This fit and proper person situation needs to be seriously looked at by the EFL.
While accepting the EFL are a flawed organisation, I do have some sympathy with them dealing with the 'fit and proper' ownership conundrum. I imagine a lot of financial documentation has to be taken at face value, particularly from abroad, with much of the information nigh on impossible to verify. They also have to tread very carefully, as I imagine labelling someone as not 'fit and proper' without cast iron evidence could end up in costly legal action. It is also the case that at most clubs, supporters are in favour of take overs and would be up in arms if they were denied by the governing body. The criticism of the EFL tends to come retrospectively when things eventually go wrong.
In terms of Wigan particularly, while I sympathise to a degree with their fans I don't see why they should not be docked a points penalty like others (including ourselves) have faced previously. By definition the fact they have gone into Administration means they have spent more than they can afford, gaining them an unfair competitive edge on their rivals. Would they have been a Championship club without that? Since Leicester pulled a fast one, everyone now knows there will be points penalty's for doing this, and for consistency purposes this needs to apply to Wigan like everyone else. At the end of the process Wigan fans will still have their club to support, but maybe at a more realistic level, with players paid more akin to their means.
