Where, at any time after the end of the period for compliance with an enforcement notice, any step required by the notice to be taken has not been taken or any activity required by the notice to cease is being carried on, the person who is then the owner of the land is in breach of the notice.

Where the owner of the land is in breach of an enforcement notice that person shall be guilty of an offence.

In proceedings against any person for an offence under subsection (2), it shall be a defence to show that that person did everything that person could be expected to do to secure compliance with the notice.

A person who has control of or an estate in the land to which an enforcement notice relates (other than the owner) must not carry on any activity which is required by the notice to cease or cause or permit such an activity to be carried on.

A person who, at any time after the end of the period for compliance with the notice, contravenes subsection (4) shall be guilty of an offence.

An offence under subsection (2) or (5) may be charged by reference to any day or longer period of time and a person may be convicted of a second or subsequent offence under the subsection in question by reference to any period of time following the preceding conviction for such an offence.

In determining the amount of any fine to be imposed on a person convicted of an offence under this section, the court must in particular have regard to any financial benefit which has accrued or appears likely to accrue to that person in consequence of the offence.
