Metropolitan Life was not put to its proof. Herbert did not satisfy the insurer’s discovery requests, and the district judge entered a default judgment. 1989 WL 153558, 1989 U.S. Dist. LEXIS 13384 (N.D.Ill.), rehearing denied, 1990 WL 44687, 1990 U.S. Dist. LEXIS 3852. His estate (Herbert died in April 1990) contends that the judge should have used some lesser sanction. Several jurisdictional hurdles lie between us and that question.
Appellate jurisdiction is the first. On November 7, 1989, the district judge entered an order stating that “plaintiffs motion for default judgment is granted.” This was not appealable; it is one thing to grant a motion and another to enter a judgment. Metropolitan Life wanted a declaratory judgment, which the district court had yet to provide. Nonetheless, Cammon (as we call Herbert and his estate, without distinguishing the two) filed a notice of appeal. We dismissed this and gave two reasons: first, the absence of relief made the document non-final, see Cleaver v. Elias, 852 F.2d 266 (7th Cir.1988); Foremost Sales Promotions, Inc. v. Director, BATF, 812 F.2d 1044 (7th Cir.1987); second, Cam-mon’s pending motion for reconsideration under Fed.R.Civ.P. 59 prevented appeal. The district court denied the motion and on April 6, 1990, entered an order on the form used for Rule 58 judgments. This order provides in full:
IT IS ORDERED AND ADJUDGED pursuant to the Memorandum Opinion dated November 7, 1989, default judgment is entered in favor of the plaintiff, METROPOLITAN LIFE INSURANCE COMPANY and against defendant HERBERT CAMMON. Final judgment is hereby entered accordingly.
This document, like the order of November 7, neglected to supply the declaratory relief Metropolitan Life requested — for that matter, to provide any relief. It was accordingly not an appealable judgment. Nonetheless, Cammon filed a second notice of appeal. Metropolitan Life took the proper step of asking the district judge to award some relief. On May 7 the court amended its order by adding a declaratory judgment that Metropolitan Life has no liability under the policy but must refund the premium.
Cammon contends that the May 7 judgment is invalid because his appeal from the April 6 judgment transferred jurisdiction to this court. He could not be more wrong. It is the appeal from that April 6 “judgment” that is ineffectual. We had already held that no appeal would lie until the judge entered declaratory relief. Why Cammon filed a notice of appeal from the document entered on April 6 is a mystery to us. It is also mysterious why the district judge omitted any relief. Cammon’s premature notice of appeal did not prevent the judge from correcting his oversight and entering final judgment.
Having filed two appeals from non-final documents, Cammon neglected to file a notice of appeal from the final judgment. It is tempting to apply the three-knockdown rule and stop the contest. Cammon is saved, however — not by the bell, but by Fed.R.App.P. 4(a)(2), which treats a premature notice of appeal as if it had been filed after the entry of judgment. This rule “permits a notice of appeal from a nonfinal decision to operate as a notice of appeal from the final judgment ... when a district court announces a decision that would be appealable if immediately followed by the entry of judgment.” FirsTier Mortgage Co. v. Investors Mortgage Insurance Co., — U.S. —, 111 S.Ct. 648, 653, 112 L.Ed.2d 743 (1991) (emphasis in original). The district court’s opinions announce a decision that was appealable as soon as the proper judgment was entered. Cammon’s notice of appeal accordingly sprang into force when the final judgment was entered on May 7.
Before the entry of default, Cammon filed a motion arguing that the court lacks subject-matter jurisdiction. The judge brushed aside this motion, refusing to entertain argument, and then, when entering the default, called the question “moot”. It was and is not moot. No court may enter judgment on the merits — which a default judgment is — if it lacks jurisdiction. A federal court must examine its own jurisdic
