(c) In other circumstances, however, offences that stem from an ill-advised and unnecessary arrest, may objectively be considered the anticipated or expected outcome and so "obtained" for the purposes of s.138. Carr is such a case.
81 The reservation that I have expressed in the preceding paragraph relates to the observation of Adams, J., that in the context of offences that are said to stem as an unintended consequence from an arrest, that there is a need to establish "conduct that was intended or expected (to a greater or lesser extent) to achieve the commission of offences" as a necessary and separate element in order to satisfy the notion of "obtained" in that context.
82 In the passages quoted from the judgment of Adams, J. set out in paragraphs [77] and [78] above, the proposition is advanced that in cases of the kind referred to in the preceding paragraph, the word "obtained" in s.138(1) requires, in addition to a causal nexus, that the impugned conduct must either be "intended" or "expected" to achieve the commission of offences. However, cases involving an ill-advised or unnecessary arrest which result in unintended consequential offences by definition lack a purposive element. In other words, offences stemming from such an arrest occur without any intention on the part of the arresting officer to provoke such offences. It is, for that reason, that I cannot agree with Adams, J. that in such cases the word "obtained" cannot be satisfied unless the causal nexus is also accompanied by "something more" in the nature of "intended" conduct. I do, however, with respect agree with his Honour's observation that in order in such cases for evidence to be "obtained", it may, in some such cases, be necessary that the conduct (the arrest) be of a kind that could be "expected" to give rise to the commission of further offences. The reference to an "expectation" by Adams, J. in Coe may, in some cases, be a material aspect and Robinett and Carr could, as his Honour observed, be seen as examples of that proposition.
