Explosives Act 1936

Where an offence against a provision of this Act is committed by a person by reason of a continuing act or omission—

the person is liable, in addition to the penalty otherwise applicable to the offence, to a penalty for each day during which the act or omission continues of not more than an amount equal to one-fifth of the maximum penalty prescribed for that offence; and

if the act or omission continues after the person is convicted of the offence, the person is guilty of a further offence against that provision and liable, in addition to a penalty otherwise applicable to the further offence, to a penalty for each day during which the act or omission continues after that conviction, of not more than an amount equal to one-fifth of the maximum penalty prescribed for that offence.

For the purposes of this section, an obligation to do something is to be regarded as continuing until the act is done notwithstanding that any period within which, or time before which, the act is required to be done has expired or passed.
