The primary judge's decision
45 The respondent submitted to her Honour that her arrest was unlawful because first, there were no reasonable grounds for her arrest and, second, she was neither told that she was under arrest nor given any reasons for her arrest. As to the first of these issues, her Honour referred to s 352 of the Crimes Act 1900 which relevantly authorises an arrest where the police officer, with reasonable cause, suspects a person of having committed an offence. Her Honour was satisfied that the matters of which Superintendent Little was aware at the time of the respondent's arrest were such as to provide a reasonable suspicion on which he was entitled to act under s 352 to effect that arrest.
46 However, the second ground upon which the respondent relied to allege that her arrest was unlawful was that she was neither told that she was under arrest nor was she given any reasons for her arrest. It was common ground that this was so. However, the appellant submitted to her Honour and repeated on the appeal that the officers had satisfied the third proposition articulated by Viscount Simon in Christie v Leachinsky [1947] AC 573 at 587-588, where his Lordship said, after reviewing the authorities, that they established the following propositions:
"(1) If a policeman arrests without warrant upon reasonable suspicion of felony, or of other crime of a sort which does not require a warrant, he must in ordinary circumstances inform the person arrested of the true ground of arrest. He is not entitled to keep the reason to himself or to give a reason which is not the true reason. In other words a citizen is entitled to know on what charge or on suspicion of what crime he is seized. (2) If the citizen is not so informed but is nevertheless seized, the policeman, apart from certain exceptions, is liable for false imprisonment. (3) The requirement that the person arrested should be informed of the reason why he is seized naturally does not exist if the circumstances are such that he must know the general nature of the alleged offence for which he is detained . (4) The requirement that he should be so informed does not mean that technical or precise language need be used. The matter is a matter of substance, and turns on the elementary proposition that in this country a person is, prima facie, entitled to his freedom and is only required to submit to restraints on his freedom if he knows in substance the reason why it is claimed that this restraint should be imposed. (5) The person arrested cannot complain that he has not been supplied with the above information as and when he should be, if he himself produces the situation which makes it practically impossible to inform him, eg, by immediate counter-attack or by running away. … If a policeman who entertained a reasonable suspicion that X has committed a felony were at liberty to arrest him and march him off to a police station without giving any explanation of why he was doing this, the prima facie right of personal liberty would be gravely infringed." (Emphasis added)
47 Lord Simonds spoke to the same effect (at 591-593) when he observed:
"Putting first things first, I would say that it is the right of every citizen to be free from arrest unless there is in some other citizen, whether a constable or not, the right to arrest him. And I would say next that it is the corollary of the right of every citizen to be thus free from arrest that he should be entitled to resist arrest unless that arrest is lawful. How can these rights be reconciled with the proposition that he may be arrested without knowing why he is arrested? ... Is citizen A bound to submit unresistingly to arrest by citizen B in ignorance of the charge made against him? I think, my Lords, that cannot be the law of England. Blind, unquestioning obedience is the law of tyrants and of slaves: it does not yet flourish on English soil. I would, therefore, submit the general proposition that it is a condition of lawful arrest that the man arrested should be entitled to know why he is arrested, and then, since the affairs of life seldom admit an absolute standard or an unqualified proposition, see whether any qualification is of necessity imposed upon it."
