40 It is in this context that the issue here lying between the parties as to the meaning of the phrase in question must be resolved.
41 There is no suggestion that anything which the respondent did involved a departure from the ordinary course of his duties, other than leaving his firearm in the vehicle and then failing to secure it in the gun room, when he went off shift. This was the 'something done' to which s 6(2) directs attention. In my view, that these errors, whether inadvertent or negligent, involved the respondent acting outside the ordinary course of his duties, so that exemption did not operate, may not be accepted. The phrase, 'acting in the ordinary course of a persons' duties' must be understood as encompassing the possibility of human error in performing a duty in the ordinary course.
42 This conclusion is reinforced by a consideration of the position of off duty police officers. In their case, the applicable guidelines are given regulatory force, the regulation 113 exemption in relation to licensing and permit obligations being subject to adherence to those guidelines. That approach has not been adopted in the case of the s 6(2)(a) exemption.
43 The reason for the differing approaches adopted to these exemptions can be understood by a consideration of a number of examples.
44 Departures from 'the ordinary course' of a police officer's duties when using a firearm can easily be envisaged. A police officer using a firearm to shoot a personal rival with whom the officer is having a dispute, is an obvious and extreme example of use of a firearm while not acting in the ordinary course of duty, albeit no doubt an extremely unlikely one. This is not a mere error committed in the ordinary course of duty, but a deliberate act entirely inconsistent with that duty. Even on the respondent's approach, such a situation would take the police officer's use of the firearm outside the ordinary course of duty.
45 As the plaintiff argued, departures from the policy which regulates carrying and securing firearms which would not take a police officer outside the ordinary course of duty, can also readily be envisaged. In some cases, while deliberate, they will not involve any error. Where a police officer is faced with two conflicting obligations, for example when called on to dive into a river to assist people trapped in a car, necessitating a firearm being left unsecured on a river bank, the resulting breach of the firearm policy could not result in the officer acting outside the ordinary course of duty.
46 Likewise, an error of judgment made when returning fire at an assailant who is shooting at a number of officers, which results in an officer shooting another police officer, could not result in a situation where the officer would no longer be acting in the ordinary course of duty, notwithstanding the serious consequences of the error made. An error of this kind could be inadvertent, or could even involve negligence.
47 Similarly, it seems to me, an error or oversight in securing a firearm after alighting from a police vehicle, may not result in a situation where the officer is no longer acting in the ordinary course of the officer's duties. The evidence does not reveal how the errors here in question came to become made. It may well be that failures like the respondent's involve a very serious breach of the applicable policy, which may be dealt with in various ways, but they do not take a police officer beyond the ordinary course of duty.
48 There may, of course, be other factual situations which could give rise to quite different conclusions. It could be, for example, that a police officer who deliberately refused to adhere to required policy in relation to the carrying and securing of firearms, could also be found no longer to be acting in the ordinary course of duty. Such a deliberate decision, like a deliberate decision to use a firearm to shoot a rival, while of a different character, may still lead to the same result, so far as the question of whether or not the officer is still acting in the ordinary course of duty, once that decision has been made, is concerned.
49 There is no suggestion that this was such a case. To the contrary, the evidence suggests there had been no history of breaches of the firearm policy and that this was a one-off error.
50 The policy requiring police officers to secure their firearms is no doubt directed at the same considerations as those which underpin the objects of the Firearms Act, namely, to ensure that the firearms which police officers are required to carry in the performance of their duties are safely and securely carried and stored. That policy is unquestionably an important one, especially given the statutory exemption for police officers who breach s 39 during the ordinary course of their duties. Undoubtedly a failure to adhere to the policy may be enforced by the Police Commissioner in various ways. Assuming here that the evidence established a breach of s 39, in the circumstances it is difficult to see that it is one which could result in a conviction for an offence under s 39, given the s 6(2)(a) exemption.
