The Pennsylvania Supreme Court is mulling a decision if health care providers can be held liable under the Mental Health Procedures Act for denying treatment to a man, who later killed his girlfriend, when there was no written application for voluntary inpatient treatment.

The Pennsylvania Supreme Court agreed to hear oral arguments Tuesday in Matos v. Geisinger. The petitioners, Alley Medical Center, David Y. Go, Kyle C. Maza, Geisinger Medical Center, Michael H. Fitzpatrick and Richard T. Davies Jr., challenged the state Superior Court’s decision denying their motion for summary judgment, arguing they were immune from liability under Section 114(a) of the MHPA, 50 P.S. 7114(a).
