NOT FOR PUBLICATION
Cunio appeals the district court's dismissal of his 42 U.S.C. § 1983 claim on Younger abstention grounds. We review de novo whether Younger abstention applies. Green v. City of Tucson, 255 F.3d 1086, 1093 (9th Cir. 2001) (en banc).
Younger abstention is only appropriate if "the federal plaintiff is not barred from litigating federal constitutional issues in the state proceeding." San Jose Silicon Valley Chamber of Commerce Political Action Comm. v. City of San Jose, 546 F.3d 1087, 1092 (9th Cir. 2008). The pending proceeding before the Oregon Court of Appeals does not provide Cunio "an adequate opportunity to raise his federal constitutional claims." Meredith v. Oregon, 321 F.3d 807, 818 (9th Cir. 2003). That proceeding only addresses the 48-year minimum sentence imposed by the Oregon Board of Parole and Post-Prison Supervision ("Parole Board") in 2012 for Cunio's homicide offenses. See Or. Rev. Stat. § 144.335 (challenging final orders of the Parole Board). Oregon law required Cunio to challenge the 23-year portion of his determinate guidelines sentence for his non-homicide offenses in separate proceedings. See Or. Rev. Stat. §§ 138.050 (direct appeal), 138.510-680 (post-conviction relief). None of these proceedings provided Cunio an "adequate" and "full and fair" opportunity to challenge the combined effect of his sentences as a de facto life sentence without parole, or to challenge the constitutionality of Oregon's bifurcated sentencing scheme for juveniles convicted of homicide and non-homicide crimes in a single judgment. Meredith, 321 F.3d at 818-19. The district court therefore should not have abstained.
