Patterson v. City of Danville, 875 S.E.2d 65

In November 2016 Langston Patterson entered the Danville Adult Detention Center (DADC) with known medical conditions (diabetes, hypertension, psychiatric disorder) and received ongoing care from Dr. Laurence Shu-Chung Wang.
Dr. Wang examined Patterson multiple times, ordered labs, prescribed medications, and arranged a November 11 hospital transfer for hyponatremia that resolved; Patterson later experienced altered mental status and received psychotropic treatments; he suffered cardiac arrest on February 20, 2017, never regained consciousness, and died months later.
Dr. Wang was paid hourly by the City, required to treat DADC inmates, used City facilities, equipment, records, and a City-contracted pharmacy; he met regularly with the DADC director and was governed by statutory and Board of Corrections policies.
The estate sued Dr. Wang for ordinary negligence and gross negligence. The circuit court held Dr. Wang derivatively immune from the ordinary negligence claim (plea in bar) and sustained a demurrer to the gross-negligence claim as insufficiently pleaded.
The Supreme Court of Virginia reviewed the ore tenus factual findings in the light most favorable to Dr. Wang and affirmed both holdings: derivative sovereign immunity applies and gross-negligence allegations were legally insufficient.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Dr. Wang is entitled to derivative sovereign immunity for negligence	Patterson: Dr. Wang was a private physician or not sufficiently controlled by the City, so no derivative immunity	Dr. Wang: He acted as the City’s agent performing a governmental function; City controlled patients, place, equipment, records, pay, and policies	Court: Derivative sovereign immunity applies — all four Messina factors satisfied
Whether complaint pleaded gross negligence sufficient to defeat immunity	Patterson: Misdiagnosis/failure to treat hyponatremia was gross negligence	Dr. Wang: Complaint alleges multiple treatments showing some care; allegations do not meet gross-negligence standard	Court: Demurrer sustained — allegations show some degree of care and do not state gross negligence
