Application of these Principles
37 In each of these cases, entry upon the land was necessary in order to accomplish the purpose, which was then put forward as the lawful excuse. Morris v Darby (the attempt to obtain evidence for divorce proceedings), Darcey v Pre-Term Foundation Clinic (the attempt to obtain evidence of illegal abortion), and Minkley v Monroe (the need for the journalist to demonstrate the absence of security), are all cases where the person charged was obliged to trespass in order to fulfil the purpose. The fulfilment of that purpose, however, was not a lawful excuse. The fact that their ultimate purpose was not criminal did not make the trespass excusable. In none of these cases did the defendant have a right to enter the premises in order to accomplish his purpose.
38 Applying these principles, it can be seen, with respect, that the Local Court was wrong. First, unlike the examples just given, entry to the premises by these defendants was not necessary to accomplish their purpose. Their purpose was to show their opposition to the proposed road. They could have protested outside the perimeter fence. Such a protest may not have been as dramatic, but that cannot matter. Were it otherwise, a person could invade another's property because their purpose might be better accomplished in that location rather than elsewhere. Upon that basis someone would be entitled to enter inclosed land, publicly or privately held, to sunbathe, or hold a dinner party, because they preferred that location to another area, not enclosed.
39 Secondly, the person who entered the land, in each of the cases referred to, did not have a criminal purpose. That, however, is not determinative, although it is relevant. Effecting entry itself may involve a crime (such as malicious damage to the fence). It would obviously be relevant for the prosecution to prove that the defendants had committed a crime in gaining entry, or intended to commit a crime once on the premises. In either case, and certainly in the latter case, it is difficult to see how a person who entered in such circumstances could assert that they had a lawful excuse. It is possible, perhaps, to imagine circumstances of necessity where beyond the fence there is a person in distress, such that damage to the fence, and entry, is necessary to alleviate that distress. Damage to the fence in such circumstances would not be malicious. Such person, in any event, would have lawful excuse for entry (cf the defence of necessity).
40 Returning to the present matter, the local Magistrate identified the purpose (peaceful protest), and the fact that it was not criminal, and determined the matter upon that basis. The issue was, however, whether that purpose in that location (on another's "inclosed land") was a lawful excuse. That question has not been addressed. In my view, the limits of those excuses which may be characterised as lawful excuses for the purposes of s 4(1) of the Act, are to be found by analogy with the categories which apply in civil trespass, supplemented by honest and reasonable mistake, where the facts assumed would, if true, give a right of entry.
