The course opens with the power to search persons under Section 100 — the conditions under which a customs officer may search a person at or near a customs barrier, the requirement of reason to believe that the person is concealing goods liable to confiscation or relevant documents, and the mandatory requirement that the search of a woman be conducted only by a female officer. Section 101 covers the search of persons on vessels or aircraft who are suspected of secreting goods on their person, and Section 102 addresses the more intrusive power to detain and examine a person suspected of secreting goods within their body — requiring production before a gazetted officer for authorisation, a significant procedural safeguard that CBLE tests. The course explains why these three sections form a graduated power structure — open search, body surface search, and internal examination — and the different officer levels and conditions applicable to each.

Section 103 is covered as the general power to search any place where goods liable to confiscation or relevant documents are believed to be secreted, operating as a broader authority than the person-specific powers in Sections 100–102. Section 105 — the power to search premises — is explained as the primary provision for searching warehouses, offices, and residences, covering the authorisation requirement, the power to break open locks, the procedure for conducting a panchanama, and the legal significance of the panchanama as evidence in subsequent proceedings. Section 106 covers the power to stop and search conveyances — vessels, vehicles, and aircraft — including the power to compel an aircraft to land, and the conditions under which this power may be exercised without prior authorisation.

Section 104 — the power of arrest — is treated as a core CBLE provision: the officer level empowered to arrest, the requirement of reason to believe involvement in an offence punishable with imprisonment, the obligation to produce the arrested person before a magistrate within 24 hours, the distinction between bailable and non-bailable offences under the Customs Act and how bail applies in the customs context, and the rights of the arrested person. Section 107 covers the power to examine any person acquainted with the facts of a case, and Section 108 — the summons power — is treated with particular care: the power of any gazetted officer to summon any person for evidence or document production, the legal obligation on the summoned person to appear and answer truthfully, and the evidentiary status of statements recorded under Section 108, since the admissibility and retractability of Section 108 statements is a high-frequency CBLE topic.

Section 110 — seizure of goods, documents and things — is covered in full: the trigger condition of reason to believe goods are liable to confiscation, the procedure for seizure, the obligation to issue a notice within the prescribed period after seizure, the extended period where the investigation is not complete, and the provision for perishable goods. Section 110A — provisional release of seized goods — explains the mechanism by which seized goods may be released to the owner pending adjudication, the bond and security requirements, and the conditions under which provisional release may be refused.
