It is not necessary that it is only that person who carried out the function on behalf of the company that must testify. Not at all, as any official of the company well equipped with the transaction and or related documents would suffice to testify. – Peter-Odili JSC. Chemiron v. Stabilini (2018)
EVERY RELEVANT EVIDENCE IS ADMISSIBLE
Once a piece of evidence is relevant, it is admissible in evidence irrespective of how it was obtained.
– M.L. Garba JCA. Odogwu v. Vivian (2009) – CA/PH/345/05
