Mr. Justice Frankfurter
delivered the opinion of the Court.
In No. 49, twenty-five classified civil servants of the County of Los Angeles brought an action in the Superior Court of that County, and in No. 50, suit was brought by one such employee. The respective plaintiffs sought relief against enforcement by the County and its officials of what is colloquially known as a loyalty test, and they did so for themselves and “in a representative capacity ... on behalf of 20,000 employees of Los Angeles County similarly situated.”
The plaintiffs, petitioners here, alleged that on August 26, 1947, the Board of Supervisors of the County of Los Angeles adopted as part of its “Loyalty Check” program the requirement that all County employees execute a prescribed affidavit. It consisted of four parts, fully set forth in the Appendix. By Part A, each employee is required to support the Constitution of the United States, and the Constitution and laws of the State of California; by Part B, he forswears that since December 7, 1941, he has been a member of any organization advocating the forcible overthrow of the Government of the United States or of the State of California or of the County of Los Angeles, that he now advocates such overthrow, or that he will in the future so advocate directly or through an organization; by Part C, he is required to list his aliases; and by Part D, he is asked to indicate whether he has ever been “a member of, or directly or indirectly supported or followed” any of an enumerated list of 145 organizations. Asserting fear of penalizing consequences from the loyalty program, and claiming that the law of California and the Constitution of the United States barred coercive measures by the County to secure obedience to the alleged affidavit requirement, petitioners brought these actions. Demurrers to the complaints were sustained by the Superior Court and its judgments were affirmed by the District Court of Appeal for the Second Appellate District. 88 Cal. App. 2d 481, 199 P. 2d 429. After the Supreme Court of California denied discretionary review we brought the case here because, on the showing then before us, serious questions seemed raised as to the scope of a State’s power to safeguard its security with due regard for the liberty guaranteed by the Due Process Clause of the Fourteenth Amendment. 337 U. S. 929. In view, however, of the circumstances that became manifest after the cases came to argument, we are precluded from reaching these constitutional issues on their merits.
To begin with, the California decision under review does not tell us unambiguously what compulsion, if any, the loyalty order of August 26, 1947, carried. It is unequivocally clear that the lower court refused to decide whether an employee who discloses his so-called “subversive” activities or connections may for that reason be discharged. It is not clear, however, whether, as petitioners contend, the lower court meant to hold that the Board of Supervisors may discharge an employee who refuses to file an affidavit. This ambiguity renders so doubtful whether an issue under the United States Constitution is before us that at most we would exercise jurisdiction to obtain clarification by the State court. See Honeyman v. Hanan, 300 U. S. 14; Minnesota v. National Tea Co., 309 U. S. 551; State Tax Comm’n v. Van Cott, 306 U. S. 511; Herb v. Pitcairn, 324 U. S. 117. But the circumstances which were called to our attention after the cases reached us leave no doubt that the issues which led us to bring them here are not ripe for constitutional adjudication. American Wood Paper Co. v. Heft, 8 Wall. 333, 131 U. S. xcii; Commercial Cable Co. v. Burleson, 250 U. S. 360.
As of July 20, 1948, nearly a year after the original loyalty order, all but 104 of the 22,000 officers and employees of the County had executed the prescribed affidavit. On that day, these noncomplying employees were advised that the Board of Supervisors had adopted an order providing (1) that unless they had executed Parts A, B and C of the affidavit by July 26 they would be discharged, and (2) that unless they had executed Part D by that time they would be discharged “if and when the loyalty test litigation now pending is finally concluded with a determination that the County was justified in requiring from its employees the information embodied in Paragraph 'D.’ ”
This order was the first explicit announcement of sanctions by the Board in furtherance of its loyalty program. By July 26 the entire affidavit had been executed by all but 45 employees. Of these, 29 had executed only Parts A, B and C. Sixteen stood their ground against any compliance. They invoked their administrative remedy of review before the Civil Service Commission which decided against them. On June 24 of this year these sixteen discharged employees sought a writ of mandate from the Superior Court of the County of Los Angeles to review the decision of the Civil Service Commission, with a prayer for reinstatement and back pay. We are advised that this litigation is now pending in the Superior Court. The petitioners here, except one in No. 49, signed Parts A, B and C, and that petitioner is a party in the case before the Superior Court.
