All of these cases precede the operation of LEPRA, that, although assented to on 29/11/02, did not commence by proclamation until 1/12/05. Whilst LEPRA allowed for the continuance of the common law in relation to the powers of a police officer and the execution of those powers (s.4) the Act had as its object and purpose that which was referred to by the Attorney General at the time in the second reading speech. Mr Debus said as follows:-
" This Bill represents significant law reform. It radically simplifies the law in relation to law enforcement powers, setting out in one document the most commonly used criminal law enforcement powers and their safeguards…matters included in the Bill represent a codification of the common law, a consolidation of the existing statute law, clarification of police powers or a combination of these. While generally the Bill simply re-enacts existing legislation, it does in some circumstances make amendments intended to more accurately reflect all areas of the common law and to address areas in the existing law where gaps have been identified. Unless expressly stated, the Bill is not intended to change the common law…" (Hansard, Legislative Assembly, 17/9/2002).
In my view s.99 codifies the powers of arrest. Use of the words "may" and "must not" delineate areas of discretion and obligation when a police officer exercises the power of arrest. I have found that Senior Constable Heather did not comply with s.99 and therefore the purported arrest was unlawful. S.99 was not in force when the circumstances with which these cases dealt occurred. Those cases of course will still provide guidance in a situation, for instance, with a charge that is being dealt with by the Court does not involve as an essential ingredient, such as the case in s.58, that a police officer be acting in the execution of his duty. For instance, if an accused had been charged pursuant to the provisions of s.61, and the events that took place that constituted the factual basis for the charge of common assault occurred during the continuance of an unlawful arrest, an accused may still be found to be guilty. However, the s.61 alleged assault would have occurred during the continuance of an unlawful arrest, and undoubtedly it would present a situation that would give rise to the Court having to consider the provisions of s.138, and whether or not the discretion allowed for under s.138 would be exercised in favour of the prosecution. The cases that I have referred to would provide guidance.
(c) There are no decisions of appellant courts that I have been able to find that deal with s.99 of LEPRA. There are a number of decisions of this Court and, in particular, the decision of Helpern LCM in P v McLean (2008) NSWLC 11, that deal with the effect of LEPRA and, in particular, the codification of the power of arrest provided for by s.99. His Honour's opinion in this decision is the same as mine. The benefit of this codification allows a Court, subject obviously to the vicissitudes of evidence and the consequential findings of fact, to arrive at a decision as to the lawfulness or otherwise of an arrest, i.e. whether or not it is in conformity with s.99. If the arrest is found to be unlawful after the relevant considerations, and the charge is one pursuant to the provisions of s.58, then the Prosecution will fail to establish an essential ingredient of the offence. However, if the charge laid against the defendant is otherwise, then a finding of unlawfulness of arrest will lead to a consideration of s.138 of the Evidence Act as I have said.
