Mr. Justice Blackmun
delivered the opinion of the Court.
On the merits, this case raises the same question as to the constitutionality of §§ 202 (d)(3) and 216 (h)(3) (C)(ii) of the Social Security Act, 64 Stat. 484, as amended, and 79 Stat. 410, 42 U. S. C. §§ 402 (d) (3) and 416 (h) (3) (C) (ii), as was presented in Mathews v. Lucas, ante, p. 495. The present litigation, however, also raises certain jurisdictional issues. It now has become apparent that the simultaneous submission of Lucas to the Court, and our decision in that case today, make it unnecessary for us specifically to decide the jurisdictional questions.
I
Appellant Gregory Norton, Jr., was born out of wedlock in February 1964. Both his father and his mother then were high school students, aged, respectively, 16 and 14, who lived separately at home with their parents. [526]*526The two never married and, indeed, never lived together. Appellant always has resided with his maternal grandmother and has been cared for by her. When Gregory was born, his father contributed six dollars and some clothing and other habiliments for the baby, but, being so young and unemployed, he never assumed appellant’s actual support.
In February 1965 the father entered military service. He was killed in Vietnam on May 19, 1966, at age 19. Before his death, the father apparently took some initial steps (the procurement of a birth certificate and other items) necessary for the processing of a dependent child’s military allotment. The father failed, however, to complete the required procedures before he was killed.
In September 1969 appellant’s maternal grandmother filed on his behalf an application for a surviving child’s benefits under § 202 (d)(1) of the Act, 42 U. S. C. § 402 (d)(1), based on the father’s earnings record. An administrative hearing followed. The Hearing Examiner concluded that appellant was not entitled to benefits as a dependent child because his father, at the time of his death, was neither living with appellant nor contributing to appellant’s support.1 App. 13-19. The subse[527]*527quent administrative appeal was no more successful. Id., at 20-21.
The present action was then instituted on behalf of appellant against the Secretary of Health, Education, and Welfare. By the complaint, relief was sought alternatively on statutory and constitutional grounds. First, it was asserted that, by his attempt to secure a military allotment for appellant, the father, at the time of his death, in fact was contributing to appellant's support, within the meaning of § 216 (h) (3) (C) (ii) of the Act, and that appellant therefore was a dependent of the father, under §§ 202 (d)(1) and (3) (1970 ed. and Supp. IV), and entitled to benefits. Second, it was asserted that, by creating a presumption of dependency, and consequent qualification for benefits, for legitimate children generally, and for illegitimate children under certain, circumstances, see n. 1, but denying the presumption to appellant and others similarly situated, the Act discriminated against appellant's class, in violation of the guarantee of equal protection implicit in the Due Process Clause of the Fifth Amendment.
Appellant’s statutory claim was initially considered and rejected by a single District Judge. Norton v. Richardson, 352 F. Supp. 596 (Md. 1972). In view of the complaint's request for certification of a class pursuant to Fed. Rule Civ. Proc. 23 (c)(1), and for classwide injunc-tive relief against the alleged unconstitutional operation of the Act's presumptions of dependency, a three-judge court was convened under 28 U. S. C. §§ 2282 and 2284 (1970 ed. and Supp. IV) to pass upon the constitutional [528]*528claim. The three-judge court first agreed with, and reaffirmed, the single judge’s rejection of appellant’s statutory claim. Norton v. Weinberger, 364 F. Supp. 1117, 1120 (1973). The court went on to identify the plaintiff class, id., at 1120-1121,2 but on the merits of the constitutional claim it ruled in favor of the Secretary and granted summary judgment in his favor. Id., at 1121— 1131.
Appellant, taking the position that the three-judge court had denied his request for an order enjoining enforcement of provisions of the Act, lodged a direct appeal here pursuant to 28 U. S. C. § 1253. While his jurisdictional statement was pending, Jimenez v. Weinberger, 417 U. S. 628 (1974), was decided. This Court thereafter vacated the three-judge court’s judgment and remanded the case for further consideration in the light of Jimenez. Norton v. Weinberger, 418 U. S. 902 (1974).
On the remand, the same three-judge court, with one judge now dissenting, adhered to its earlier conclusion in favor of constitutionality. Norton v. Weinberger, 390 F. Supp. 1084 (1975). Appellant has again appealed. We postponed the question of jurisdiction to the hearing of the case on the merits, 422 U. S. 1054 (1975), and, in doing so, cited Weinberger v. Salfi, 422 U. S. 749, 763 n. 8 (1975), which just then had been decided. Subsequently, we set the case for oral argument with Mathews v. Lucas, ante, p. 495. 423 U. S. 819 (1975).
