What follows is an opinion from the Supreme Court of the United States. Your task is to identify the petitioner of the case. The petitioner is the party who petitioned the Supreme Court to review the case. This party is variously known as the petitioner or the appellant. Characterize the petitioner as the Court's opinion identifies them.

Identify the petitioner by the label given to the party in the opinion or judgment of the Court except where the Reports title a party as the "United States" or as a named state. Textual identification of parties is typically provided prior to Part I of the Court's opinion. The official syllabus, the summary that appears on the title page of the case, may be consulted as well. In describing the parties, the Court employs terminology that places them in the context of the specific lawsuit in which they are involved. For example, "employer" rather than "business" in a suit by an employee; as a "minority," "female," or "minority female" employee rather than "employee" in a suit alleging discrimination by an employer.

Also note that the Court's characterization of the parties applies whether the petitioner is actually single entity or whether many other persons or legal entities have associated themselves with the lawsuit. That is, the presence of the phrase, et al., following the name of a party does not preclude the Court from characterizing that party as though it were a single entity. Thus, identify a single petitioner, regardless of how many legal entities were actually involved. If a state (or one of its subdivisions) is a party, note only that a state is a party, not the state's name.

Opinion:
DOUD et al., doing business as BONDIFIED SYSTEMS, et al. v. HODGE, AUDITOR OF PUBLIC ACCOUNTS OF ILLINOIS, et al.
No. 129.
Argued February 29, 1956.
Decided March 26, 1956.
John J. Yowell argued the cause and filed a brief for appellants.
William C. Wines, Assistant Attorney General of Illinois, argued the cause for appellees. With him on the brief was Latham Castle, Attorney General. Raymond S. Sarnow, Assistant Attorney General, was also on a Motion to Affirm.
Mr. Justice Minton
delivered the opinion of the Court.
The appellants are a partnership and its agent, all residents of Illinois. The partnership was engaged exclusively in the business of selling and issuing money orders in the State of Illinois. This business activity was to be conducted through agents who are principally persons engaged in operating retail drug, hardware and grocery stores. Appellant Derrick, a drug store proprietor, contracted with the partnership to act as its agent for the sale of money orders which it issued.
Illinois, by statute, has sought to license and regulate community currency exchanges. Section 1 of the Community Currency Exchanges Act defines a community currency exchange as “any person, firm, association, partnership or corporation, except banks incorporated under the laws of this State and National Banks organized pursuant to the laws of the United States, engaged ... in the business or service of, and providing facilities for, cashing checks, drafts, money orders or any other evidences of money acceptable to such community currency exchange, for a fee or service charge or other consideration, or engaged in the business of selling or issuing money orders under his or their or its name, or any other money orders (other than United States Post Office money orders, American Express Company money order, Postal Telegraph Company money orders, or Western Union Telegraph Company money orders), or engaged in both such businesses, or engaged in performing any one or more of the foregoing services.” Subsequent sections of the Act provide for the licensing and comprehensive regulation of such businesses.
Appellants brought this suit in the Northern District of Illinois seeking to enjoin the appellees, who are the Auditor of Public Accounts, the Attorney General of the State of Illinois and the State’s Attorney of Cook County, Illinois, from enforcing the Community Currency Exchanges Act against them. Jurisdiction was asserted under 28 U. S. C. § 1331. Appellants argued that a permanent injunction should be issued on the ground that the Act denied them equal protection of the laws in violation of § 1 of the Fourteenth Amendment to the Federal Constitution in that appellants are required to obtain a license and submit to regulation in the conduct of their money order business in the State while the American Express Company, which is engaged in the identical business activity in Illinois, is excepted from the operation of the Act. Since the complaint attacked the validity of a state statute under the Fourteenth Amendment to the Federal Constitution, the suit was tried before a three-judge District Court pursuant to 28 U. S. C. §§ 2281 and 2284.
The District Court heard the case at length and made findings of fact, the material portions of which we have set forth above. The District Court dismissed the complaint, holding that it lacked jurisdiction to determine the constitutional question presented in the absence of an authoritative determination by the Supreme Court of Illinois as to whether the exemption of the American Express Company from the terms of the Act is unconstitutional as applied to these appellants. 127 F. Supp. 853. We noted probable jurisdiction. 350 U. S. 814.
It is clear that the District Court had jurisdiction to entertain appellants’ complaint by virtue of the authority vested in it by 28 U. S. C. §§ 2281 and 2284. This Court has never held that a district court is without jurisdiction to entertain a prayer for an injunction restraining the enforcement of a state statute on grounds of alleged repugnancy to the Federal Constitution simply because the state courts had not yet rendered a clear or definitive decision as to the meaning or federal constitutionality of the statute.
We hold that the District Court has jurisdiction of this cause. It was error to dismiss the complaint for lack of jurisdiction. The judgment of the District Court is vacated and the case is remanded to it. We do not decide what procedures the District Court should follow on remand.
It is so ordered.
