If at any time while a special hours certificate is in force no music and dancing licence or, as the case may be, no certificate under section 79 of this Act is in force for the premises to which or part of which the special hours certificate relates that certificate shall thereby be revoked.

Where a special hours certificate is revoked under subsection (2) of this section in consequence of a contravention of section 59 of this Act, no special hours certificate shall be valid in relation to the premises or part in question, if it is issued on an application made earlier than two months after the date of the revocation or made earlier than such later time, if any (not being more than twelve months after that date) as may be specified in the order revoking the certificate.

At any time while a special hours certificate for any premises or for part of any premises is in force, the chief officer of police may apply to the licensing justices or, if it was granted under section 78 of this Act, to the magistrates’ court, for the revocation of the certificate on the ground that the revocation is expedient by reason of the occurrence of disorderly or indecent conduct in the premises or part to which the certificate relates; and if the licensing justices or the magistrates’ court, as the case may be, are satisfied that the ground of the application is made out, they shall revoke the certificate.
