s 170 Execution and cost of works required by section 168 notice.
(1) If, within the period specified in a notice under section 168(1) for compliance with it, or within such extended period as the planning authority may allow, any trees which are required to be planted by a notice under that section have not been planted, the planning authority may— (a) enter the land and plant those trees, and (b) recover from the person who is then the owner or lessee of the land any expenses reasonably incurred by them in doing so. (2) If the person mentioned in subsection (1)(b) was entitled to appeal to the Secretary of State but did not do so, he shall not be entitled in proceedings under that subsection to dispute the validity of the action taken in accordance with the notice by the planning authority. (3) In computing the amount of the expenses which may be recovered by them under subsection (1), a planning authority may include in that amount such proportion of their administrative expenses as seems to them to be appropriate. (4) Where a notice under section 168(1) has been served— (a) any expenses incurred by the owner, lessee or occupier of any land for the purpose of complying with the notice, and (b) any sums paid by the owner or lessee of any land under subsection (1) in respect of expenses incurred by the planning authority in planting trees required by such a notice to be planted, shall be recoverable from the person responsible for the cutting down, destruction or removal of the original tree or trees. (5) If on a complaint by the owner of any land it appears to the sheriff that the occupier of the land is preventing the owner from carrying out work required to be carried out by a notice under section 168(1), the sheriff may by warrant authorise the owner to go on to the land and carry out the work. (6) A planning authority taking steps under subsection (1) may sell any materials removed by them from the land unless those materials are claimed by the owner within 3 days of their removal by the planning authority. (7) Where such materials have been sold the planning authority shall pay the owner the proceeds of the sale after deducting any expenses recoverable by them from him. (8) Where a planning authority seek under subsection (1) to recover any expenses from a person on the basis that he is the owner of any land, and such person proves that— (a) he is receiving the rent in respect of that land merely as trustee, tutor, curator, factor or agent of some other person, and (b) he has not, and since the date of the service on him of the demand for payment has not had, in his hands on behalf of that other person sufficient money to discharge the whole demand of the authority, his liability shall be limited to the total amount of the money which he has or has had in his hands on behalf of that other person. (9) A planning authority who by reason of subsection (8) have not recovered the whole of any such expenses from a trustee, tutor, curator, factor or agent may recover any unpaid balance from the person on whose behalf the rent is received. (10) Any person who wilfully obstructs a person acting in the exercise of the power conferred by subsection (1) shall be guilty of an offence and liable on summary conviction to a fine not exceeding level 3 on the standard scale.
