Another unreported court case adding to the range of ancillary acts allowed under Section 63 described earlier found it lawful to treat, with reasonable restraint if necessary, a 17-year-old woman with diabetes who was refusing her insulin therapy.8 The court accepted that the refusal of insulin treatment was part of self-harming behaviour which was a symptom of her mental disorder (a personality disorder). The gene discussed is INS; the disease is psychiatric disorder.
