The government already rejects applications by ghost consultants if that IMM 5476 form has an individual who's not registered with ICCRC or is not a member of a provincial law society. The government won't process that, so that's already there. The reason they're ghost consultants is that their names don't show up anywhere on the forms.
What I would suggest is a more robust reconsideration regime. We have so many cases where applications are simply refused, where someone is prejudiced by ghost consultants or incompetent advice. I think there should be a mechanism to review an application. I don't think the default should be to simply reject an application. There should be a more thorough, robust reconsideration or review mechanism for certain applications.
