OPINION OF THE COURT ■
This appeal from an order of the district court dismissing a complaint brought under 42 U.S.C. §§ 1983 and 1985, and permanently enjoining appellant from instituting proceedings against appellees and those in privity with them, presents questions of res judicata and collateral estoppel.
On January 3, 1968, appellant brought suit against John Ellmyer, Lillian Apel, Louis La Plaga and Marie Keller, over an incident involving a $55.00 check.
1
On November 8, 1968, appellant requested that the suit be withdrawn. The district court granted the motion and dismissed with prejudice. Subsequently, on May 11, 1970, appellant moved to reopen the judgment. The motion was denied and we affirmed. Gambocz v. Ellmyer,
*840
Dismissal with prejudice constitutes an adjudication of the merits as fully and completely as if the order had been entered after trial. Lawlor v. National Screen Service Corp.,
As to the defendants Yelencsics, Ferenczi, and the township,
3
none of whom were parties to the first action, we must consider the application
*841
of the doctrine first enunciated by this court in Bruszewski v. United States,
In the application of
the.Bruszewski
doctrine, however, it is important that we be governed by the principle of the law rather than by the nomenclature affixed to it. Thus, the doctrine is sometimes called “collateral estoppel,” see Provident Tradesmens Bank & Trust Co. v. Lumbermens Mutual Casualty Co.,
Thus, under the doctrine of res judicata, a judgment “on the merits” in a prior suit involving the same parties or their privies bars a second suit based on the same cause of action. Under the doctrine of collateral estoppel, on the other hand, such a judgment precludes relitigation of issues actually litigated and determined in the prior suit, regardless of whether it was based on the same cause of action as the second suit.
Lawlor v. National Screen Service Corp.,
supra,
The above distinction becomes important in this case. The cause of action was terminated in the first proceedings, and, therefore, the principle of
res judicata
would apply in favor of the original defendants and those new defendants encompassed by the
Bruszewski
rule. On
*842
the other hand, the orthodox doctrine of collateral estoppel described by Chief Justice Warren in
Lawlor
is inapplicable here because the first “judgment was unaccompanied by findings and hence did not bind the parties on any issue.” Lawlor v. National Screen Service Corp.,
supra,
We previously determined that the essential allegations of the second complaint parallel those of the first. Moreover, what was averred in the original action was a conspiracy participated in by named individuals, and the sole material change in the later suit was the addition of certain defendants, some of whom had been named in the original complaint as participating in the conspiracy but had not been named as parties defendant at that time. We conclude that the relationship of the additional parties to the second complaint was so close to parties to the first that the second complaint was merely a repetition of the first cause of action and, therefore, it is barred by application of the Bruszewski doctrine.
The court below granted appellee's request for a permanent injunction restraining appellant from instituting proceedings against appellees and their privies based upon the operative facts alleged in the complaint. Injunctive relief was a proper remedy under the circumstances of this case. See Root v. Woolworth,
The judgment of the district court will be affirmed.
Notes
. Gambocz is an insurance broker or agent; Apel is court clerk for Edison Municipal Court; Ellmyer and La Plaga are police officers. Gambocz had given Keller a check which was returned for insufficient funds. Thereafter Keller signed a criminal complaint against Gambocz alleging the worthless check. Yelencsics was Gambocz’s political opponent in a mayoralty contest in Edison, New Jersey. Ferenozi was his campaign manager. The gravamen of Gambocz’s complaint is that all the defendants conspired against him to bring the worthless check charge for the purpose of harming him “in his standing in the community, in business relations, [and] opportunity to run for political office.” An action for abuse of process, brought in the state court system, was resolved in defendants’ favor. Gambocz v. Apel,
. The essential allegations of the second complaint may be compared with those of the first complaint which was dismissed with prejudice:

. A municipality is immune from suit under 42 U.S.C. § 1983. United States ex rel. Gittlemacker v. County of Philadelphia,
. Where one or both suits have been brought under federal diversity jurisdiction, the collateral estoppel and
res judicata
laws of the forum state (s) may become applicable through Erie R. R. v. Tompkins,
. The majority in
Nickerson
recognized that Judge Hastie’s view was the general rule, but concluded that it was not applicable to patent cases: “We continue to believe that such change as may be desirable in this exception in_patent cases to the general rule of collateral estoppel should be made ... by the Supreme Court itself. . . . ”