48 Lord Simonds then considered what qualifications, if any, must be imposed upon the fundamental rule that he had articulated. His Lordship expressed one such qualification in the following terms (at 593):
"Again, I think it is clear that there is no need for the constable to explain the reason of arrest if the arrested man is caught red-handed and the crime is patent to high Heaven... These and similar considerations lead me to the view that it is not an essential condition of lawful arrest that the constable should at the time of arrest formulate any charge at all, much less the charge which may ultimately be found in the indictment. But this, and this only, is the qualification which I would impose upon the general proposition. It leaves untouched the principle, which lies at the heart of the matter, that the arrested man is entitled to be told what is the act for which he is arrested. The 'charge' ultimately made will depend upon the view taken by the law of his act. In ninety-nine cases out of a hundred the same words may be used to define the charge or describe the act, nor is any technical precision necessary: for instance, if the act constituting the crime is the killing of another man, it will be immaterial that the arrest is for murder and at a later hour the charge of manslaughter is substituted. The arrested man is left in no doubt that the arrest is for that killing. This is I think, the fundamental principle, viz., that a man is entitled to know what, in the words of Lawrence LJ are 'the facts which are said to constitute a crime on his part'. "
49 The primary judge then referred to the decision of this Court in Adams v Kennedy [2000] NSWCA 152; (2000) 49 NSWLR 78 where it was held, applying Christie, that it was a condition of lawful arrest that the person arrested should be entitled to know why he is arrested. The leading judgment was delivered by Priestley JA with whom Sheller and Beazley JJA agreed. His Honour cited the passages from the speeches of Viscount Simon and Lord Simonds in Christie which I have set out above. To those passages he added (at 84 [33]) a reference to the speech of Lord du Parcq which included the following (at 600):
"The omission to tell a person who is arrested at, or within a reasonable time of, the arrest with what offence he is charged cannot be regarded as a mere irregularity. Arrest and imprisonment, without a warrant on a charge which does not justify arrest, are unlawful and, therefore, constitute false imprisonment, …"
50 In Adams, Priestley JA (at 84[24]) referred to the statements of the common law by Lords Simon, Simmonds and du Parcq as concerning
"the obligation to notify an arrested person of the charge for which the arrest was made."
51 His Honour concluded (at 85 [26]) that the common law as so stated in Christie was applicable in New South Wales subject only to any statutory alteration. None was identified.
52 It was therefore submitted to the primary judge that in the circumstances the respondent must have known the general nature of the alleged offence for which she had been arrested within the meaning of the third proposition enunciated by Viscount Simon in Christie. It was submitted that the respondent had heard and seen the others being arrested, that she had mopped up the blood in the apartment (although the police did not know that at that stage) and that she had been present during the murder. Accordingly, she knew the reason for her arrest.
53 The primary judge dealt with this submission in the following manner (at Red 25):
"The [respondent] did agree that when she heard the police tell Mark he was under arrest she understood it was in relation to the death of Paul Harris. She agreed that at that time she knew, because of what she had seen and because she had cleaned up some blood, that she could be in trouble.
However, I am not persuaded that any of the exceptions discussed in the cases apply. She was not caught red-handed. Whilst she may have understood in a general way the circumstances in relation to which the police were present, she could not know in any meaningful way the charge which was likely to be laid.
I am satisfied that [the respondent's] arrest was unlawful because she was not told that she was under arrest nor was she told the reasons for the arrest.
For the reasons I have already given I am satisfied that the [respondent] was then unlawfully detained until she was allowed to leave the police station alone at around 12.30."
54 On the question of damages, her Honour found (at Red 26) that on the day in question the respondent's liberty was restrained. She was anxious because she was not able to look after her daughter Rose and she had to care for her other daughter Jasmine within the restraints of the police station. In addition the appellant conceded that it had failed to comply with Pt 10A of the Crimes Act 1900, as a consequence of which the respondent was not informed of her rights on or after her arrest. Although Superintendent Little enumerated a number of reasons for that failure, her Honour was not persuaded that any of them excused his failure to comply with the Act. She accepted that this impacted upon the assessment of the respondent's damages.
55 As to general damages, her Honour rejected (at Red 27) the respondent's submission that she had ongoing psychological symptoms arising from the police officers' actions but nevertheless assessed general damages in the sum of $25,000 "taking into account my other findings".
56 As to aggravated damages, her Honour observed (at Red 27) that such damages were intended to compensate a plaintiff for conduct of the defendant which appeared to the plaintiff to be insulting or reprehensible. She accepted that such an award was appropriate in the present case
"where [the respondent] was kept with her child in a small room for some hours."
