Part 4: Police Powers Chapter 7: Maritime Enforcement: Northern Irish Offences
Chapter 7 provides for maritime enforcement powers equivalent to those set out in Chapter 5 of Part 4 to apply in Northern Ireland, but not including the powers of 'hot pursuit’, and taking account of Northern Irish law and practice. The powers are also limited to the territorial waters of Northern Ireland, unlike the provisions that apply in respect of Scotland and England and Wales.
	Section 32 of the Police (Northern Ireland) Act 2000 limits police jurisdiction throughout Northern Ireland and its adjacent UK waters within the seaward limits of the territorial sea in the same manner as section 30 of the 1996 Act applies in England and Wales. Within this jurisdiction, the main provisions in Chapter 7 provide Northern Ireland law enforcement officers with maritime specific powers to stop, board, detain and divert ships for the purpose of preventing, detecting or investigating an offence under the law of Northern Ireland. In particular, the powers may be exercised in relation to:
	a United Kingdom ship in Northern Ireland waters;
	a ship without nationality in Northern Ireland waters;
	a foreign ship in Northern Ireland waters; or
	a ship, registered under the law of a relevant territory, in Northern Ireland waters.
	The powers will be exercisable by a constable who is a member of the Police Service of Northern Ireland or the Police Service of Northern Ireland Reserve; a special constable in Northern Ireland by virtue of section 79 of the Harbours, Docks and Piers Clauses Act 1847; designated customs officials (as under Part 1 of the Borders, Citizenship and Immigration Act 2009); suitably designated NCA officers under the Crime and Courts Act 2013; or any person of a description specified in regulations made by the Secretary of State (made under section 107(3)(e)).