From this it appears that the California courts have before them for the first time since the inception of the loyalty program an order which expressly threatens sanctions. These sanctions are being challenged under State law as well as under the United States Constitution. For all we know the California courts may sustain these claims under local law. The present cases are here from an intermediate State appellate court because the State Supreme Court did not deem the records before it to present issues deserving of its discretionary review. The explicit sanctions of the modified order may lead the Supreme Court of California to pass on them should the litigation now pending in the lower courts go against the contentions of these petitioners. It is relevant to note that when claims not unrelated to those now urged before us, but based on State law, have come before the Supreme Court of California that tribunal has not been insensitive to them. See Communist Party v. Peek, 20 Cal. 2d 536, 127 P. 2d 889; James v. Marinship Corp., 25 Cal. 2d 721, 155 P. 2d 329. If their claims are recognized by the California courts, petitioners would of course have no basis for asserting denial of a Federal right. It will be time enough for the petitioners to urge denial of a Federal right after the State courts have definitively denied their claims under State law.
Due regard for our Federal system requires that this Court stay its hand until the opportunities afforded by State courts have exhausted claims of litigants under State law. This is not what is invidiously called a technical rule. The best teaching of this Court’s experience admonishes us not to entertain constitutional questions in advance of the strictest necessity. Decent respect for California and its courts demands that this Court wait until the State courts have spoken with knowledge of the events brought to light for the first time at the bar of this Court. Since the writs must be dismissed because constitutional questions which brought these cases here are not ripe for decision, all subsidiary questions fall. See Rescue Army v. Municipal Court, 331 U. S. 549, 585; Alabama State Fed. of Labor v. McAdory, 325 U. S. 450; C. I. O. v. McAdory, 325 U. S. 472.
Dismissed.
Mr. Justice Douglas took no part in the consideration or disposition of these cases.

Clearly enough some discharges or demotions of classified employees by the Board of Supervisors are not final. The division of authority between the Board and the County Civil Service Commission is thus formulated by the lower court:
“In case the appointing power wishes to discharge a civil service employee the reasons therefor must be given and, thereupon, if the employee so desires he is entitled to a hearing before the commission. If the commission finds that the reasons are not sufficient, the discharge is void despite anything the appointing power can do about it.
“From what has so far been said, it is self-evident that neither the board nor its agents can discharge a civil service employee for any cause that the civil service commission finds insufficient. Accordingly, if in the view of the board of supervisors, or its agents as the appointing power, a civil service employee should be discharged on the sole ground that the employee is 'subversive,’ the discharge or attempt to discharge on that ground is of no effect if, on hearing, the commission holds otherwise.
. . . . .
Whether the appointing power will or will not discharge employees as claimed by the plaintiffs, for causes of the character enumerated, and whether the civil service Commission will uphold such discharges, if any, on such causes, are not matters upon which this Court may speculate or adjudicate at this time. . . .” 88 Cal. App. 2d 481, 493, 497, 199 P. 2d 429, 436, 438-39. See Los Angeles County Charter, Art. IX, § 34 (13) in Cal. Laws 1913, p. 1495, as amended, Cal. Stat. 1939, p. 3147.
The affidavit in the order of July 20, 1948, differed from the affidavit in the original order only in that Part B was elucidated to an extent not here relevant and a few organizations listed in Part D were omitted.
Article IX, § 41 of the Los Angeles Charter provides: “No person in the classified service, or seeking admission thereto, shall be appointed, reduced or removed or in any way favored or discriminated against because of his political or religious opinions or affiliations.” Cal. Laws 1913, p. 1496. Article I, §§ 1, 4, 9, 10, 16, 21 of the California Constitution contains safeguards against infringement of the rights at which petitioners claim the loyalty investigation strikes.
