The appellants brought this action in the district court seeking damages under 42 U.S.C. § 1983 (Supp. IV 1980) for an alleged violation of their civil rights. The district court dismissed their suit on the basis of res judicata, finding that the appellants’ earlier state court suit, which stemmed from the same set of facts and in which they sought and won injunctive relief, barred them from later bringing this suit in federal court. On the appeal from that dismissal, we affirm the decision of the district court. 1
In September of 1978, the appellants obtained a building permit from the appellee, the city of Evanston, Illinois, to build a residential development on a parcel of land in Evanston. Some time later, after a substantial amount of construction had been done, Evanston officials determined that the building permit had been issued erroneously, and that the appellants’ development would violate applicable zoning requirements. Subsequently, Evanston’s Zoning Board of Appeals voted to revoke the building permit, and the city halted construction. The appellants then filed suit in the Chancery Division of the Circuit Court of Cook County, claiming that Evanston was es-topped to revoke the building permit, and seeking to enjoin Evanston from interfering with the completion of their project. The circuit court granted the appellants injunctive relief, noting that they had incurred nearly a million dollars in expenses in reliance on the permit. However, the court conditioned its injunction upon the performance of certain actions by the appellants.
The circuit court’s order was not stayed pending appeal, and the appellants resumed construction of their development. A dispute arose concerning some aspects of the appellants’ compliance with the conditions of the circuit court’s order, and Evanston again halted work at the construction site. The appellants then went back to the state circuit court to petition for a rule to show cause. After a hearing, the state court denied the appellants’ petition.
On December 8, 1980, the Illinois Appellate Court affirmed the circuit court’s order granting the appellants injunctive relief.
Hagee v. City of Evanston,
The district court first dismissed the appellants’ complaint for failure to state a cause of action for relief under section 1983.
Hagee v. City of Evanston,
The district court found that the appellants’ present suit was barred by res judicata because the appellants could have raised their current claims in their earlier state court suit but failed to do so. It is a well-established rule that res judicata bars parties or their privies from litigating not only matters that in fact were raised and decided in an earlier suit involving the same cause of action and the same parties, but also all other matters that could have been raised in the earlier suit.
Lee v. City of Peoria,
The appellants correctly point out that under 28 U.S.C. § 1738 (1976),

this court must apply the res judicata law of Illinois in determining the preclusive effect of a judgment rendered by an Illinois court. In
Allen v. McCurry,
As we have indicated, the appellants frame the main question on this appeal as whether their earlier state court suit and their present suit involve the same cause of action under Illinois law, for purposes of applying the doctrine of res judicata. The Illinois intermediate appellate courts have produced a wealth of cases on the question of what constitutes a cause of action, but they have not spoken with one voice. Our review of Illinois case law reveals many different formulations of the test to determine whether two suits involve the same
In the first group of cases, the courts have approached the task of deciding whether two suits involve the same cause of action by looking at the proof required in each suit. This “proof” approach has been stated in numerous ways. For example, one oft-cited standard is whether the same evidence would sustain both actions.
See, e.g., Mendelson v. Lillard,
In the other group of Illinois cases dealing with the res judicata doctrine, the courts have taken a “transactional” approach to identifying a cause of action.
5
A court employing a transactional approach will focus not on the type of proof required in each suit, but on the factual setting in which each suit arises. If both suits arise from the same transaction, incident or factual situation, res judicata generally will bar the second suit. In
Baird & Warner, Inc. v. Addison Industrial Park, Inc.,
These two approaches to identifying a cause of action for purposes of res judicata can lead to different results. Which of the two approaches is mandated under Illinois law is not immediately discernible as the Illinois Supreme Court has not explicitly adopted one approach over the other. With the intermediate Illinois appellate decisions not consistent in their treatment of this area of the law, and in the absence of specific direction from the state’s highest court, we deem it appropriate under section 1738 to look to the most recent pronouncements of the Illinois Supreme Court with regard to the policies behind the res judicata doctrine and the scope of that doctrine in deciding whether the appellants’ suit should be barred.
