dissenting.
The Court’s opinion appears to rest on three independent grounds:
(1) New York may, consistently with the Full Faith and Credit Clause, hold that a prior separate maintenance decree of one of its courts survives a decree of divorce within the scope of enforceability of the rule in Williams *550v. North Carolina, 317 U. S. 287, whether such divorce is granted in New York or by a sister State;
(2) By virtue of its interest in preventing its citizens from becoming public charges, New York may constitutionally provide that a domestic separate maintenance decree survives a sister-State divorce decree which must be respected in New York under the rule in the first Williams case, supra)
(3) A separate maintenance decree creates an obligation which may not, consistently with due process, be extinguished by a court lacking personal jurisdiction of the obligee, though possessed of jurisdiction to terminate her marital status, and any judgment purporting to do so is not entitled to extra-State recognition.
To the first of these grounds I assent, and if such is the law of New York I agree that the decision of the New York Court of Appeals in this -case must be upheld. It is for New York to decide whether its decrees for separate maintenance survive divorce or terminate with it, provided, of course, that its decision is not a mere attempt to defeat a federal right, given by the Full Faith and Credit Clause, under the guise of a determination of State law. Cf. Davis v. Wechsler, 263 U. S. 22, 24-25.
The second ground presents difficulties. I cannot agree that New York’s interest in its residents would justify New York in giving less effect to an enforceable Nevada divorce granted to one domiciled in Nevada, against a spouse not personally served, than it would give to a valid New York divorce similarly obtained. As to this, I agree with the views of my brother Jackson. If, on the other hand, New York does not so discriminate against enforceable “ex parte” divorce decrees granted by a sister State, no problem under the Full Faith and Credit Clause arises.
*551Furthermore, if the respondent had obtained her separate maintenance decree in Pennsylvania — which treats such decrees as terminated by any valid divorce, see Esenwein v. Esenwein, 325 U. S. 279 — and had subsequently moved to New York and there brought a suit based on the Pennsylvania decree, it is clear that New York’s interest in preventing the respondent from becoming a public charge would not justify refusal to treat the separate maintenance decree as having been terminated. New York would be required to refer to the law of Pennsylvania to determine whether the maintenance decree of that Commonwealth had survived the Nevada divorce, and, finding that it had not, the New York courts could not enforce it.
My difficulty with the third ground of the Court’s opinion is that Nevada did not purport, so far as the record discloses, to rule on the survival of the New York separate maintenance decree. Nevada merely established a change in status. It was for New York to determine the effect, with reference to its own law, of that change in status. If it was the law of New York that divorce put an end to its separate maintenance decree, the respondent’s decree would have been terminated not by the Nevada divorce but by the consequences, under the New York law, of a change in status, even though brought about by Nevada. Similarly, Nevada could not adjudicate rights in New York realty, but, if New York law provided for dower, a Nevada divorce might or might not terminate a dower interest in New York realty depending on whether or not New York treated dower rights as extinguished by divorce.
If the Nevada decree, insofar as it affected the New York separate maintenance decree, were violative of due process, New York of course would not have to give effect to it. It could not do so even if it wished. If the Nevada *552decree involved a violation of due process, there is an end of the matter and other complicated issues need not be considered! It would not matter whether New York had a special interest in preventing its residents from becoming public charges, or whether New York treated maintenance decrees as surviving a valid divorce.
Accordingly, the crucial issue, as I see it, is whether New York has held that no “ex parte” divorce decree could terminate a prior New York separate maintenance decree, or whether it has decided merely that no “ex parte” divorce decree of another State could. The opinion of the Court of Appeals leaves this crucial issue in doubt. The prior decisions of the New York courts do not dispel my doubts. Neither do the cases cited in the Court of Appeals’ opinion, which, with the exception of Wagster v. Wagster, 193 Ark. 902, do not involve “ex parte” domestic divorces. New York may legitimately decline to allow any “ex parte” divorce to dissolve its prior separate maintenance decree, but it may not, consistently with Williams v. North Carolina, 317 U. S. 287, discriminate against a Nevada decree granted to one there domiciled, and afford it less effect than it gives to a decree of its own with similar jurisdictional foundation. I cannot be sure which it has done.
I am reinforced in these views by Me. Justice Jackson’s dissent. As a New York lawyer and the Justice assigned to the Second Circuit, he is presumably not without knowledge of New York law. The Court’s opinion is written in a spirit of certitude that the New York law is contrary to that which Mr. Justice Jackson assumes it to be. Thus, on the issue that I deem decisive of the question whether New York has given full faith and credit to the Nevada decree — namely, whether under New York’s law divorce decrees based on publication terminate support — her law has thus far not spoken with ascertainable clarity. I would therefore remand the case to the New York Court of Appeals for clarification of its *553rationale. “. . . It is . . . important that ambiguous or obscure adjudications by state courts do not stand as barriers to a determination by this Court of the validity under the federal constitution of state action. Intelligent exercise of our appellate powers compels us to ask for the elimination of the obscurities and ambiguities from the opinions in such cases.” Minnesota v. National Tea Co., 309 U. S. 551, 557.
