Provision may be made by a development order for securing that, in the case of decisions of a local planning authority of such classes as may be prescribed by the order, being decisions relating to the design or external appearance of buildings or other similar matters, any appeal under section 36 of this Act shall lie to an independent tribunal constituted in accordance with the provisions of that order, instead of being an appeal to the Secretary of State; and in relation to any such appeal the provisions of that section (except subsections (7) and (8) and, in subsection (5) thereof, the references to sections 27 and 29(3) of this Act) and the provisions of section 37 of this Act shall apply, subject to such adaptations and modifications as may be specified in the order, as they apply in relation to appeals to the Secretary of State under the said section 36.
If any tribunal is constituted in accordance with subsection (1) of this section, the Secretary of State may pay to the chairman and members of the tribunal such remuneration, whether by way of salaries or by way of fees, and such reasonable allowances in respect of expenses properly incurred in the performance of their duties, as the Minister for the Civil Service may determine.
