Extent to which right may be exercised
98.—(1)  The right of private defence does not extend to the inflicting of more harm than it is reasonably necessary in the circumstances.
[15/2019]
(2)  There is no right of private defence in cases in which there is reasonable opportunity to have recourse to the protection of a public authority in the circumstances.
Illustrations
     (a)  Z ambushes A in a secluded area and attempts to kill A. A kills Z while fending off Z’s attack. A is guilty of no offence because, in the circumstances, A had no reasonable opportunity to have recourse to the protection of a public authority.
     (b)  Z ambushes A in a secluded area and attempts to kill A. A’s right of private defence arises because, at that point of time, A had no reasonable opportunity to have recourse to the protection of a public authority. In the midst of the struggle between A and Z, a police patrol car arrives on the scene. A’s right of private defence ceases the moment A had reasonable opportunity to have recourse to the protection of the police.
