The short answer is, the working group couldn't come to a consensus because they are actually different arguments. The argument for consolidating under the Conflict of Interest Act and the Conflict of Interest and Ethics Commissioner is that she and that statute are responsible for most post-employment restrictions. The argument for consolidating under the Lobbying Act and the jurisdictional lobbying commissioner is that the act and she and her office have specialized expertise in determining what lobbying is.
In addition, the group of designated public office holders is not the same as the group reporting public office holders. It's only the lobbying commissioner, her staff, and the act that deal with members of Parliament as designated public office holders. Mary Dawson, the Conflict of Interest and Ethics Commissioner, doesn't deal with MPs as reporting public office holders under the Conflict of Interest Act. So there are arguments for consolidation under both, and that's why we didn't settle on one or the other.
