The former Commissioner of Finance for the city taking the stand in the defamation lawsuit between the city's pension board and former city councillor John Ferguson.
Daryl Wilson also served as the treasurer on the pension board.
When questioned by pension board lawyer Barry Morrison, he said he had no knowledge of any illegal activity on the board or anyone abusing long-term or permanent disability benefits.
But under cross-examination by the defense, Morrison acknowledged emails from an actuary that stated the city had an abnormally high number of people on permanent disability and the legal definition the city is using may need to be examined.
The trial resumes Wednesday afternoon and is expected to last 6 weeks.
