"Person subject to involuntary admission on an outpatient basis" means:

(1) A person who would meet the criteria for admission on an inpatient basis as specified in Section 1-119 in the absence of treatment on an outpatient basis and for whom treatment on an outpatient basis can only be reasonably ensured by a court order mandating such treatment; or

(2) A person with a mental illness which, if left untreated, is reasonably expected to result in an increase in the symptoms caused by the illness to the point that the person would meet the criteria for commitment under Section 1-119, and whose mental illness has, on more than one occasion in the past, caused that person to refuse needed and appropriate mental health services in the community.
