Can expert rebuttal evidence be given in the absence of a written opinion?

British Columbia, Canada


The following excerpt is from Mayenburg v. Lu, 2009 BCSC 1308 (CanLII):

It has been held that under Rule 40A expert rebuttal evidence may be given in the absence of an advance written opinion: see, for example, Kelly v. Kelly, 20 B.C.L.R. (3d) 232. However, I think this must be subject to some control by the trial judge on the grounds of fairness and prejudice to the opposing party. This is especially so in a Rule 68 trial which emphasizes advance disclosure.
