Before or after imposing a fine on any person under section 55 of the Act for disobeying a witness summons or refusing to be sworn or give evidence, the judge may direct the court officer to give to that person notice that if he has any cause to show why a fine should not be or should not have been imposed on him, he may show cause in person or by witness statement or affidavit or otherwise on a day named in the notice, and the judge after considering the cause shown may make such order as he thinks fit.
