MEMORANDUM *
Oregon Advocacy Center has standing to bring this claim. Oregon Advocacy Ctr. v. Mink, 322 F.3d 1101, 1113 (9th Cir.2003). The Superintendent has not carried his burden of proving collateral estoppel. Kamilche Co. v. United States, 53 F.3d 1059, 1062 (9th Cir.1995). OAC was not a party to the prior lawsuit, did not control the earlier litigation, and the legal assistance claim to disabled persons was not raised in the earlier suit. Nordhom v. Ladish Co., 9 F.3d 1402, 1405 (9th Cir.1993). Michael McCormack joined this action because Superintendent discontinued providing him access to federal appellate opinions.
McCormack’s claim is not moot because voluntary cessation does not moot a claim. Friends of the Earth v. Laidlaw, 528 U.S. 167, 189, 120 S.Ct. 693, 145 L.Ed.2d 610 (2000). The injury is also capable of repetition. Biodiversity Legal Found, v. Badgley, 309 F.3d 1166, 1173 (9th Cir.2002).
The district court did not err in finding a constitutional violation over access to the courts. Lewis v. Casey, 518 U.S. 343, 356, 116 S.Ct. 2174, 135 L.Ed.2d 606 (1996). The relief ordered is necessary to correct ongoing violations of the right of access to the courts.
Finally, attorney’s fees are properly awarded to OAC because plaintiffs pre*745vailed on the merits. Barrios v. Cal. Interscholastic Fed’n, 277 F.3d 1128, 1134 (9th Cir.2002).
AFFIRMED.
