OTTAWA – Newly released court documents describe how a junior Conservative staffer in Guelph, Ont., charged with elections offences bragged about his allegedly fraudulent exploits to other young partisans.

A judge has partially lifted a publication ban that prevented the release of details on Elections Canada interviews with six Conservative workers.

All six suggest that Michael Sona boasted to them about his alleged involvement in a series of fraudulent automated phone calls during the local Conservative candidate’s 2011 Guelph election campaign.

The documents also reveal that three of those witnesses were brought to elections investigators by Arthur Hamilton, the Conservative party lawyer, who then sat in on interviews with all six of the witnesses.

Hamilton did not represent the witnesses, several of whom were not employed by the Conservative party, raising questions about his involvement.

The names of the six witnesses remain under a publication ban, with a decision to be announced Friday on whether that information can be released.
