22. Use of force, where person unable to consent
Where a person is intoxicated or insensible, or is from any cause unable to give or withhold his or her consent, any force used in good faith and without negligence for purposes of medical or surgical treatment, or otherwise for his or her benefit is justifiable, unless the person authorised by him or her or by law to give or refuse such consent on his or her behalf objects to the use of such force.
