delivered the Opinion of the Court.
Cleve Loney (Loney) appeals from an order of the Fourth Judicial District Court, Missoula County, dismissing his complaint for failure to state a claim upon which relief could be granted. We affirm.
The issue on appeal is whether the District Court erred in dismissing Loney’s complaint pursuant to Rule 12(b)(6), M.R.Civ.P., on the basis that his claim is barred by the doctrine of res judicata.
The law firm of Milodragovich, Dale and Dye, P.C. (the Firm) represented Loney in bankruptcy proceedings. In April of 1991, the Firm filed an action to recover unpaid attorney’s fees from Loney. Loney failed to answer the complaint and a default judgment in the amount of $7,626.42 was entered against him in September of 1991.
In October of 1994, Loney filed a complaint against the Firm requesting that the District Court declare the default judgment void and unenforceable because the debt had been discharged in bankruptcy. The Firm moved to dismiss the complaint pursuant to Rule 12(b)(6), M.R.Civ.P. After considering the parties’ pleadings and briefs, the District Court concluded that Loney’s failure to affirmatively plead discharge in bankruptcy pursuant to Rule 8(c), M.R.Civ.P, during the Firm’s action against him constituted a waiver of that defense. The court further concluded that Loney’s claim against the Firm was barred by the doctrine of res judicata and, on that basis, dismissed Loney’s complaint for failure to state a claim upon which relief could be granted. Loney appeals.
Did the District Court err in dismissing Loney’s complaint pursuant to Rule 12(b)(6), M.R.Civ.P., on the basis that his claim is barred by the doctrine of res judicata?
In evaluating a Rule 12(b)(6) motion to dismiss, courts are required to construe a complaint in the light most favorable to the plaintiff. A complaint should not be dismissed unless it appears that the plaintiff is not entitled to relief under any set of facts which could proved in support of the claim.
Boreen v. Christensen
(1994),
The doctrine of res judicata prevents a party from re-litigating a matter that the party has already had an opportunity to litigate.
Greenwood v. Steve Nelson Trucking, Inc.
(1995),
Loney does not dispute that three of the four res judicata criteria are satisfied in this case. The parties are the same in both actions; the Firm sued Loney in the earlier proceeding and Loney sued the Firm in the present action. The subject matter is also the same; both actions are based on the unpaid attorney’s fees the Firm is attempting to collect from Loney. The capacity of the parties involved has not changed in relation to the subject matter and the issues in the litigation.
Loney argues, however, that the issue in the present action is not the same as the issue resolved by the 1991 default judgment against him and, therefore, that his action against the Firm is not barred by the doctrine of res judicata. He contends that the issues are different in that the 1991 default judgment determined the amount of unpaid attorneys fees, while the issue in his action against the Firm is the voidness of that judgment based on the prior bankruptcy court order discharging his debts.
While it is true that the specific issue of whether the unpaid attorneys fees were discharged in bankruptcy was not litigated in the Firm’s action against Loney, the doctrine of res judicata bars not only issues which were previously litigated, but also issues which
could have been litigated
in the prior proceeding.
See State ex rel. Harlem Irrigation Dist. v. Montana Seventeenth Judicial Dist. Court
(1995), [
Moreover, Rule 8(c), M.R.Civ.P, required Loney to plead discharge in bankruptcy as an affirmative defense to the Firm’s complaint in the prior proceeding. We consistently have stated that failure to affirmatively plead a defense set forth in Rule 8(c) generally results in a waiver of that defense.
See, e.g., Brown v. Ehlert
(1992),
We conclude that the issue presented in this action is the same as the issue resolved by the 1991 default judgment against Loney. Having determined that all four criteria necessary for application of res judicata are satisfied, we hold that the District Court did not err in concluding that Loney’s claim against the Firm was barred by the doctrine of res judicata.
Loney also argues on appeal that, because the 1991 default judgment is void, he can collaterally attack that judgment at any time in a motion or an independent action pursuant to Rule 60(b)(4) and (6), M.R.Civ.P. Loney’s argument mischaracterizes Rule 60(b). Aparty seeking relief from a final order or judgment can file either a motion for relief based on one of the subsections of Rule 60(b) or an independent action under the residual clause of Rule 60(b).
See Brown v. Small
(1992),
Although Loney’s argument is purportedly based on Rule 60(b)(4) and (6), these subsections of Rule 60(b) are inapplicable here because he did not seek relief from the default judgment via a Rule 60(b) motion filed in that case.
See Brown,
The residual clause of Rule 60(b), M.R.Civ.P., allows a party to file an independent action for relief from a final judgment or order under very limited circumstances. We recently clarified that the available grounds for relief pursuant to the residual clause are: lack of personal notification, fraud upon the court, or an independent

action for extrinsic fraud.
In re Marriage of Miller
(1995), [
Loney argues that his independent action is premised on the Firm’s extrinsic fraud in failing to inform the District Court that the contested attorney’s fees had not been approved by the bankruptcy court. He relies on
In re Marriage of Madden
(1984),
Furthermore, we note that Loney’s specific extrinsic fraud argument, that the Firm failed to disclose to the District Court that the fees had not been approved by the bankruptcy court, is inseparable from the issue presented in the earlier proceeding of whether Loney owed the Firm attorney’s fees and, therefore, is inextricably intertwined with our conclusion that this issue is the same as that resolved by the 1991 default judgment against Loney. Under the circumstances of this case, Loney cannot circumvent the doctrine of res judicata through reliance on the residual clause of Rule 60(b), M.R.Civ.P.
Loney also argues, in his reply brief on appeal, that the court lacked jurisdiction to enter the 1991 default judgment. Rule 23(c), M.R.App.P., requires that an appellant’s reply brief be confined to new matter raised in the respondent’s brief; thus, an appellant is prohibited from raising new issues in a reply brief.
