If we remain focused on a whistle-blower-centred model that says, if that person has reasonable belief in the truth of what he or she is coming forward with.... They can be mistaken, as we all make mistakes and we can all be wrong, but if they have reasonable belief in the truth of what they're coming forward with, to me that settles it. I think that takes us away from the concept of intention and motivation.
For example, if someone blows the whistle on me, they may hate me and want me to be fired or die a painful death, or whatever. That has nothing to do with the fact that, if they come forward with facts about me misspending or abusing public funds, the motivation that they want to harm me is irrelevant. The only thing that is relevant is whether I abused those funds. If they have reasonable belief that I did, then I think we simplify matters by pushing motivation completely away.
An earlier version of our legislation actually had the ability of the commissioner to reject something if it was frivolous and vexatious. Parliament then replaced that with the good faith requirement. I think the next step is to get rid of the good faith requirement completely and start with the presumption that people are coming forward with reasonable belief.
If there's evidence to prove that someone did not have reasonable belief in what they came forward with, it would no longer be a protected disclosure. So I think it works itself out.
