TORONTO – The Toronto coroner overseeing a probe of the prison death of troubled Moncton teen Ashley Smith has rejected a motion to narrow the scope of the inquest.

Dr. John Carlisle says he will provide reasons for his decision at a later date.

Correctional Services and several doctors had argued the inquest should focus on Smith’s last week before her choking death in 2007 in a cell in Kitchener, Ont.

Her family argued the scope should be much broader, and fought successfully to have disturbing surveillance videos screened.

After that happened last month, Prime Minister Stephen Harper called Corrections treatment of Smith unacceptable.

He also ordered prison authorities to co-operate with the inquest.

As a sign of the new-found co-operation, four out-of-province doctors who had been fighting against summonses to testify agreed to give evidence voluntarily.

The inquest today also heard demands for Corrections to produce a full list of all relevant videos in its possession and turn over any it hadn’t already done so.
