Fortunately, there is a terminal date in that case. If we look at the Northern Ireland (Emergency Provisions) Act 1973 we find under Section 30 (2): The provisions of this Act … shall remain in force until the expiry of one year beginning with its passing and shall then expire unless continued in force by an order under this section … all or any of the said provisions which are for the time being in force … shall continue in force for a period not exceeding one year from the coming into operation of the order.
