Reasons for judgement were released today (Pinch v. Hofstee) addressing the scope of expert instructions that need to be disclosed to make expert evidence admissible.  In short the Court noted that a “paraphrased summary of instructions” was insufficient.
In noting what Rule 11-6(1)(c) requires Mr. Justice Burnyeat provided the following reasons:

[1]             The parties presented a number of expert reports.  While some of the expert reports attached the instructions that were provided to the expert by counsel, some of the expert reports merely provided a paraphrased summary of instructions.

[2]             Rule 11‑6 of the Supreme Court Civil Rules provides that, for an expert report to be tendered in evidence, it must set out a number of matters including “the instructions provided to the expert in relation to the proceeding” [Rule 11‑6(1)(c)].

[3]             In order to meet the requirement of Rule 11‑6(1)(c), all actual instructions received by the expert should be appended to the expert report that is to be tendered into evidence.  It is not sufficient to satisfy Rule 11‑6(1)(c) to have the expert either to paraphrase the instructions received or to include some but not all of the instructions received.

[4]             The parties will be at liberty to file affidavits setting out the instructions that were provided to the experts who have provided reports which have now been tendered into evidence.
