Background

Warren Andrew Nelsen, a California state prisoner proceeding pro se, filed a petition for a writ of habeas corpus under 28 U.S.C. § 2254 in the Eastern District of California. The petition was screened under Rule 4 of the Rules Governing Section 2254 Cases, which permits dismissal before a response is ordered if it plainly appears the petitioner is not entitled to relief. The magistrate judge identified that Nelsen's petition raised issues concerning Case No. 2:26-cv-01524-AC, a prior § 1983 action he filed in the Sacramento Division regarding a data breach that occurred while he was confined at Mule Creek State Prison.

The court noted that federal habeas jurisdiction under § 2254(a) extends only to persons in custody pursuant to a state-court judgment and only on the ground that the custody violates the Constitution, laws, or treaties of the United States. Citing Ninth Circuit authority, the court emphasized that the statute requires the applicant to be contending that he is 'in custody' in violation of federal law. The magistrate judge concluded that whether Nelsen was entitled to relief in his previous § 1983 action does not establish that he is in custody in violation of the Constitution or other federal laws.

The Court’s Holding

The magistrate judge recommended that the petition for writ of habeas corpus be dismissed for failure to state a cognizable federal habeas claim. The court found that Nelsen's challenge to the outcome of his § 1983 data-breach lawsuit does not satisfy the 'in custody' requirement of § 2254 because it does not allege that his current confinement violates federal law. The clerk of court was directed to randomly assign the action to a district judge for further proceedings.

The findings and recommendation were submitted pursuant to 28 U.S.C. § 636(b)(1)(B) and Local Rule 304, with notice that Nelsen has 30 days to file written objections limited to 15 pages, and that failure to object may waive the right to appeal the district court's order. The magistrate judge also noted that to the extent Nelsen challenges the outcome of his § 1983 case, he may file an appropriate motion in that action rather than seeking habeas relief.

Key Takeaways

  • A § 2254 habeas petition must challenge the legality of the petitioner's custody, not the outcome of a separate civil rights lawsuit.
  • Challenging a prior § 1983 judgment regarding a prison data breach does not satisfy the 'in custody in violation of the Constitution' requirement of 28 U.S.C. § 2254(a).
  • Rule 4 screening permits early dismissal of habeas petitions that plainly fail to state a cognizable claim, before the respondent is required to answer.
  • The magistrate judge's findings and recommendation are subject to de novo review by a district judge upon timely objection, and failure to object within 30 days may waive appellate rights.
  • The petitioner was advised that any challenge to the § 1983 case outcome should be pursued in that action, not through habeas corpus.

Why It Matters

This decision reinforces the fundamental jurisdictional boundary between habeas corpus and civil rights actions: habeas attacks the fact or duration of custody, while § 1983 addresses conditions of confinement or other constitutional violations that do not necessarily imply unlawful custody. The ruling illustrates the gatekeeping function of Rule 4 screening in filtering out petitions that misconstrue the scope of habeas relief, preserving judicial resources and clarifying the proper procedural vehicle for prisoners' grievances.

The recommendation also highlights the practical consequences of the magistrate judge's screening authority under 28 U.S.C. § 636(b)(1)(B). By recommending dismissal before the respondent is ordered to respond, the court avoids unnecessary litigation over a claim that cannot succeed under the habeas statute. The 30-day objection period and the warning about waiver of appellate rights underscore the importance of timely participation in the review process.
