In affirming the dismissal of a complaint against a hospital for false imprisonment based on involuntary confinement pursuant to the Mental Hygiene Law, the Third Department explained the relevant analysis. Plaintiff had made death threats against family members:
Pursuant to the Mental Hygiene Law, an individual may be temporarily confined on an involuntary basis where he or she has “a mental illness for which immediate observation, care, and treatment in a hospital is appropriate and which is likely to result in serious harm to himself[, herself] or others” (Mental Hygiene Law § 9.39 [a]). We agree with Supreme Court that all of plaintiff’s claims against the hospital are, in effect, claims for false imprisonment, inasmuch as they are all based upon allegations of unlawful seizure and involuntary confinement… . These claims all turn upon a finding of medical malpractice because “[c]ommitment pursuant to Mental Hygiene Law article 9 is deemed privileged in the absence of medical malpractice”… . Accordingly, the hospital was required to make a prima facie showing that its medical treatment did not depart from accepted standards of care… .
