The following excerpt is from Marsala v. Diaz, No. 2:19-cv-0513 KJM CKD P (E.D. Cal. 2020):
9. Any challenge to prisoner disciplinary proceedings which resulted in the revocation of good conduct sentence credit must be brought in a petition for writ of habeas corpus and not a 42 U.S.C. 1983 action unless the revoked sentence credit has been restored. See Edwards v. Balisok, 520 U.S. 641, 646-47 (1996).
10. Plaintiff cannot proceed on a 1983 claim for damages if the claim implies the invalidity of the length of his sentence. Heck v. Humphrey, 512 U.S. 477, 487 (1994).
