If it is not practicable after reasonable inquiry to ascertain the name or address of the person managing the house as so defined, the notice under this section may be served by addressing it to him by the description of " manager of the house " (naming the house to which it relates) and by delivering it to some person on the premises.
A notice under this section shall require the execution of the works within such period, being not less than twenty-one days from service of the notice, as may be specified in the notice, but that period may from time to time be extended by written permission of the local authority.
Where a local authority serve a notice on any person under this section they shall inform any other person who is to their knowledge an owner or lessee of the house of the fact that such a notice has been served.
A person on whom a notice is served under this section may, within twenty-one days of service of the notice, or within such longer period as the local authority may in writing allow, appeal to a magistrates' court on any of the following grounds which are appropriate in the circumstances of the particular case—
If and so far as an appeal under this section is based on the ground of some informality, defect or error in, or in connection with, the notice, the court shall dismiss the appeal if it is satisfied that the informality, defect, or error was not a material one.
Where the grounds on which an appeal is brought under this section include the ground specified in paragraph (e) of subsection (5) of this section, the appellant shall serve a copy of his notice of appeal on each other person referred to, and on the hearing of the appeal the court may make such order as it thinks fit with respect to the payment to be made by any such other person to the appellant, or, where the work is executed by the local authority, to the local authority.
