Landing in A.B.C.G. Soup:
The Compulsory Counterclaim Trap
Wisconsin's counterclaim statute says 
counterclaims may be brought, but the supreme court in A.B.C.G. said 
counterclaims must be brought for certain claims. A rule change to 
clarify when a counterclaim is compulsory would help litigants avoid the 
soup of uncertainty.
 
by Donald Leo Bach

our client is a buyer of 
goods. The seller has 
sued your client for nonpayment. Your client reveals facts to you that 
indicate there was a mutual mistake in the formation of the contract 
justifying its rescission and return of the goods. When you advise the 
client of the availability of such claim for rescission, the client 
indicates he does not want to litigate that issue now in the pending 
lawsuit.
You check the pleading statutes to see if your client's claim has to 
be brought as part of the current action. Pleadings are controlled by 
the Wisconsin Rules of Civil Procedure, specifically by Wis. Stat. 
chapter 802, Civil Procedure - Pleadings, Motions and Pretrial Practice. 
You find a statute directly on point, namely Wis. Stat. section 
802.07(1), which states:
"802.07 Counterclaim and cross-claim. (1) Counterclaim. A defendant 
may counterclaim any claim which the defendant has against a 
plaintiff, upon which a judgment may be had in the action. A 
counterclaim may or may not diminish or defeat the recovery sought by 
the opposing party." (Emphasis added.)
The statute is clearly a permissive counterclaim statute. There is no 
language in the statute that can be fairly read in any way to compel the 
bringing of any counterclaim. The statute says to the defendant, "you 
get your day in court when and where you see fit, not in the place, the 
proceeding, or the timeframe chosen by the opponent." Therefore, it is 
crystal clear that your client does not have to bring a counterclaim for 
rescission in the current suit and that you can wait right up to the 
statute of limitation expires to file an action for rescission. 
Right?
Wrong.
You have just fallen into the A.B.C.G. compulsory 
counterclaim soup.
The A.B.C.G. Common-law Compulsory Counterclaim 
Rule
Donald Leo 
Bach, U.W. 1974, is a shareholder in DeWitt Ross & Stevens 
S.C., Madison, where he practices litigation, environmental, consumer, 
and administrative law. He is a member of the Wisconsin Judicial 
Commission, which conducts investigations for review and action by the 
Wisconsin Supreme Court regarding allegations of misconduct or permanent 
disability of a judge or court commissioner. He formerly served as chair 
of the State Bar Bench-Bar Committee and of its survey subcommittee.
 
In spite of the permissive language contained in Wis. Stat. section 
802.07, in 2005 in Menard Inc. v. Liteway Lighting 
Products,1 the Wisconsin Supreme Court 
confirmed a compulsory common-law counterclaim rule for certain claims. 
The court set forth the rule in 1994 in A.B.C.G. Enterprises Inc. v. 
First Bank Southeast N.A.2 In that 
case, A.B.C.G. Enterprises Inc. and two individuals 
("A.B.C.G.") sued First Bank Southeast. First Bank had 
previously sued A.B.C.G. in six separate foreclosure actions, all of 
which resulted in default judgments in favor of First Bank. A.B.C.G.'s 
follow-up suit asserted that First Bank's breach of the contract, 
misrepresentation, and failure to properly manage the properties that 
were the subject of First Bank's prior foreclosure actions caused 
A.B.C.G. to default. Accordingly, A.B.C.G. sought compensatory damages 
resulting from the foreclosure. The circuit court granted summary 
judgment to First Bank and dismissed A.B.C.G.'s action. The court of 
appeals affirmed. The Wisconsin Supreme Court upheld the dismissal, 
holding that "principles of res judicata [claim preclusion]3 preclude a defendant who may counterclaim in a 
prior action from bringing a subsequent action on the claim if the 
action would nullify the initial judgment or impair rights established 
in the initial action."4 Concluding that a 
favorable judgment for A.B.C.G. would undermine the previous judgments 
granted to First Bank, the supreme court affirmed the summary judgment 
dismissing A.B.C.G.'s action.5
In issuing its ruling, the supreme court relied on the common-law 
compulsory counterclaim rule as stated in the Restatement (Second) of 
Judgments section 22(2)(b) (1982):
"(2) A defendant who may interpose a claim as a counterclaim in an 
action but fails to do so is precluded, after the rendition of judgment 
in that action, from maintaining an action on the claim if ...
