Restriction on bail requires public prosecutor opportunity to oppose and judicial satisfaction before release. For customs offences punishable by imprisonment of three years or more under section 135, bail is barred unless the public prosecutor is afforded an opportunity to oppose and, if opposition is made, the Magistrate is satisfied there are reasonable grounds to believe the accused is not guilty and will not reoffend; Magistrates may nonetheless grant bail to persons under eighteen, women, or the sick or infirm. Additionally, police may investigate such offences only when specifically authorised by the Central Government, subject to conditions.
