No obligation to seek clarification of a non-party witness

Arunasalam v. Guglietti Estate, [2010] O.J. No. 3303 (S.C.J.)

The question to be answered in this motion with respect to refusals on examination for discovery was this: when counsel provides a summary of the anticipated evidence of a witness, is counsel required to seek clarification or further information from that witness?

Master Short held that although counsel must provide a summary of the substance of the evidence of a non-party witness, that obligation does not extend to obtaining further particulars and clarification. If the non-party witness is unwilling to provide clarification or further information to counsel opposite, it may be appropriate to bring a motion under Rule 31.10 in order to compel discovery of the non-party.
