Is there an Enforceable Duty?
63The Summons filed by Mr Ritson seeks an order in the nature of mandamus requiring the defendant to perform his duty. The duty identified is said to arise from s 6 of the Police Act.
64Some comments are apposite here. First, the section relied upon does not actually use the terminology of a duty falling on a police officer.
65Secondly, the meaning of the word "duty" is often elusive. It very much depends upon the context in which it is being used. It may include either a specific legal obligation or a more general legal obligation. It includes a moral obligation, such as used in an expression like "a duty to help others less fortunate".
66The concept of a duty encompasses that which might be required to be done by reason of a position held, such as the duty of a toll collector to collect the toll. In that sense it is being used to echo the function being expected of a person occupying a position or office. In 1805, when Admiral Horatio Nelson signalled that "England expects that every man will do his duty", he was not using the word duty as anything more than the description of the function to be performed by all seamen of the British Fleet in the Battle of Trafalgar which was about to commence. Lieutenant Paul Nicholas of the Royal Marines, recorded his reaction, "... this emphatic injunction was received ...", and recorded the response as "... each bosom glowed with ardour at this appeal to individual valour". He too received it as a statement of the job he was to do. No question of a statutory basis arose.
67In such cases, there may not necessarily be a legal obligation so to do, because it may be a contractual obligation created by a contractual document such as a "Duty Statement" which accompanies a designated position.
68Thirdly, in considering legal authorities, it is necessary to keep in mind what kind of duty is being discussed.
69Speaking broadly, it has always been the tendency of courts to express a police officer's obligation in somewhat general terms. In Thomson v C [1989] NTSC 23; (1989) 95 FLR 116, Angel J said, at 117:
"Courts have sensibly been loath to clothe the ambit of a police officer's duty in specifics. Rather, their duties have always been expressed in the most general of terms."
70Cosgrove J in Innes v Weate (1984) 12 A Crim R 45 at 51, took a very similar approach when he said that a police officer's duty:
"... cannot be stated in other than general terms - the range of circumstances in which the duty to act may arise is too wide, too various, and too difficult to anticipate for the compilation of an exhaustive list."
71Statutory provisions may or may not create duties, depending on the words used, and the nature or type of duties being discussed. O'Keefe J said in Wilson v State of New South Wales [2001] NSWSC 869 at [41]; (2001) 53 NSWLR 407 at 416-417, that ss 6 and 7 of the Police Act, set goals after which each member of the police force is required to strive, but do not impose tortious duties of care owed to individuals in the community to fulfil all, or any, of the matters there set out: see also State of NSW v Tyszyk [2008] NSWCA 107 at [75] per Campbell JA (Mason P and Giles JA agreeing).
72Similar care needs to be exercised when considering what Basten JA said in Mohamed at [36]. Although his Honour described the imposition on a police officer of a duty to exercise their powers in a non-discriminatory way, he did not thereby state a general duty to carry out criminal investigations of a kind which would be enforceable, as is clear from his remarks in [49].
73This reflects the caution identified by Lord Denning MR in Reg v Commissioner of Police of the Metropolis; Ex Parte Blackburn [1968] 2 QB 118 at 136, where his Lordship discussed the consequences of any statement of an enforceable duty of a police officer:
"Although the chief officers of police are answerable to the law, there are many fields in which they have a discretion with which the law will not interfere. For instance, it is for the Commissioner of Police of the Metropolis, or the chief constable, as the case may be, to decide in any particular case whether inquiries should be pursued, or whether an arrest should be made, or a prosecution brought. It must be for him to decide on the disposition of his force and the concentration of his resources on any particular crime or area. No court can or should give him direction on such a matter. He can also make policy decisions and give effect to them, as, for instance, was often done when prosecutions were not brought for attempted suicide. But there are some policy decisions with which, I think, the courts in a case can, if necessary, interfere."
74Here, Mr Ritson argues that s 6 of the Police Act creates an enforceable duty upon every police officer, and thus the Commissioner, to investigate every complaint of a criminal offence alleged to be committed in New South Wales. I do not think that s 6 can be read in that way. Section 6 is a statement of the mission and functions of the NSW Police Force, and its members. It is in the most general of terms. To a very real extent, much of s 6 is a statement of the obvious. After all, what else would a police force, and its members, do if not to prevent and detect crime. That is their raison d'etre. But, read coherently, in the context of the Act, it is apparent that such a general statement of functions is necessarily subject to, at least, financial limits, and as well, the control of the Commissioner by the exercise of his powers in accordance with the responsibilities set out in s 8 of the Police Act.
75I am not persuaded that s 6 of the Police Act creates any obligation of the kind alleged by Mr Ritson. Nor am I persuaded that the common law has created an enforceable obligation falling on the Commissioner of the kind which Mr Ritson asserts.
76It has long been established that there needs to be a sound basis in law for an order for mandamus to issue. In 1852, Lord Campbell CJ refused an application for mandamus to compel the East India Company to pay the Army Commander, Lieutenant General Sir Charles Napier, the arrears of his pay. Lord Campbell said:
"... for the existence of a legal right or obligation is the foundation of every writ of mandamus. ... A legal obligation, which is the proper substratum of a mandamus, can only arise from common law, from statute, or from contract."
See: Ex parte Napier (1852) 18 QB 692 at 695.
77As I have found, the Police Act does not create a legal obligation, enforceable by mandamus. Mr Ritson does not suggest any other source for a legal obligation.
78In those circumstances, it is not open to the Court to make the orders sought in the Summons.
