The learned judge, after considering the testimonies of PW6, the raiding officer, and PW4, the chemist, was satisfied with their explanations and therefore accepted that the chain of custody was intact. Having reviewed those factual findings and the reasons provided by the learned judge, we find that the appellant has failed to demonstrate any error on the part of the judge in reaching his conclusion. We concur with the learned judge that the exhibits seized by PW6, handed over to PW7, subsequently delivered to PW4, and later presented in court as evidence were indeed the same exhibits. Of particular importance is that PW6 and PW7 confirmed that the markings, signatures, and dates on the exhibits were made by them. The exhibits were sealed, labelled, and matched to the seizure documentation. The entire process, from seizure to inventory, handover, analysis, and resealing, was documented correctly. There is no evidence suggesting substitution or irregularity. We therefore find this issue to be unmeritorious.
