In legal proceedings, sometimes it is necessary for the judge to be educated on advanced scientific issues. In such cases, expert evidence is sought.
Although courts have always decided whether an expert91裸聊视频檚 evidence is admissible, Canadian courts are increasingly scrutinizing proposed experts for potential biases.
A paper entitled 91裸聊视频淓xpert Witnesses and Bias: Case Examinations91裸聊视频�, by a Canadian lawyer named Ms. Lisa Wannamaker, describes the origins of the increased scrutiny now given to expert testimony.
The increased scrutiny began around the time of the 2008 Goudge Inquiry in Ontario. This report is a fascinating read.
Justice Goudge reviewed the work of Dr. Charles Smith, a forensic pathologist regarded as a leading expert in the field of 91裸聊视频減ediatric pathology.91裸聊视频� In numerous cases involving children91裸聊视频檚 deaths, Dr. Smith testified that children were murdered or otherwise seriously injured, even though the evidence simply did not support that conclusion.
Interestingly, pediatric pathology was not even a true field of expertise.
The inquiry examined 45 cases involving Dr. Smith. It found many problems.
A number of cases in which his testimony was originally accepted were later reversed on appeal. Many were acknowledged as wrongful convictions.
Individuals and entire families were devastatingly impacted by irresponsible expert testimony.
The Goudge report made numerous recommendations regarding expert evidence. It discussed how experts should approach their role, how lawyers should deal with experts, and how judges can best control expert evidence to ensure unreliable evidence is not admitted.
Hot on the heels of the Goudge report, Justice Paciocco, a law professor who is now a judge, wrote a paper, Unplugging Jukebox Testimony in an Adversarial System: Strategies for Changing the Tune on Partial Experts, which is frequently cited in courts across Canada.
Justice Paciocco identified various types of biases that experts may harbour. Some may be obvious. Some may not.
A major area of concern is experts who are not independent. This concern may arise if the expert has a relationship with the party in the proceeding that extends beyond the particular case. Examples include 91裸聊视频渙ngoing employment,91裸聊视频� a 91裸聊视频減ersonal relationship91裸聊视频� or a 91裸聊视频渟ignificant history of retainers.91裸聊视频�
Such relationships raise a red flag on the expert91裸聊视频檚 independence.
Concerns that an expert is not impartial can also arise. For example, an expert may naturally want to 91裸聊视频渄o something serviceable for those who employ you and adequately remunerate you.91裸聊视频� One example is an expert who focuses only on information or results that support a certain outcome, while ignoring contrary information.
Experts may also lack impartiality if the expert feels that the party on whose behalf he or she is testifying has a morally superior case. This may result in the expert finding information to support that belief.
As was stated by the British Columbia Court of Appeal in J.P. v. British Columbia (Children and Family Development),
91裸聊视频淓xpert opinion evidence must also be fair, objective and non-partisan to be admissible91裸聊视频f an expert is not properly qualified and is not neutral, his or her opinion has the potential to 91裸聊视频渟wallow whole the fact-finding function of the court.91裸聊视频�
91裸聊视频淥pinion evidence that fails to meet these requirements is prejudicial to each party91裸聊视频檚 right to a fair determination of the issues, lacks probative value and is therefore irrelevant, unnecessary and unhelpful.91裸聊视频�
So, if you are involved in a proceeding of any type, and you feel an 91裸聊视频渆xpert91裸聊视频� witness is not sufficiently independent or impartial, be sure to raise it with your lawyer. With much work by the lawyer, it is possible that a court may agree with you.
If you are a self-represented litigant, and this an issue in your case, you may already be aware that there is a huge body of law around expert evidence. The law in this area can be very technical and highly legal. Sadly, this is one area in which retaining counsel may become necessary.
