CMB v Mental Health Tribunal [2021] TASFC 4.
Section 40(b) is concerned with what is "likely". When that word is used in legislation, it can have various meanings. It can mean "more probable than not" or "more than a 50% chance". It can refer to something that might well happen. It can refer to a possibility that is more than a remote or theoretical possibility. The meaning of the word has been considered in a great many cases. See, for example, Boughey v The Queen (1986) 161 CLR 10; Tillmanns Butcheries Pty Ltd v Australasian Meat Industry Employees' Union [1979] FCA 85; (1979) 42 FLR 331 at 339; Cream Holdings Ltd v Banerjee [2003] EWCA Civ 103; [2003] 3 WLR 999. Much depends on the legislative context. It is significant that the principal purpose or object of s 40(b) is the protection of mentally ill persons and others from risks of harm. Having regard to the purpose and context of the provision, I consider that "likely" should be given a wide interpretation. It should not be interpreted as meaning "more probable than not". It must be interpreted as meaning something more than a remote or theoretical possibility. I think it should be interpreted as referring to something that might well happen. Having regard to the evidence that I have referred to, I consider that it was open to the Tribunal to conclude that, without treatment, the appellant's mental illness was "likely" to result in her killing herself.
