R. v. Underwood (1998), 121 C.C.C. (3d) 117 (S.C.C. – Lamer)

Para. 9: “…[T]he situation can be resolved by holding a voir dire before the defence opens its case. In this voir dire, the defence will reveal the evidence which it intends to call, either through calling witnesses, or through agreed statements of fact. The trial judge can then consider the factors set out in Corbett (the nature of the previous convictions, the time since the previous convictions, and any attacks made on the credibility of Crown witnesses) in the context of the defence evidence, and make a final ruling on the Corbett application.”
