[9] Rogers (1996) 86 A Crim R 542 at 546 - see also Gleeson CJ's remarks in Behrooz v Secretary of Department of Multicultural and Indigenous Affairs [2004] HCA 36; (2004) 219 CLR 486 at [15]: "One closely confined area in which the law has accepted a limited form of right to escape concerns the common law principle of necessity. In the Victorian case of R v Loughnan, and the New South Wales case of R v Rogers, consideration was given to the principles according to which a person, confronted in prison with some peril involving a threat to life or safety, may lawfully take steps, proportionate to the danger, to avoid the threat. Such steps do not ordinarily involve remaining at large in the community for an indefinite period. Thus, for example, there are United States authorities which make it a condition of pleading necessity as an excuse for escaping from prison that the prisoner, after escape, must report immediately to the proper authorities when he has attained a position of safety from the immediate threat. The Supreme Court of Victoria, in Loughnan, said this was a matter of evidentiary significance, rather than a legal condition. In Southwark London Borough Council v Williams, Edmund Davies LJ, discussing the defence of necessity, pointed out that "the law regards with the deepest suspicion any remedies of self-help, and permits those remedies to be resorted to only in very special circumstances". ... Where a situation of necessity arises, it may justify action taken by a prisoner or detainee to get out of harm's way, but it does not mean that the prisoner or detainee becomes free from all the constraints of custody, or may escape into the community and remain at large."