[T]he conclusiveness of the judgment in such case [the prior action] extends not only to matters actually determined, but also to other matters which could properly have been raised and determined therein. This rule applies to every question relevant to and falling within the purview of the original action, in respect to matters of both claim or grounds of recovery, and defense, which could have been presented by the exercise of due diligence.
Hughey v. Industrial Commission,
The principle that res judicata extends to all matters within the purview of the original action, whether or not they were actually raised, is tantamount to a rule requiring parties to consolidate all closely related matters into one suit.
7
As such, the principle serves well the interest of judicial economy, and thus it is at the core of the res judicata doctrine.
8
Two corollaries of that principle are also of fundamental importance to Illinois's res judicata doctrine. First is the rule that a party may not maintain two suits based on the same set of facts by the simple expediency of limiting the theories of recovery advanced in the first.
See Hughey v. Industrial Commission,
It is on the basis of these rules that we find the appellants’ present suit barred. A close examination of the appellants’ two suits reveals that their current suit is in effect a reincarnation of their first suit, brought under a different legal theory and requesting a different kind of relief. The appellants’ first suit was brought to enjoin the city of Evanston from preventing the completion of the appel
Notes
. The appellee has argued that if we do not uphold the district court’s ruling on res judicata grounds, we nevertheless should affirm the dismissal of the appellants’ suit, on the grounds that the appellants have failed to state a cause of action under § 1983. Because we find the appellants’ suit to be barred by res judicata, we express no view on the question of whether they have stated a cause of action under § 1983.
. We note that this rule applies to civil rights actions under § 1983 as it does to other types of suits.
Lee v. City of Peoria,
. Section 1738 reads in pertinent part:
[J]udicial proceedings shall have the same full faith and credit in every court within the United States and its Territories and Possessions as they have by law or usage in the courts of such State ... from which they were taken.
. Other Illinois courts have held the test to be whether the evidence needed to sustain the second action would have sustained the first.
See, e.g., Schmitt v. Woods,
. The transactional approach is said to be the present trend among courts nationwide. See Restatement (Second) of Judgments § 24 comments a, b and c (1980).
. Other Illinois courts have also adopted a transactional approach in determining whether two suits involve the same cause of action, looking at the "operative facts” or "underlying facts” of each suit.
See Radosta v. Chrysler Corp.,
. We note that this rule is somewhat at odds with the use of a proof test to determine whether two suits involve the same cause of action. Strict application of a proof test, that is, finding one suit barred by another only if the maintenance of the suits depends on identical proof, would allow litigants to circumvent the rule requiring them to consolidate closely related matters. They could do this by altering some aspects of their basic claim from one suit to the next, thus contriving a distinction in the proof required for the maintenance of each suit and preventing the application of res judicata. Nevertheless, a few Illinois courts have applied a proof test very strictly.
See, e.g., Cranwill v. Donahue,
. The fact that only the res judicata doctrine can bar the litigation of matters that were not actually litigated in an earlier suit is one of the primary distinctions between res judicata and collateral estoppel under Illinois law.
See People v. Bone,
. We note that this is not a case involving a plaintiff who sought urgently needed temporary injunctive relief and then came to court with a claim for damages shortly thereafter as part of the same suit. Nor have the appellants claimed that they could not ask for damages in their earlier suit because damages had not yet been incurred. In fact, the appellants stated at oral argument that their failure to seek damages in state court was a matter of strategy. Apparently, the appellants thought that a request for damages would jeopardize their chances of procuring injunctive relief, which was their more immediate concern. Thus, it is clear that the appellants did have a “full and fair opportunity” to litigate their present claims in their earlier suit, a prerequisite to the application of res judicata.
Allen
v.
McCurry,
. The appellants have also argued that res judicata is inapplicable to their case because Illinois law would permit a court to try their equitable and legal claims separately. We reject this argument, because it is clear that under Illinois law an action in equity can bar a subsequent action in law, or vice versa, under the res judicata doctrine.
