(3) Mitigating factors The mitigating factors to be taken into account in determining the appropriate sentence for an offence are as follows: …
(i) the remorse shown by the offender for the offence, but only if:
(i) the offender has provided evidence that he or she has accepted responsibility for his or her actions, and
(ii) the offender has acknowledged any injury, loss or damage caused by his or her actions or made reparation for such injury, loss or damage (or both),
...
10 What is the significance of the plea of guilty in light of this provision? In my opinion, although a plea of guilty is, in law, no more than an admission of the elements of the offence it is, as a matter of fact, an acceptance or acknowledgment of guilt for the offence. That it is formal does not change this inherent characteristic. The mere fact that there may be a dispute as to how that guilt came about, which is decided adversely to the offender, does not cause it to lose this characteristic. It follows that the plea of guilty is, inherently, "evidence that... [the offender] has accepted responsibility for his for her actions", the only relevant actions being those actions which gave rise to the offence. Similarly, where those actions have caused injury or loss, a plea which expressly or by necessary implication refers to such consequences, must logically constitute an acknowledgment of those consequences. The presence of these two factors provides some evidence of remorse. But it might not be persuasive evidence, depending on the circumstances.
11 The key notion conveyed by the concept of remorse is a commonsense one -- as shown by all the dictionary definitions -- it is regret or sorrow for the wrongdoing. In some cases, perhaps most, the plea of guilty will be motivated or at least accompanied by regret for the crime that has been committed. The extent of that regret will, to my mind, determine the extent of remorse and, hence (within limits) the extent of mitigation. Remorse that results in actions and not only words is plainly more significant. A plea of guilty where an admission of the offender provides, as a practical matter, the only evidence against him is an action of this kind, though, as it happens, it occurs by way of a word. In my view, these fundamental notions are part of ordinary human experience and, for a very long time, the criminal law, which ought not to be disregarded or confined by nice distinctions or technical qualifications.
12 It follows that, although the reason why an offender pleads guilty does not qualify its legal effect (though, of course, this might be material when he or she seeks to withdraw the plea), it remains significant in the assessment of the plea's significance as a potential mitigating factor. The Courts have, for example, always given very limited significance to a guilty plea as evidence of remorse where it appears to be motivated merely by acknowledgment of overwhelming evidence of guilt and, at the other end of the scale, considerable significance to a plea where evidence of guilt is exiguous or otherwise non-existent. A plea in the former circumstances may well be consistent with the presence of remorse but, without more, is scarcely significant evidence of remorse. There is no bright line that demonstrates the limits of remorse. It will always be a matter of degree. Even slight remorse is capable of some significance, though in the circumstances it might well not affect the sentence at all.
13 Remorse will often be relevant to a greater or lesser extent to the assessment of the prospects of rehabilitation. It does not seem to me that, in this context, s 21A(3)(i) is material, but I do not express any final view on this point.