...
b. The relationship between the counterclaim and the plaintiff's 
claim is such that successful prosecution of the second action would 
nullify the initial judgment or would impair rights established in the 
initial action."6
The supreme court explained that section 22(2)(b) of the Restatement 
recognizes the need to preclude defendants - even in jurisdictions, like 
Wisconsin, that have a permissive counterclaim statute - from bringing a 
subsequent action that would undermine the rights established in the 
initial judgment. According to the supreme court, the rule "preserves 
the integrity and finality of judgments and the litigants' reliance on 
them."7
Observing that the claim preclusion doctrine is premised on the maxim 
that litigation must come to an end so as to ensure fairness to the 
parties and sound judicial administration, the court remarked that the 
doctrine "is applied with a broad brush so as to achieve these goals. It 
embraces not only what has been litigated in previous proceedings, but 
also extends to issues that could have been litigated."8
A.B.C.G. conceded that the doctrine of res judicata existed in 
Wisconsin. However, A.B.C.G. argued that even if its claims would 
traditionally be barred under a claim preclusion analysis, the doctrine 
was inapplicable because Wis. Stat. section 802.07(1) is a permissive 
counterclaim statute.9 A.B.C.G. argued that 
the statute's language does not require a defendant to bring any 
counterclaim; thus, to bar A.B.C.G.'s claims would transform Wisconsin's 
permissive counterclaim rule into a compulsory rule.
In response, the court acknowledged that the "general rule in 
Wisconsin is that where a defendant may interpose a counterclaim but 
fails to do so, he is not precluded from maintaining a subsequent action 
on that claim," but the court held that the rule is not absolute.10 The court said that the "better rule of law to 
apply" was section 22(2)(b) of the Restatement as a "common-law 
compulsory counterclaim" exception, finding:
"This rule preserves the integrity and finality of judgments and the 
litigants' reliance on them, by precluding a collateral attack upon a 
judgment in a subsequent proceeding when the attack would completely 
undermine the rights established in the initial judgment."11
The court summarized its holding:
"We hold that the principles of res judicata preclude a defendant who 
may counterclaim in a prior action from bringing a subsequent action on 
the claim if the action would nullify the initial judgment or impair 
rights established in the initial action."12
Wisconsin Supreme Court Reaffirmation of A.B.C.G.
Although a decade has passed since the A.B.C.G. holding, the 
issue remains contentious. In 2005 the Wisconsin Supreme Court revisited 
the matter, confirming its A.B.C.G. decision in Menard Inc. 
v. Liteway Lighting Products.13
For six years, Menard purchased lighting fixtures from Liteway. 
Menard and Liteway ended their business relationship in 1999. In 2000, 
Liteway sued and obtained a default judgment against Menard for unpaid 
invoices totalling $355,000. About eight months after the judgment was 
docketed, Menard sued Liteway for unjust enrichment and for violating 
the Uniform Commercial Code. Menard alleged that it had returned some of 
Liteway's products due to their defective condition (before Liteway 
brought suit) and that Liteway had not reimbursed Menard for the 
returns. Liteway moved for summary judgment based on claim preclusion. 
The circuit court denied summary judgment, held a trial, and granted 
Menard a $140,000 judgment against Liteway. The court of appeals 
reversed, concluding that Menard's claims were barred by claim 
preclusion, because the claims were covered under the common-law 
compulsory counterclaim rule as set forth in A.B.C.G. The 
matter was appealed to the supreme court.
