The district court had jurisdiction pursuant to 28 U.S.C. § 1343, and we have jurisdiction under 28 U.S.C. § 1291. We reverse the judgment of the district court and remand the action for further proceedings. The opinion of the three-judge panel, reported at 833 F.2d 804 (9th Cir.1987), is withdrawn.

The background of this appeal was succinctly stated in the panel opinion:
Phelps Dodge owns and operates a copper mine and milling plant in Ajo, a few miles south of Tucson. In 1983, the unions representing those employees went on strike. By all accounts the strike was bitter, dividing the town and resulting in violence by both strikers and non-strikers. Huge demonstrations and violent confrontations met the company’s attempt to replace the strikers. In this explosive situation both Pima County Sheriffs Department Officers, and Arizona Public Safety Officers were called to Ajo.
During the strike, several strikers were arrested and charged with felonies. Bail was set at $15,000 for each. When they could not post bail they were jailed in nearby Tucson. Other strikers were arrested or cited and charged with misdemeanors.
The Steelworkers sued Phelps Dodge, Pima County, the Sheriff and individual Deputies, the Arizona Department of Public Safety and individual officers, individual attorneys of the County Attorney’s Office, and the Ajo Justice of the Peace for conspiracy to deprive the strikers and their supporters of their constitutional rights in violation of 42 U.S.C. § 1983. They alleged discriminatory enforcement of the law, arrests without probable cause, and excessive bail.
The State Department of Public Safety and its officers, the Justice of the Peace, and the attorneys were dismissed. The district court then granted summary judgment and costs for Phelps Dodge. The Steelworkers appealed, contending that sufficient evidence of a conspiracy was presented to require a jury trial.
United Steelworkers of America v. Phelps Dodge Corp., 833 F.2d 804, 805 (9th Cir.1987).
We review the entry of summary judgment independently. Darring v. Kincheloe, 783 F.2d 874, 876 (9th Cir.1986). We are governed by the same standard used by the trial court under Fed.R.Civ.P. 56(c). Id. Under that standard, summary judgment is appropriate only if “the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” Fed.R.Civ.P. 56(e). Thus, the crucial question before us is whether the evidence presented by the Steelworkers, together with permissible inferences drawn from that evidence, is sufficient to establish a “genuine issue as to any material fact.”

The Steelworkers contend that a genuine issue exists as to whether Phelps Dodge was part of a conspiracy to deprive the strikers of their civil rights in violation of 42 U.S.C. § 1983. Actions may be brought pursuant to 42 U.S.C. § 1983 to redress constitutional violations under col- or of state law. Private parties act under color of state law if they willfully participate in joint action with state officials to deprive others of constitutional rights. Dennis v. Sparks, 449 U.S. 24, 27, 101 S.Ct. 183, 186, 66 L.Ed.2d 185 (1980); Adickes v. S.H. Kress & Co., 398 U.S. 144, 152, 90 S.Ct. 1598, 1605, 26 L.Ed.2d 142 (1970) (Adickes); United States v. Price, 383 U.S. 787, 794, 86 S.Ct. 1152, 1157, 16 L.Ed.2d 267 (1966); Fonda v. Gray, 707 F.2d 435, 437 (9th Cir.1983) {Fonda). Private parties involved in such a conspiracy may be liable under section 1983. Adickes, 398 U.S. at 152, 90 S.Ct. at 1605.
To prove a conspiracy between the state and private parties under section 1983, the Steelworkers must show “an agreement or ‘meeting of the minds’ to
