Surie Alexander v. Dau Nguyen, 78 F.4th 1140

Background

Surie Alexander, a pretrial detainee with aphasia, was admitted to Patton State Hospital and assigned to Unit 72 under psychiatrist Dr. Dau Nguyen.
On April 29, 2017, a fellow patient struck Alexander; staff investigated, counseled both patients, adjusted the aggressor’s medication and dining access, and Dr. Nguyen (after consulting staff) decided not to transfer Alexander, partly because Alexander said he felt safe and did not want to move.
On May 10, 2017, the same patient struck Alexander again; injuries were minor (superficial scratch and swelling), and staff initially used restraints and one-on-one supervision but concluded those were not long-term solutions.
After the second attack, Unit 72 staff, Dr. Nguyen, and Alexander’s wife agreed to transfer Alexander to Unit 71 on May 17, 2017; no further assaults occurred and Alexander was later released as competent.
Alexander sued Dr. Nguyen under 42 U.S.C. § 1983 claiming a Fourteenth Amendment substantive due process violation for failing to protect him after the first attack; the district court granted summary judgment to Dr. Nguyen on qualified immunity grounds.
The Ninth Circuit affirmed, deciding on the merits that Dr. Nguyen’s post-incident decisions were reasonable under the applicable standards and thus did not violate Alexander’s constitutional rights.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Proper constitutional standard for pretrial detainee violence/medical claims	Gordon/Kingsley objective deliberate-indifference standard applies to evaluate adequacy of care and protective measures	Youngberg professional-judgment standard also relevant; both focus on reasonableness	Court treated both standards as overlapping and evaluated reasonableness; either standard would require more than negligence
Whether Dr. Nguyen’s decisions after the April 29 assault violated the Fourteenth Amendment	Nguyen was deliberately indifferent/unreasonable for keeping Alexander in Unit 72, leading to a second assault	Dr. Nguyen investigated, consulted staff, weighed relevant factors (severity, prior incidents, victim preference, treatment impact), and implemented mitigating measures	No constitutional violation; Dr. Nguyen acted reasonably and did not exhibit the requisite reckless or conscious indifference
Liability based on subsequent assault (strict liability argument)	Second assault shows original decision was unreasonable; plaintiff effectively seeks strict liability for subsequent incidents	Hindsight cannot convert reasonable professional judgment into constitutional violation; law does not impose strict liability for later assaults	Rejected plaintiff’s hindsight/strict-liability argument; undisputed record shows reasonable decision-making
Qualified immunity (as basis for summary judgment in district court)	N/A on appeal (plaintiff primarily argues merits)	District court held Dr. Nguyen entitled to qualified immunity because violation was not clearly established	Ninth Circuit did not reach qualified immunity as it resolved the appeal on the merits, affirming judgment for Dr. Nguyen
