¶5Appellant, who was disbarred in 1957 for engaging in a homosexúal act on a public beach, State v. Kimball, 96 So.2d 825 (Fla.1957),1 challenges the lower court’s stay based on abstention in his suit under 42 U.S.C. § 1983 (1970), against the State Bar of Florida. Below he attacked the constitutionality2 of his disbarment and of rule 11.02(3) of article XI of the integration rule of the Florida Bar, which provides that an attorney may be disciplined for any act contrary to “good morals.” In the court below, appellant sought declarations that his disbarment was unconstitutional and that rule 11.02(3) is unconstitutional, as well as an injunction preventing the Bar from engaging in future harassment and interference with his constitutional rights. Finding that the lower court’s abstention was improper, we vacate the stay and remand.
¶6The lower court abstained by invoking the unclear-state-law branch of the abstention doctrine, cf. Harman v. Forssenius, 380 U.S. 528, 85 S.Ct. 1177, 14 L.Ed.2d 50 (1965), on the ground that Florida courts had not recently construed rule 11.02(3) as it applied to homosexuals. The general rule is that a court should abstain only if state law is fairly subject to an interpretation that will render unnecessary or substantially modify the federal question. Kusper v. Pontikes, 414 U.S. 51, 54-55, 94 S.Ct. 303, 38 L.Ed.2d 260 (1973); Harman v. Forssenius, 380 U.S. 528, 535, 85 S.Ct. 1177, 14 L.Ed.2d 50 (1965). But in 1957, the Florida Su preme Court spoke clearly, and decisively on the issue raised here by disbarring appellant, and recent cases only reinforce the view that under Florida law an attorney can be disbarred for immoral conduct unrelated to the practice of law. See Florida Bar v. Kay, 232 So.2d 378 (Fla.1970) (disbarment based on defendant’s conviction for indecent exposure in a public lavatory, which violated a city ordinance; unclear if decision is based on rule 11.02(3)(a) or (3)(b)); Florida Bar v. Hefty, 213 So.2d 422 (Fla.1968) (disbarment based on defendant’s sexual misconduct with his ten-year-old stepdaughter). Thus, the abstention was improper.
¶7One question not raised on appeal is whether either the Florida Supreme Court or its members are “indispensable parties” under Rule 19(b), Fed.R.Civ:P.,3 and must be joined or the action dismissed.4*1307A party does not waive the defense of failure to join an indispensable party by neglecting to raise it; an objection can be raised at any time even by a reviewing court on its own motion, see Provident Tradesmens Bank & Trust Co. v. Patterson, 390 U.S. 102, 109-12, 88 S.Ct. 733, 19 L.Ed.2d 936 (1968); Boles v. Greeneville Housing Authority, 468 F.2d 476, 479 (6th Cir. 1972) (Tuttle, J.); Haby v. Standard Oil & Gas Co., 225 F.2d 723, 724 (5th Cir. 1955); 7 C. Wright & A. Miller, Federal Practice & Procedure: Civil § 1609, at 88-94 (1972). In the absence of an indispensable party, the federal courts are no more empowered to render a declaratory judgment than we would be to give affirmative relief. We could not resolve this issue without additional briefs examining each of the factors enumerated in Rule 19, and we would have to remand in any case if we held for appellee on this issue. Therefore, we think it appropriate to remand in the first instance so that before reaching the other issues5 raised the district court can determine whether the supreme court or its members can or should have been joined under the provisions of Rule. 19.