The supreme court agreed with the court of appeals, holding that the 
principles of A.B.C.G. applied. In its decision, the supreme 
court again addressed and rejected the argument that the common-law 
compulsory counterclaim rule was inconsistent with Wisconsin's 
permissive counterclaim statute, Wis. Stat. section 802.07. In 
Menard, the court reaffirmed its holding in 
A.B.C.G.:
"The common-law compulsory counterclaim rule creates an exception to 
the permissive counterclaim statute and bars a subsequent action by a 
party who was a defendant in a previous suit if `a favorable judgment in 
the second action would nullify the judgment in the original action or 
impair rights established in the initial action.' The common-law 
compulsory counterclaim rule operates to `preserve[ ] the integrity and 
finality of judgments and the litigants' reliance on them, by precluding 
a collateral attack upon a judgment in a subsequent proceeding when the 
attack would completely undermine the rights established in the initial 
judgment.'"14
The court concluded that for the common-law compulsory counterclaim 
rule to apply, a court must find that: 1) all the elements of claim 
preclusion are present and 2) a judgment favorable to the plaintiff in 
the second suit would undermine the judgment or impair the established 
legal rights of the plaintiff in the initial action.15
The court decided that Menard's claims in the second suit were part 
of the same transaction as the claims in the original suit because both 
suits arose from the same "common nucleus of operative facts."16 Further, the court found that Menard's claims in 
the second suit could have been raised in the original suit.17 Accordingly, it upheld dismissal of Menard's 
action against Liteway.
Justice Crooks, in a dissent joined by Justice Butler, asserted that 
claim preclusion and A.B.C.G.'s compulsory counterclaim rule 
did not apply. As to the latter, Justice Crooks stated:
"Although the resolution of this case rests on whether there was an 
identity of claims or causes of action for purposes of claim preclusion, 
it is also necessary to highlight the majority's misinterpretation of 
Wisconsin's counterclaim statute. In Wisconsin, the joinder of 
counterclaims is permissive, not mandatory. Wisconsin Stat. section 
802.07(1) states in relevant part: `[a] defendant may 
counterclaim any claim which the defendant has against a plaintiff, upon 
which a judgment may be had in the action.' (Emphasis added.)
"I recognize, as does the majority, that this court has established a 
narrow exception to the permissive counterclaim statute. In A.B.C.G. 
Enterprises, we stated that there is a `"common-law compulsory 
counterclaim rule" which requires a defendant to counterclaim if its 
claim, when brought in a subsequent, separate action, would nullify the 
initial judgment or impair rights established in the initial action.' 
A.B.C.G. Enters., 184 Wis. 2d at 474. However, the court 
emphasized that the application of this `common-law counterclaim' rule 
is definitely an exception to the general rule and is meant to preclude 
a collateral attack when the attack would completely nullify the rights 
established in the first judgment. See id. at 476-77. 
Specifically, it stated that the rule `applies only if a 
favorable judgment in the second action would nullify the judgment in 
the original action or impair rights established in the original 
action.' Id. (emphasis added.) In this case, consistent with 
our holding in National Operating, the narrow exception should 
not be applied, because the test for its application is not met here. 
Menard's UCC and unjust enrichment claims would not nullify, but would 
merely reduce, the amount that Liteway would realize on its judgment. 
The majority opinion extends the compulsory counterclaim exception in a 
manner contrary to Wisconsin's permissive counterclaim statute, the UCC, 
and the public policy expressed by the legislature in its adoption of 
the UCC."18
The Problem and the Fix
Due to A.B.C.G. and its progeny, an unfortunate situation 
has developed in which a statute clearly says one thing and a court 
doctrine says another, thus creating a veritable trap for unwary 
practitioners. Further, although the court has said that the 
A.B.C.G. compulsory counterclaim rule covers a "narrowly 
defined class" of counterclaims,19 
ascertaining when that narrow exception applies can be difficult: not 
all counterclaims must be brought, only those that "would nullify the 
initial judgment or impair rights established in the initial 
action."20 Indeed, the Restatement notes 
that subsection (2)(b) and its comments and illustrations "represent an 
effort to articulate the basis in precedent and policy for what might be 
termed a `common-law compulsory counterclaim rule.' It is perhaps 
impossible to define the scope of this concept with precision and in any 
event the problem is one of decreasing importance with the growth of 
compulsory counterclaim statutes. ..."21
The problem can be resolved; several options are available. First, 
the Wisconsin Supreme Court22 or the 
legislature could decree that no counterclaims of any type are required 
whatsoever, that is, create an "absolutely permissive" counterclaim 
statute. However, this option would obviously undercut the doctrine of 
claim preclusion and its underlying principles and might lead to 
potentially endless and multiple litigation, gamesmanship, and 
unnecessary cost.
