I think the case for Mandatory Reporting has been well made by so many representatives to the Inquiry, that it is bound to call for it in its Report, which they "hope" will be published in the Summer of 2021. We then have to wait and see if the Government can be arsed to put their recommendations in to Law.
I hope it is, along with instituting a Government run Body that audits and oversees all these religious groups and makes sure they are doing things properly. But it is a waiting game, things move slowly in this sort of area.
