One issue that arises periodically in personal injury cases is whether a party must produce counsel's letter of instruction to its expert. In Nikolakakos v. Hoque, 2015 ONSC 4738 (S.C.J.), Master Graham considered whether the defendant was required to produce the letter of instruction to the plaintiff in advance of the plaintiff attending an independent medical examination.
Master Graham held that the instructing letter does not have to be produced until the party elects to call the expert at trial. Even after the report is served, the instructing letter does not have to be produced pending the defendant's decision whether to call the expert at trial. As a result, the defendant did not have to produce the letter of instruction in advance of the independent medical examination.
