Washington requires every public employee to subscribe to an oath that he is “not a subversive person or a member of the Communist Party or any subversive organization, foreign or otherwise, which engages in or advocates, abets, advises, or teaches the overthrow, destruction or alteration of the constitutional form of the government of the United States, or of the State of Washington, or of any political subdivision of either of them, by revolution, force or violence; . . Refusal so to do “on any *475grounds shall be cause for immediate termination of such employee’s employment.” *
Appellants brought this declaratory judgment action claiming the Act to be violative of due process as well as other provisions of the Federal Constitution. One of the claims is that no hearing is afforded at which the employee can explain or defend his refusal to take the oath. The Supreme Court of Washington did not pass on this point. The Attorney General suggests in his brief that prior to any decision thereon here, “the Supreme Court of Washington should be first given the opportunity to consider and pass upon” it. Moreover, appellants point to a recent case of the Washington Supreme Court, City of Seattle v. Ross, 54 Wash. 2d 655, 344 P. 2d 216 (1959), as analogous. There that court overturned an ordinance because it established a presumption of guilt without affording the accused an opportunity of a hearing to rebut the same. In the light of these circumstances we cannot say how the Supreme Court of Washington would construe this statute on the hearing point.
The declaratory nature of the case, the fact that the State’s statute here under attack supplements previous *476statutory provisions raising questions concerning the applicability of the latter, and the principle of comity that should be afforded the State with regard to the interpretation of its own laws, bring us to the conclusion that we must remand the case for further consideration. Cf. Williams v. Georgia, 349 U. S. 375 (1955).
Vacated and remanded.
Chapter 377, Laws of Washington 1955. The pertinent part of that statute reads:
“See. 1. Every person and every board, commission, council, department, court or other agency of the state of Washington or any political subdivision thereof, who or which appoints or employs or supervises in any manner the appointment or employment of public officials or employees . . . shall require every employee ... to state under oath whether or not he or she is a member of the communist party or other subversive organization, and refusal to answer on any grounds shall be cause for immediate termination of such employee's employment . . . .”
The Washington Supreme Court construed this statute as requiring the element of scienter.
