2.3 Chain of Custody of Physical Evidences

The custody's chain — the evidence's documented journey: the collection (the officer, the time, the place); the packaging-and-sealing (the tamper-evidence); the labelling (the unique identification); the transport (the integrity's protection); the storage (the security-and-preservation); the analysis (the examiner's custody); the court's production (the seal's opening in court). The chain's law: the break's consequence — the admissibility-and-weight challenges (the tampering's suspicion; the Evidence Act's-and-procedure's authentication faces); the record's discipline (the custodial forms, the witnesses at every transfer). The exam's line: the science is only as good as the chain.
