Section 10: North-South co-operation and the prevention of new border arrangements
This section requires ministers and any devolved authority, when exercising any of the powers in the Act, to act compatibly with the Northern Ireland Act 1998 and have due regard to the joint report of 8 December 2017 from the negotiators of the EU and the UK on progress during phase 1 of negotiations under Article 50 of the Treaty on EU.
	The section also prevents the powers in sections 8, 9, 23(1) or 23(6) from being used to diminish any form of North-South cooperation (as provided for by the Belfast Agreement) or which would introduce any border arrangements (including physical infrastructure or checks and controls) on the land border between the United Kingdom and the Republic of Ireland, where such arrangements did not exist before exit day and are not in accordance with an agreement between the UK and the EU.
