An extension of an involuntary commitment under section 303 of the Mental Health Procedures Act, 50 Pa.C.S. 7303, requires clear and convincing evidence that the person is a danger to herself and others. The commitment order is not moot and is appealable even though the patient is no longer in custody because the sufficiency of evidence for a temporary commitment is a legal question that is “capable of repetition and yet apt to evade review.” In this case, the testimony of the doctor showed only “the mere presence of mental illness” and insufficient facts to prove a danger of self-harm.
