The Shorter Oxford Dictionary gives as definitions:
"1. Loss or detriment caused by hurt or injury affecting a state, condition or circumstances ( arch.)
2. Injury, harm (ME).
36 To my mind, a common element to all of the authorities (with the possible exception of Henderson v Battley) is some physical change or alteration to the property, even though this may be temporary. I exclude from that the hypothetical exceptions mentioned by Green CJ in Ranicar because, as I have said, his Honour was there contemplating the notion of damage for the purpose of civil litigation, and in the context of two contractual documents, and not operating in the context of criminal legislation. I have no doubt that damage in the civil sense can be caused without physical injury.
37 That is not so where the criminal law is concerned. Even Henderson v Battley could, in a sense, be seen as involving some physical interference with the land. If it is not to be seen in that light, I would decline to follow that decision.
38 In my opinion, an essential element of "damage" for the purpose of s195 is, to use the words (or some of them) of Walters J in Samuels v Stubbs, "physical derangement" (though not necessarily permanent, or even lasting) to the property in question. It is the word "functional" that has given rise to the present argument. But I do not read his Honour's conclusion as meaning that temporary functional interference, without a physical interference with the property itself, could be sufficient to establish criminal damage. It is of some significance that in that case the evidence was that the policeman's cap had been jumped upon and crushed. That was ample evidence of physical derangement. In my opinion too much emphasis has been placed upon the word "functional" without it being seen in its complete and proper context. Interference with functionality alone, without "physical derangement" would, in my opinion, be insufficient to establish damage within the meaning of s 195. Interference with functionality could be proved, for example, by proof of the removal of a key to a motor vehicle, or the erection of physical barricades around a vehicle preventing its use. But here, in my opinion, while they might amount to some other offence, such interference would fall short of amounting to (malicious) damage.
39 It is true that a number of the other cases refer, in one way or another, to functionality. For example, in Zischke, one of the graffiti cases, the Court of Criminal Appeal in Queensland said:
"What emerges from a review of the decisions is that 'damage' may be held to have been done even though the injury to the article of property is not permanent but is remediable, if only by the expenditure of money. Probably the formula that most nearly embraces all the attempts at definition is that a thing is damaged if it is rendered imperfect or inoperative: see 'A' (a juvenile) v The Queen [1978] Crim LR 689. This would incidentally also serve to accommodate the decision in Samuels v Stubbs … where a conviction of damaging a policeman's cap was sustained by proof that the respondent had kicked it three times and then jumped on it, thus producing what was described as a 'temporary functional derangement' of the article in question."
40 I do not read this passage as excluding the need for the prosecution to prove some physical impact upon the property. In Zischke the accused had painted political material on buildings, footpaths and walls. The passage quoted was predicated upon the fact that the physical integrity of the property had suffered interference.
41 Moreover, "temporary functional derangement" could not be taken to express a definition of "damage"; a simple illustration will make the point. Scratching or denting the duco of a motor vehicle would, undoubtedly, amount to "damage"; but it does not render the motor vehicle inoperable and does not interfere with its functionality.
42 During the course of the hearing of the present proceedings, some debate took place concerning the boundaries of "damage" said to be occasioned to property. It was postulated that for a protestor to sit in front of or on a bulldozer could not amount to damage within s 195. That proposition is correct. In fact, it is not the action of the protestors that affects the operability of the machine; it is the (sensible) decision of the owners not to use it in circumstances where danger could be caused.
43 On behalf of the DPP it was argued that authority establishes that it is not necessary that there be any alteration in the physical nature of the property. Particular reliance was placed in this respect on Handerson v Battley, Rowe v Kingerlee and Ranicar v Frigmobile. I cannot accept that. I have already indicated that if Henderson does support that proposition, I would not follow it, but, in my opinion, the dumping of large quantities of rubble does physically affect, although temporarily, the surface of the land itself.
44 I am satisfied that, for a conviction to be made out under s 195, it is necessary that the prosecution establish, even to a limited degree, some physical interference or alteration to the property in question.
45 That calls for analysis of the evidence of what the defendants did.
46 In the statement of facts, it was said that they:
