On an appeal against an improvement notice, the court may either cancel or affirm the notice and, if it affirms it, may do so either in its original form or with such modifications as the court may in the circumstances think fit.

Where, apart from this subsection, any period specified in an improvement notice would include any day on which an appeal against that notice is pending, that day shall be excluded from that period.

An appeal shall be regarded as pending for the purposes of subsection (2) above until it is finally disposed of, is withdrawn or is struck out for want of prosecution.
