Clause 54

If a person ordered to give security under section 41 or 50 fails to do so by the date on which the period for the security is to begin, the court may commit him to prison for a period not exceeding the period for which the security is ordered to be given.

If the person referred to in subsection (1) is already in prison, he shall stay there until the end of the term that the court has determined under subsection (1) or until he gives the security as ordered, whichever is the earlier.
