Section 15 — Possession of pecuniary resources not accounted for

In a trial for an offence under this Act, the fact that a person—

(a) is in possession of pecuniary resources or property for which he cannot satisfactorily account and which is disproportionate to his known sources of income; or

(b) that he had at or about the time of the alleged offence obtained an accretion to his pecuniary resources or property for which he cannot satisfactorily account,

may be proved and may be taken into consideration by the High Court as corroborating the testimony of a witness in the trial.
