A hearing took place this morning but senior judges adjourned her case so that expert medical evidence could be obtained. Her case will continue tomorrow.
Presiding judge, Lord Justice Irwin, said that her case has an “extraordinary history” and should be resolved as soon as possible.
“We cannot go on middling this case, there has to be a decisive conclusion,” he told the Court of Appeal.
Mr Justice William Davis said that the case will examine whether a “natural succession of events” which could cause hypoglycemia – dangerously low blood sugar levels – “and therefore death” was responsible.
However Mr James Curtis, prosecuting, told the court that Mr McMcCarthy’s death “was not caused by some internal sudden lightning strike with the body turning in on itself” and added that evidence suggesting that he died of natural causes is “not fresh” and has “been covered various ways, a number of times before”.
Just a few days after Mr McCarthy’s motorcycle accident, he lapsed into a coma and died in Hinchingbrooke Hospital in Huntingdon on February 9.
This is not the first time that Winzar has tried to overturn her conviction. A previous challenge was overturned by the Court of Appeal in December 2002. She applied to the CCRC in June 2005.
