In an interview with CBC News Network'sPower & Politics, Tom Flanagan, a professor at the University of Calgary and former adviser to Harper said Kenney's office "made a mistake" by filing a formal complaint against Mamann.
Although Mamann hasn't provided any evidence to support his claim, Flanagan told guest host Hannah Thibedeau "you can't start complaining every time somebody does that. So Jason [Kenney] has brought this on himself."
Mamann said he saw the complaint as an attempt by the minister to have a chilling effect not just on him but also on other lawyers.
The complaint was intended "to shut me up and people who think like me," Mamann said.