II
The question whether the three-judge court was properly convened upon appellant’s demand for injunctive re[529]*529lief is relevant, of course, to our appellate jurisdiction. If the court was not empowered to enjoin the operation of a federal statute, then three judges were not required to hear the case under 28 U. S. C. § 2282, and this Court has no jurisdiction under 28 U. S. C. § 1253.3 Accordingly, appellant and the Secretary have debated whether the District Court possessed injunctive power under § 205 (g) of the Act,4 42 U. S. C. §405 (g), and whether, in the light of § 205 (h),5 42 U. S. C. § 405 (h), relief was available under the mandamus statute, 28 U. S. C. [530]*530§ 1361,6 or under the Administrative Procedure Act, 5 II. S. C. § 701 et seg.7
We think it unnecessary, however, to resolve the details of these difficult and perhaps close jurisdictional arguments. The substantive questions raised on this appeal now have been determined in Mathews v. Lucas, ante, p.

The question whether the three-judge court was properly convened upon appellant’s demand for injunctive re[529]*529lief is relevant, of course, to our appellate jurisdiction. If the court was not empowered to enjoin the operation of a federal statute, then three judges were not required to hear the case under 28 U. S. C. § 2282, and this Court has no jurisdiction under 28 U. S. C. § 1253.3 Accordingly, appellant and the Secretary have debated whether the District Court possessed injunctive power under § 205 (g) of the Act,4 42 U. S. C. §405 (g), and whether, in the light of § 205 (h),5 42 U. S. C. § 405 (h), relief was available under the mandamus statute, 28 U. S. C. [530]*530§ 1361,6 or under the Administrative Procedure Act, 5 II. S. C. § 701 et seg.7
We think it unnecessary, however, to resolve the details of these difficult and perhaps close jurisdictional arguments. The substantive questions raised on this appeal now have been determined in Mathews v. Lucas, ante, p. 495.8 This disposition renders the merits in the [531]*531present case a decided issue and thus one no longer substantial in the jurisdictional sense.
Assuming that the three-judge court was correctly convened, and that we have jurisdiction over the appeal, the appropriate disposition, in the light of Mathews v. Lucas, plainly would be to affirm the judgment entered in this case in favor of the Secretary. Assuming, on the other hand, that we lack jurisdiction because the three-judge court was needlessly convened, the appropriate disposition would be to dismiss the appeal. When an appeal to this Court is sought from an erroneously convened three-judge district court, we retain the power “ ‘to make such corrective order as may be appropriate to the enforcement of the limitations’ ” which 28 U. S. C. § 1253 imposes. Bailey v. Patterson, 369 U. S. 31, 34 (1962), quoting Gully v. Interstate Natural Gas Co., 292 U. S. 16, 18 (1934). What we have done recently, and in most such cases where the jurisdictional issue was previously unsettled — and we do not imply that our doing so is statutorily or otherwise compelled — has been to vacate the district court judgment and remand the case for the entry of a fresh decree from which an appeal may be taken to the appropriate court of appeals. Gonzalez v. Employees Credit Union, 419 U. S. 90, 101 (1974), is an example. In the present case, however, the decision in Lucas has rendered the constitutional issues insubstantial and so much so as not even to support the jurisdiction of a three-judge district court to consider their merits on remand. See, e. g., Hicks v. Miranda, 422 U. S. 332, 343-345 (1975); Hagans v. Lavine, 415 U. S. 528, 536-538 (1974). Thus, there is no point in remanding to enable the merits to be considered by a court of [532]*532appeals. See McLucas v. DeChamplain, 421 U. S. 21 (1975).9
It thus is evident that, whichever disposition we undertake, the effect is the same. It follows that there is no need to decide the theoretical question of jurisdiction in this case. In the past, we similarly have reserved difficult questions of our jurisdiction when the case alternatively could be resolved on the merits in favor of the same party. See Secretary of the Navy v. Avrech, 418 U. S. 676 (1974). The Court has done this even when the original reason for granting certiorari was to resolve the jurisdictional issue. See United States v. Augenblick, 393 U. S. 348, 349-352 (1969). Although such a disposition would not be desirable under all circumstances, we perceive no reason why we may not so proceed in this case where the merits have been rendered plainly insubstantial. Cf. McLucas v. DeChamplain, 421 U. S., at 32. Making the assumption, then, without deciding, that our jurisdiction in this cause is established, we affirm the judgment in favor of the Secretary [533]*533on the basis of our decision in Mathews v. Lucas, ante, p. 495.
It is so ordered.
