I know you've covered most of the points, but there's also a criteria that needs to be met for any form of detention (and the legislation states you should always use the "least restrictive option")
The criteria is:
- The patient has a mental disorder.
- The patient has significantly impaired decision-making ability (see Appendix 2) with respect to medical treatment for mental disorder, as a result of his or her mental disorder.
- Detention in hospital is necessary to determine what medical treatment is required and to provide that treatment.
- Significant risk exists to the health, safety and welfare of the patient or to the safety of others if the patient is not detained.
- There are sufficient grounds for believing that granting of an STDC is necessary for a patient who is refusing to accept treatment on a voluntary basis.
There's numerous reasons why she wouldn't have met this criteria: that she wasn't actively self harming or posing a risk to herself/others; lack of diagnosis..or, of course, there's no treatment for being an attention seeking baw/Bush
