The Duties of Expert Witnesses

Wendy Reynolds from Slaw recently posted on a proposed regulatory change to the Rules of Civil Procedure with respect to the duties of expert witnesses. Coming into force in two years, the December 27, 2008 Ontario Gazette lists several amendments to the Rules of Civil Procedure including:

RULE 4.1 DUTY OF EXPERT

 

Duty of Expert


4.1.01 
(1)
  It is the duty of every expert engaged by or on behalf of a party to provide evidence in relation to a proceeding under these rules,

(a) to provide opinion evidence that is fair, objective and non-partisan;

(b) to provide opinion evidence that is related only to matters that are within the expert’s area of expertise; and

(c) to provide such additional assistance as the court may reasonably require to determine a matter in issue.

Duty Prevails

(2) The duty in subrule (1) prevails over any obligation owed by the expert to the party by whom or on whose behalf he or she is engaged.  

 

It will be interesting to see what impact, if any, this amendment will have on the duties of expert witnesses. Case law already suggests expert witnesses are already required to report in an independent manner and cannot been seen as an advocating for the party that retains them. The strength of an expert witness comes from their objective evidence and the evidence of an expert witness will be rejected if they are bias.

 

Does this proposed Rule merely confirm the well established principles of expert evidence as it has developed in case law or does it go beyond establishing the independence of an expert witness? Are we moving towards the use of joint experts to assist the Court? We have a few years to find out.

Getting the Right Evidence

Over the next week, I will blog on a variety of topics within the estate and and trust world. I will canvas notable case law as well as draw on my recent experience. My first topic deals with evidence.

It is crucial when litigating to amass the right evidence. A great deal of thought usually goes into deciding whether to litigate, but once that decision has been made, the right evidence has to be put forward in order to win or to facilitate a favourable settlement. Much of what litigators now do is by way of application so affidavit evidence is key. The beauty of affidavit evidence is that it allows the lawyer time to draft or finesse the evidence - not change it, but just present it in its most persuasive format.

When dealing with a will challenge and capacity, the notes of the solicitor who drew up the will are obviously critical, as is any medical evidence particularly from a family doctor. In a guardianship fight, medical evidence is again key, but so is evidence from family or friends. However, when deciding what evidence to submit, a careful litigator will take the time to decide what evidence is required over and above the usual. In other words, what avenues are worth exploring that may reveal the unexpected. Is there some person who may be able to add fresh evidence that will make the difference and carry the day?

In a recent guardianship case that I was involved with, the evidence of two neighbours turned out to be critical. The neighbours were able to comment on the slow deterioration of the incapable. As family members had applied to the court to be appointed guardians, the neighbour were also able to comment on whether the family members visited and how often. The neighbours, who still kept in touch with the incapable, were also able speak to the wishes of the incapable when it came to who should look after the incapable. A caregiver at a nursing home was also in a position to comment on the mental state of the incapable and, in fact, assisted a doctor who was retained to prepare a retrospective assessment. What the neighbours and the caregiver brought to the table was the fact that their evidence was credible and independent. In other words, they had no particular stake, one way or the other, in the outcome of the litigation. They were simply interested in doing what was best for the incapable. When it comes to evidence from outside or third parties, their evidence will likely be believed because it is seen as untainted. As a result, every effort should be made to get evidence from outside or third parties and from sources that may be out of the ordinary.
