                                   _________________

      THAPAR, Circuit Judge. Ordinarily, a plaintiff can’t have his case and settle it too.
Theodore McClain thinks otherwise. McClain settled his case—without reservation. Yet now
 No. 19-1726                              McClain v. Hanna                                 Page 2


he wants to represent a putative class action in the same case. Because McClain waived his right
to pursue these claims, we affirm.

       Less than a year ago, McClain sued Dalen Hanna and Hanna’s two law firms under the
Fair Debt Collection Practices Act and an analogous Michigan statute. See 15 U.S.C. § 1692 et
seq.; Mich. Comp. Laws § 445.251 et seq. McClain brought both individual and class claims.
Within a week, Hanna offered McClain a settlement under Federal Rule of Civil Procedure 68.
That settlement allowed judgment to be entered in McClain’s favor “as to all counts” of his
complaint. It also gave McClain his full damages (both actual and statutory) as well as his
litigation costs and reasonable attorney’s fees. Four days later, McClain accepted the settlement
offer but simultaneously filed a “placeholder” motion for class certification—apparently to
preempt a mootness ruling. Even so, the district court found the class claims to be moot and
entered a judgment dismissing both the individual and class claims.

       Yet McClain then pointed out that the court should have entered judgment in his favor
since that’s what the settlement said. So the district court entered an amended judgment “for
Plaintiff Theodore McClain as to all counts in Plaintiff’s complaint[.]” This appeal followed.

       According to McClain, the question here is whether his settlement mooted his class
claims. But there’s an initial problem with that question: the district court didn’t dismiss any of
McClain’s claims as moot. In the end, the court entered judgment in his favor “as to all counts.”
And it did so based on a settlement agreement in which McClain failed to reserve any right to
pursue his class claims on appeal. As a result, we need not reach the mootness question.

       For over a century, federal courts have followed a simple rule: parties may not challenge
a judgment to which they have consented. See, e.g., Nashville, C. & St. L. Ry. Co. v. United
States, 113 U.S. 261, 265 (1885).          Although people sometimes describe this rule as
“jurisdictional” or related to “standing,” in reality the consent waives any challenge on the
merits. See, e.g., Pac. R.R. v. Ketchum, 101 U.S. 289, 295 (1879); Shores v. Sklar, 885 F.2d 760,
764 n.7 (11th Cir. 1989) (en banc); 15A Wright & Miller, Federal Practice & Procedure § 3902,
at 91–93 (2d ed. 1992) (noting confusion between “standing” and “waiver” theories). Of course,
parties may preserve their right to challenge the judgment if they “reserve that right

unequivocally.” Innovation Ventures, LLC v. Custom Nutrition Labs., LLC, 912 F.3d 316, 329
(6th Cir. 2018) (citation omitted); see also 15A Wright & Miller, supra, § 3902, at 95 (noting
that “an express agreement reserving the right to appeal will be honored”). But if they fail to do
so, they may not challenge issues within the scope of the judgment.

          Our sister circuits have uniformly applied these principles to putative class actions. If a
named plaintiff settles his case and does not expressly reserve any right to pursue his class
claims, then he may not pursue those claims on appeal. See, e.g., Wright v. Calumet City,
848 F.3d 814, 817–21 (7th Cir. 2017); Potter v. Norwest Mortg., Inc., 329 F.3d 608, 613–15 (8th
Cir. 2003); Toms v. Allied Bond & Collection Agency, Inc., 179 F.3d 103, 105 (4th Cir. 1999);
Dugas v. Trans Union Corp., 99 F.3d 724, 726–29 (5th Cir. 1996); Walsh v. Ford Motor Co.,
945 F.2d 1188, 1190–92 (D.C. Cir. 1991) (R.B. Ginsburg, J.); Shores, 885 F.2d at 762–64;
Seidman v. City of Beverly Hills, 785 F.2d 1447, 1448 (9th Cir. 1986).

          As applied here, that rule leads to a straightforward result. In their settlement agreement,
the parties agreed to have judgment entered for “Plaintiff Theodore McClain as to all counts in
Plaintiff’s complaint[.]”     The settlement doesn’t except any claims or interests from the
judgment. Nor would it make much sense to read the settlement that way since the first three
“counts” of the complaint are “class claims.” So when McClain agreed to judgment on “all
counts,” that judgment unambiguously includes his class claims. Indeed, other courts have
reached the same conclusion based on similar language in settlement agreements. See Wright,
848 F.3d at 819 (“all claims”); Walsh, 945 F.2d at 1189 (“any and all . . . claims”). Thus,
McClain has waived any further interest in his class claims and may not pursue those claims on
appeal.

          We affirm.
