The binding legal principles established are: (1) A search without warrant is lawful under section 51(1)(b) of the Criminal Procedure and Evidence Act where: (i) a police officer has reasonable grounds to believe a warrant would be issued if applied for; and (ii) delay in obtaining a warrant would defeat the object of the search. Both requirements must be satisfied. (2) Evidence obtained through a lawful warrantless search is admissible. (3) Where an accused simply denies possession of contraband (rather than alleging substitution), the prosecution need not provide exhaustive documentation of every stage of the chain of custody; it is sufficient to show through witness testimony that the exhibits were handled by authorized persons with accountability at each stage and remained in tamper-proof containers. (4) Sealed, tamper-proof evidence bags that display indicators of whether they have been opened provide sufficient assurance of exhibit integrity. (5) Multiple handovers of exhibits between police officers does not break the chain of custody where all handlers are identified, their roles explained, and proper procedures followed. (6) Allegations of police fabrication or conspiracy must be substantiated with particulars; bare, unsubstantiated allegations without corroboration are insufficient to raise reasonable doubt. (7) Similar wording in police statements does not establish collusion where officers worked together on the same investigation; corroboration is expected. (8) In sentencing for drug possession, a court may properly consider as aggravation evidence suggesting intent to deal (such as commercial quantities, scales, packaging materials, and sachets) even where the conviction is only for possession. (9) Possession of dangerous drugs in a public place attracts a presumptive penalty of 3 years imprisonment under the Criminal Procedure (Sentencing Guidelines) Regulations, 2023. (10) While courts should consider non-custodial options for sentences under 24 months, failure to explicitly do so does not vitiate an otherwise appropriate and deserved sentence, particularly for serious offenses.
