(1) The provisions of this regulation apply in relation to an appeal brought by any person under section 80(3) of the 1990 Act against an abatement notice served upon him by a local authority.
(2) The grounds on which a person served with such a notice may appeal under section 80(3) are any one or more of the following grounds that are appropriate in the circumstances of the particular case—
(a) that the abatement notice is not justified by section 80(3) of the 1990 Act;
(b) that there has been some informality, defect or error in, or in connection with, the abatement notice;
(c) that the authority have refused unreasonably to accept compliance with alternative requirements, or that the requirements of the abatement notice are otherwise unreasonable in character or extent, or are unnecessary;
(d) that the time, or, where more than one time is specified, any of the times, within which the requirements of the abatement notice are to be complied with is not reasonably sufficient for the purpose;
(e) where the nuisance to which the notice relates —
(i) is a nuisance falling within section 79(1)(a), (d), (e), (f) or (g) of the 1990 Act and arises on industrial, trade or business premises, or
(ii) is a nuisance falling within section 79(1)(b) of the 1990 Act and the smoke is emitted from a chimney,
that the best practicable means were used to prevent, or to counteract the effects of, the nuisance;
(f) that, in the case of a nuisance under section 79(1)(g) of the 1990 Act, the requirements imposed by the abatement notice by virtue of section 80(1)(a) of that Act are more onerous than the requirements for the time being in force, in relation to the noise to which the notice relates, of—
(i) any notice served under section 60 or 66 of the 1974 Act, or
(ii) any consent given under section 61 or 65 of the 1974 Act, or
(iii) any determination made under section 67 of the 1974 Act;
(g) that the abatement notice should have been served on some person instead of the appellant, being —
(i) the person responsible for the nuisance, or
(ii) in the case of a nuisance arising from any defect of a structural character, the owner of the premises, or
(iii) in the case where the person responsible for the nuisance cannot be found or the nuisance has not yet occurred, the owner or occupier of the premises;
(h) that the abatement notice might lawfully have been served on some person instead of the appellant being —
(i) in the case where the appellant is the owner of the premises, the occupier of the premises, or
(ii) in the case where the appellant is the occupier of the premises, the owner of the premises,
and that it would have been equitable for it to have been so served;
(i) that the abatement notice might lawfully have been served on some person in addition to the appellant, being —
(i) a person also responsible for the nuisance,
(ii) a person who is also an owner of the premises, or
(iii) a person who is also an occupier of the premises,
and that it would have been equitable for it to have been so served.
(3) If and so far as an appeal is based on the ground of some informality, defect or error in, or in connection with, the abatement notice, the court shall dismiss the appeal if it is satisfied that the informality, defect or error was not a material one.
(4) Where the grounds upon which an appeal is brought include a ground specified in paragraph (2)(h) or (i) above, the appellant shall serve a copy of his notice of appeal on any other person referred to, and in the case of any appeal to which this regulation applies he may serve a copy of his notice of appeal on any other person having an estate or interest in the premises in question.
(5) On the hearing of the appeal the court may—
(a) quash the abatement notice to which the appeal relates, or
(b) vary the abatement notice in favour of the appellant in such manner as it thinks fit, or
(c) dismiss the appeal;
and an abatement notice that is varied under sub-paragraph (b) above shall be final and shall otherwise have effect, as so varied, as if it had been so made by the local authority.
(6) Subject to paragraph (7) below, on the hearing of an appeal the court may make such order as it thinks fit—
(a) with respect to the person by whom any work is to be executed and the contribution to be made by any person towards the cost of the work, or
(b) as to the proportions in which any expenses which may become recoverable by the authority under Part III of the 1990 Act are to be borne by the appellant and by any other person.
(7) In exercising its powers under paragraph (6) above, the court—
(a) shall have regard, as between an owner and an occupier, to the terms and conditions, whether contractual or statutory, of any relevant tenancy and to the nature of the works required, and
(b) shall be satisfied before it imposes any requirement thereunder on any person other than the appellant, that that person has received a copy of the notice of appeal in pursuance of paragraph (4) above.
