Notable Trial Decisions
Godknows Itamunoala, et al v. Karen L. Peirce, et al
The trial took place before The Honourable Mr. Justice Jennings over the period of two weeks and one day in December 2004. The Plaintiffs succeeded in establishing negligence against four Defendant Doctors.
The Plaintiff, Mr. Godknows Itamunoala, alleged that the Defendant Doctors failed to diagnose an underlying brain aneurysm. As a consequence of that failure, Mr. Itamunoala was required to seek emergency medical attention during a visit to the United States. Mr. Itamunoala, an Ontario resident, was put to a significant expense for the excellent care that the received from the U.S. hospital and its medical personnel, for which he did not receive reimbursement through the Ontario Hospital Insurance Plan (“OHIP”).
Within the endorsement of The Honourable Mr. Justice Jennings, His Honour stated:
The plaintiff’s case was commendably prepared and expeditiously and competently presented.
Medical malpractice cases are inherently complex and risky. They require a level of experience and skill, which counsel clearly met in this case.
Alfred Newman, et al v. William G. Swales
The trial took place before The Honourable Madam Justice J. Lack over the period of seven days in October 2001.
The Plaintiffs alleged that Dr. Swales’ management of Mrs. Newman on May 7, 1993, and afterwards failed to meet the standard of care reasonably expected of a general practitioner in a small Ontario town at the time. He failed to consider colon cancer or a precursor to colon cancer as a potential explanation for Mrs. Newman’s May 7, 1993 symptoms.
The Plaintiffs succeeded in establishing negligence against Dr. Swales. Damages were assessed and awarded.
On July 8, 1998, Elwin Taylor died in the Emergency Department of the Peterborough Civic Hospital as a result of a heart attack. He was just short of reaching 58 years of age. A post-mortem examination revealed that Mr. Taylor had severe coronary artery disease (CAD).
The trial took place before The Honourable Mr. Justice H. Spiegel over the period of three weeks in February and March 2006. The Plaintiffs succeeded in establishing negligence against the Defendant Doctor.
Within the endorsement of The Honourable Mr. Justice H. Spiegel, His Honour stated:
… the evidence regarding life expectancy was very complex and required considerable skill to properly present.
While it is true that Mr. Mandel had just achieved 10 years seniority at the bar at the commencement of trial, he conducted the trial with a degree of skill and expertise which far exceeded his level of seniority.
On November 24, 1989, 17-year-old Brenda Rene Murray was driving to school in her mother’s car. The road was snow covered with slushy and icy sections. Brenda lost control of her car, slid into the oncoming lane, and ran head-on into a pickup truck. Tragically, she was rendered quadriplegic.
A claim was brought against the Ministry of Transportation (“MTO”) for its failure to appropriately sand and salt the roadway.
Mr. Justice Jenkins found that the MTO was 70% at fault for the crash and the defendant appealed.
The Court of Appeal upheld the trial judge’s ruling and Brenda was awarded significant damages.
Mr. Mandel represented Brenda and her family both at trial and on Appeal.
