Guilty verdict in gas plants trial

A former top political aide in Ontario has been found guilty of destroying documents related to a controversial provincial government decision.

David Livingston, who was chief of staff for ex-Liberal premier Dalton McGuinty, was charged with attempted mischief and illegal use of a computer.

The destroyed documents were related to the Liberal government's costly decision to cancel two gas plants before a provincial election.

Judge Timothy Lipson says Livingston was a sophisticated individual who knew exactly what he was doing.

Livingston's deputy, Laura Miller, was also charged in the case and was found not guilty.
