Mr. Justice Black
delivered the opinion of the Court.'
This case is here on appeal from the Supreme Court of Arizona under § 237 of the Judicial Code as amended, 28 U. S. C. § 344 (now 28 U. S. C. § 1257). It involves the constitutional validity of the following amendment to the Arizona Constitution, adopted at the 1946 general election:
“No person shall be denied the opportunity to obtain or retain employment because of non-membership in a labor organization, nor shall the state or any subdivision thereof, or any corporation, individual or association of any kind enter into any agreement, written or oral, which excludes any person from employment or continuation of employment because of non-membership in a labor organization.”
The Supreme Court of Arizona sustained the amendment as constitutional against the contentions that it “deprived union appellants of rights guaranteed under the First Amendment and protected against invasion by the State under the Fourteenth Amendment to the United States Constitution”; that it impaired the obligations of existing contracts in violation of Art. I, § 10, of the United States Constitution; and that it deprived appellants of due process of law, and denied them equal protection of the laws contrary to the Fourteenth Amendment. All of these questions, properly reserved in the state court, were decided against the appellants by the State Supreme Court. The same questions raised in the state court are presented here.
For reasons given in two other cases decided today we reject the appellants' contentions that the Arizona amendment denies them freedom of speech, assembly or petition, impairs the obligation of their contracts, or deprives them of due process of law. Lincoln Federal Labor Union v. Northwestern Iron & Metal Co. and Whitaker v. North Carolina, ante, p. 525. A difference between the Arizona amendment and the amendment and statute considered in the Nebraska and North Carolina cases has made it necessary for us to give separate consideration to the contention in this case that the Arizona amendment denies appellants equal protection of the laws.
The language of the Arizona amendment prohibits employment discrimination against non-union workers, but it does not prohibit discrimination against union workers. It is argued that a failure to provide the same protection for union workers as that provided for non-union workers places the union workers at a disadvantage, thus denying unions and their members the equal protection of Arizona's laws.
Although the Arizona amendment does not itself expressly prohibit discrimination against union workers, that state has not left unions and union members without protection from discrimination on account of union membership. Prior to passage of this constitutional amendment, Arizona made it a misdemeanor for any person to coerce a worker to make a contract “not to join, become or remain, a member of any labor organization” as a condition of getting or holding a job in Arizona. A section of the Arizona Code made every such contract (generally known as a “yellow dog contract”) void and unenforceable. Similarly, the Arizona constitutional amendment makes void and unenforceable contracts under which an employer agrees to discriminate against non-union workers. Statutes implementing the amendment have provided as sanctions for its enforcement relief by injunction and suits for damages for discrimination practiced in violation of the amendment. Whether the same kind of sanctions would be afforded a union worker against whom an employer discriminated is not made clear by the opinion of the State Supreme Court in this case. But assuming that Arizona courts would not afford a remedy by injunction or suit for damages, we are unable to find any indication that Arizona’s amendment and statutes are weighted on the side of non-union as against union workers. We are satisfied that Arizona has attempted both in the anti-yellow-dog-contract law and in the anti-discrimination constitutional amendment to strike at what were considered evils, to strike where those evils were most felt, and to strike in a manner that would effectively suppress the evils.
In Labor Board v. Jones & Laughlin Corp., 301 U. S. 1, this Court considered a challenge to the National Labor Relations Act on the ground that it applied restraints against employers but did not apply similar restraints against wrongful conduct by employees. We there pointed out, at p! 46, the general rule that “legislative authority, exerted within its proper field, need not embrace all the evils within its reach.” And concerning state laws we have said that the existence of evils against which the law should afford protection and the relative need of different groups for that protection “is a matter for the legislative judgment.” West Coast Hotel Co. v. Parrish, 300 U. S. 379, 400. We cannot say that the Arizona amendment has denied appellants equal protection of the laws.
Affirmed.

What follows is an opinion from the Supreme Court of the United States. Your task is to determine whether the decision of the court whose decision the Supreme Court reviewed was itself liberal or conservative. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. The lower court's decision direction is unspecifiable if the manner in which the Supreme Court took jurisdiction is original or certification; or if the direction of the Supreme Court's decision is unspecifiable and the main issue pertains to private law or interstate relations
