Abuse of customs powers can attract prosecution, imprisonment or fines for collusion, vexatious searches and unauthorised disclosures. Offences by customs officers criminalise abuse of office, collusion or connivance in fraudulent export or evasion of duty and prohibitions, punishable by imprisonment and fine. Vexatious searches or arrests-conducting searches, requiring searches, or making arrests without reasonable belief-are separately punishable, as is unauthorized disclosure of official particulars except when acting in good faith or under lawful requisition.
