplied by the potential collateral estoppel effect of the PSC’s determination. We have recognized that the foreseeability of future
In addition, the absence of immediate consequences for defendant in the PSC proceeding calls into question whether the PSC determination was made in the context of an adjudicatory proceeding (see, Allied Chem. v Niagara Mohawk Power Corp., supra). The term "adjudicatory”, among other things, suggests at least that the proceeding will result in a "determination of the legal rights, duties, or privileges” of the partiеs (State Administrative Procedure Act § 102 [3]). Here, the PSC’s determination did not lead to any order, judgment, decree or other pronouncement fixing such rights, duties or obligations.
The point may be best illustrated by contrasting the cases in which we have given preclusive effect to nonjudicial determinations. For example, in Ryan v New York Tel. Co. (
Notwithstanding these defects, plaintiff and the PSC urge that preclusion is warranted because, under the doctrine
Notably, however, neither plaintiff nor defendant requested the court to refer any issues in this case to the PSC for resolution. Thus, this appeal does not require us to decide whether such an application should have been granted and we express no view on that question. Nor does the doctrine bolster plaintiffs collateral estoppel argument. Even assuming that the doctrine of primary jurisdiction is applicable because the PSC has special competence to decide the question, the barriers to apрlication of issue preclusion remain. The competence or expertness of the tribunal does not neutralize the defects that we have identified and, in the absence of a reference of the issue to the agency by the court, the doctrine of primary jurisdiction doеs not provide an independent basis for giving the determination binding effect in this litigation.
For all of these reasons, we conclude that the PSC’s determination is not entitled to preclusive effect and that, therefore, plaintiff’s motion for summary judgment should not have been granted. However, the Appellate Division did not abuse its discretion in allowing plaintiff to amend the ad damnum clause of its complaint (see, Loomis v Civetta Corinno Constr. Corp.,
Accordingly, the order of the Appellate Division should be
