It's hard for me to say, based on my role and his role as employee of the department.
It sounds like he was still involved, at least on paper. I think the more important piece to me is that Mr. Yeo did not see the conflicts, in fact or in appearance, with his employment role and he failed to disclose those conflicts to National Defence as his employer.
Whether he believes he was in conflict or not, clearly there's a conflict in appearance. He did not see that and he did not take appropriate steps.
