Patient Held In a Mental Health Facility After the Court Order Authorizing Confinement Had Expired Was Entitled to Habeas Corpus Relief Pursuant to CPLR Article 70

The Court of Appeals, in a full-fledged opinion by Judge Stein, over a dissent, reversing the appellate division, determined that a patient, who was held in a mental health facility pursuant to a court order which the facility neglected to extend, was entitled to release pursuant to a CPLR article 70 habeas corpus proceeding. The hospital unsuccessfully argued that the only habeas-corpus relief available to the patient was pursuant to Mental Hygiene Law 33.15 which required an inquiry into the patient’s mental state:

CPLR 7001 provides that article 70 applies to common-law and statutory writs of habeas corpus “[e]xcept as otherwise prescribed by statute” (CPLR 7001). However, nothing in the plain language of Mental Hygiene Law § 33.15 purports to limit the availability of the common-law writ in Mental Hygiene Law proceedings. Rather, section 33.15 enhances the efficacy of the writ of habeas corpus, as our case law dictates, and thereby ensures that patients are not committed and retained without due process of law. That is, Mental Hygiene Law § 33.15 allows patients to seek a writ of habeas corpus when they are being held pursuant to a court order but, nevertheless, believe they have sufficiently recovered from their mental illness so that their continued retention is unwarranted; in such cases, determining the legality of their retention would require an inquiry into their mental state. On the other hand, patients whose detention is otherwise unauthorized may proceed under the habeas corpus provisions of CPLR article 70 since the legality of their detention can be determined on the basis of, for example, whether the appropriate procedures have been followed, without the need for a hearing into their mental state.  People ex rel.
