While I can't comment on the particular case, I would say that these amendments are pretty discrete. They help address some of the particular challenges, but in very narrow circumstances.
I can give you one example. If someone has entered an invitation to apply and they've had a subsequent change of circumstance that would change their points—they've had a birthday and their age has changed—this would allow the immigration officer to allow that candidacy to continue. There is some narrow flexibility.
I'm not aware of the particular case in terms of the fee payment and the cost payment. It doesn't sound like that would be addressed, but I can't comment without knowing the case.