Second, the Wisconsin legislature or supreme court could make all 
counterclaims mandatory no matter what the nature of the counterclaim. 
However, this option would deprive defendants of the ability to choose 
the time and place for bringing their claims and would require parties 
to litigate at one time all legal disputes between them - even those 
disputes unrelated to the original claim - just because one party 
started a lawsuit.
Third, the Wisconsin Supreme Court or the legislature could codify 
A.B.C.G. as an exception to the permissive counterclaim statute 
simply by incorporating the substance of the Restatement rule section 
22(2)(b) language into Wis. Stat. section 802.07(1). Such a provision 
could read as follows:
"802.07 Counterclaim and cross-claim. (1) 
Counterclaim. A defendant shall interpose a claim as a counterclaim if 
the relationship between the counterclaim and the plaintiff's claim is 
such that successful prosecution of the claim in a subsequent action by 
the defendant would nullify the initial judgment or would impair rights 
established in the initial action. A defendant may counterclaim any 
other claim that the defendant has against a plaintiff, upon which a 
judgment may be had in the action. A counterclaim may or may not 
diminish or defeat the recovery sought by the opposing party. Except as 
prohibited by § 802.02(1m), the counterclaim may claim relief 
exceeding in amount or different in kind from that sought in the 
pleading of the opposing party."
Fourth, Wisconsin could essentially codify the finality-of-litigation 
policy underlying A.B.C.G. and Restatement 22(2)(b) and greatly 
simplify the A.B.C.G. rule by replacing Wis. Stat. section 
802.07(1) with the text of Rule 13(a)-(c) and (e)-(f) of the Federal 
Rules of Civil Procedure (modified to refer to state law) as 
follows:
"(a) Compulsory Counterclaims. A pleading shall state as a 
counterclaim any claim which at the time of serving the pleading the 
pleader has against any opposing party, if it arises out of the 
transaction or occurrence that is the subject matter of the opposing 
party's claim and does not require for its adjudication the presence of 
third parties of whom the court cannot acquire jurisdiction. But the 
pleader need not state the claim if (1) at the time the action was 
commenced the claim was the subject of another pending action, or (2) 
the opposing party brought suit upon the claim by attachment or other 
process by which the court did not acquire jurisdiction to render a 
personal judgment on that claim, and the pleader is not stating any 
counterclaim under this rule.
(b) Permissive Counterclaims. A pleading may state as a counterclaim 
any claim against an opposing party not arising out of the transaction 
or occurrence that is the subject matter of the opposing party's 
claim.
(c) Counterclaim Exceeding Opposing Claim. A counterclaim may or may 
not diminish or defeat the recovery sought by the opposing party. It may 
claim relief exceeding in amount or different in kind from that sought 
in the pleading of the opposing party.
(d) Counterclaim Maturing or Acquired After Pleading. A claim which 
either matured or was acquired by the pleader after serving a pleading 
may, with the permission of the court, be presented as a counterclaim by 
supplemental pleading.
(e) Omitted Counterclaim. When a pleader fails to set up a 
counterclaim through oversight, inadvertence, or excusable neglect, or 
when justice requires, the pleader may by leave of court set up the 
counterclaim by amendment."
This last option solves the potential malpractice problem; eliminates 
much if not all of the guesswork under A.B.C.G. as to which 
counterclaims must be brought; promotes judicial efficiency by ensuring 
that the parties litigate the claims they have against each other 
arising out of the same transaction or occurrence; and brings years of 
case law to bear on interpreting the statutes. Further, it would reduce 
the process to deciding one issue - whether the claim arises out of the 
same transaction or occurrence on which the plaintiff's suit was brought 
- by eliminating the troublesome task of deciding whether the claim 
would "nullify the initial judgment" or "(completely) impair rights in 
the initial action."
Conclusion
Although the statutes indicate exactly the opposite, certain 
counterclaims are mandated by case law. This not only presents a trap 
for the unwary but also continues to generate confusion, uncertainty, 
and litigation over whether a claim must be (or must have been) brought. 
A rule change would greatly assist circuit courts, litigants and their 
attorneys, and attorneys' insurers from taking a bath in the 
A.B.C.G. alphabet soup.
