The Crown prosecuter at the trial of David Livingston and Laura Miller has asked the judge to acquit the two accused on one of three charges they face. Tom Lemon said there was no reasonable prospect of conviction on the breach of trust count against the two former aides to Dalton McGuinty when he was premier. But Livingston and Miller still face charges of mischief and unlawful use of a computer. The prosecution alleges they illegally destroyed documents related to the Liberal government’s decision to scrap two gas plants hours before the 2011 general election.
