CHAPTER 8. THE POLICE. ALTHOUGH the constable is an officer with powers long known to the Local Police common law and part of the special powers of the modern police Authorities officer are exercised by him as a constable, the professional police forces only date from the first half of the nineteenth century.1 The Metropolitan Police, whose jurisdiction extends over a fifteen- mile radius from Charing Cross is the only police force in the United Kingdom which is under the direct control of the Home Secretary, who is the police authority. The executive head is the Commissioner of Police for the Metropolis, who is appointed by the Crown and is the disciplinary authority. The Commissioner makes appointments and has powers of suspension and dismissal. The City of London Police are an independent force, but the appointment of the Com- missioner (Chief Officer) must be approved by the Home Secretary. The Court of Common Council is the police authority. Elsewhere in England and Wales the Police are organised as county or county borough forces. The local police authority for a county is the Standing Joint Committee, so called because its members are drawn half from the County Council and half from the Justices of Peace in Quarter Sessions, who had sole responsibility from 1839 when the county police force was first authorised until 1889 when the County Councils came into existence,2 In a county borough the authority is the Borough Council acting through the Watch Committee. The local authority determines the size of its force and has the powers of appointment and of dismissal; these powers are in counties exercised by the Chief Constable as disci- plinary authority; in boroughs they are exercised by the Watch Committee. The authority pays the salaries and wages of members of its force, though the scale of payments is fixed on a national basis. The central administrative control of the Home Secretary is Home important. The appointment of the chief officer of police (Chief Constable) by the police authority is subject to the approval of the Forces, Home Secretary. The Police Act, 1919, s. 4, provides that "it shall be lawful for the Secretary of State to make regulations as to the 1 For a short account of the histoiy of the police and parish constables, see Hart.
