Commentary on Sections Part 2: Networks, Services and the Radio Spectrum Chapter 2: Spectrum Use Section 157: Procedure for directions under s.156
358.An order containing a direction under section 156 must state its purpose, unless the direction requires OFCOM to reserve certain frequencies for specified uses or requires OFCOM to exercise their powers under the proviso to section 1(1) of the Wireless Telegraphy Act 1949 or under section 1, 3 or 3A of the Wireless Telegraphy Act 1998 in a certain way. Before making an order containing a direction under section 156, unless urgency makes it inexpedient to do so, the Secretary of State must consult OFCOM and such other persons as she thinks fit. A draft of the order must be laid before Parliament and approved by each House, except where the Secretary of State considers the urgency of the case requires the order to be made straight away. An order containing a direction given by the Secretary of State in an urgent case ceases to have effect at the end of 40 days (excluding Parliamentary recesses) unless it is approved by a resolution of each House of Parliament.
