To answer your direct question, it was very evident, very early, that Leadnow was engaged. I believe it was an outside media source. It wasn't one of the political parties that identified this cheque coming up from a San Francisco organization, which Leadnow readily admitted it had taken into its coffers.
In terms of going forward, it's this simple: If you are serious about arresting the undue influence of third parties, you need a complete code of conduct that deals with both sides of the question. Yes, you want to stop the mischief-makers in the third party from foreign sources, but you also want to make sure that our regulators have the ability to challenge those who are receiving the money as the third party.
You need to put a sanction on the people who figure they can just ask for forgiveness later. That may be one way that some people think effective regulation occurs. In the electoral setting, the horse is very much out of the barn by the time any regulator can, if they choose, try to get to the bottom of something months or even years later.
Just so you know, our request for an investigation of Leadnow by the Conservative Party, as I understand it, remains an open investigation in the year 2018. The election was three years ago and that remains open. If you want to tell me that's an effective piece of regulation that keeps the third parties in exactly the position our Supreme Court has directed they should be kept, without pointing fingers at anybody, it's been an abject failure.
