Background

S.D. and J.F., transgender women who were or had been incarcerated by the Oregon Department of Corrections, brought a putative class action alleging that state officials exposed them to a substantial risk of harm by housing them in men’s prisons. They sought relief on behalf of all current and future transgender women in ODOC custody.

The district court provisionally certified the class and entered a mandatory preliminary injunction requiring individualized housing reviews that began with a presumption of placement consistent with each inmate’s gender identity, absent a documented security justification. The injunction also required protective housing options, privacy measures, search restrictions, reporting mechanisms, and mental-health support. Oregon and corrections officials appealed, and the Ninth Circuit stayed the injunction and district-court proceedings pending appeal.

The Court’s Holding

The Ninth Circuit vacated the preliminary injunction, holding that the district court clearly erred in finding that ODOC used a default presumption favoring placement of transgender women in men’s prisons. The undisputed record described individualized, case-by-case reviews and showed that only 26 of 117 transgender women had requested placement in Oregon’s women’s prison. The appellate court concluded that the district court improperly inferred a categorical policy from the percentage of transgender women housed in men’s facilities and shifted the evidentiary burden away from the plaintiffs.

The court further held that the record did not establish that any presumed policy reflected deliberate indifference to a substantial risk of serious harm under the Eighth Amendment. It found the district court’s nationwide sexual-assault statistics stale and insufficiently tied to conditions in Oregon. The panel also held that the class lacked Rule 23 commonality because the record showed individualized placement decisions, differing alleged harms, and no department-wide policy of deliberate indifference. The remaining preliminary-injunction factors also favored defendants because individual allegations did not justify class-wide relief and the injunction substantially interfered with Oregon’s administration of its prisons.

The court remanded with instructions to decertify the class and directed that the mandate issue immediately. Its ruling eliminated the class-wide preliminary relief but did not finally adjudicate any individual plaintiff’s underlying constitutional claim.

Key Takeaways

  • A mandatory preliminary injunction requires the law and facts to clearly favor the plaintiffs, a more demanding showing than ordinary likelihood of success.
  • Placement statistics alone did not establish a categorical housing presumption where the record documented individualized reviews and most class members had not requested transfer to the women’s prison.
  • Individual allegations of harm could not support class certification or class-wide injunctive relief without evidence of a common policy or uniform deliberate indifference affecting the entire class.

Why It Matters

The decision emphasizes that courts must ground system-wide prison injunctions in current, institution-specific evidence and account for individualized security determinations. Statistical disparities may be relevant, but they cannot by themselves prove a uniform unconstitutional policy when significant variables remain unexplained.

The opinion also reinforces the close relationship between Rule 23 commonality and class-wide injunctive relief: absent proof of a common policy causing a shared constitutional injury, prisoners may have to pursue fact-specific claims individually rather than through a statewide class.
