No, there is some confusion around the recusals and the conflict of interest screens. Basically, the screens are put in place so that information doesn't get to the person who has the screen. In other words, a decision-making situation doesn't penetrate the screen. Someone is designated to enforce the screen. There is no recusal involved because no information has gone through. If something penetrates the screen by accident, then they would have to recuse.
I have an action taken against me in the Federal Court for misusing the act by making this system of conflict of interest screens, but the whole purpose of those screens is to prevent a conflict of interest happening. It doesn't negate the recusal system at all, if necessary. Sometimes it may be a surprise that something comes up. You wouldn't have foreseen it, and then you'd have a recusal.
