I think it's universally accepted that money can buy you anything, even people's silence.Well by that reckoning, judges are pointless and don't make any decisions.
Anybody can apply for anything they want. Applying for something is irrelevant.
The point, is that a judge decided that in the eyes of the law this would prejudice the case. Probably with extremely good reason.
If he committed those criminal offences he should NOT have the right, by way of his immense wealth to buy people's silence. It is for the Courts to decide his guilt or innocence, not for a panel of judges to influencee the likelihood of him facing the charges.
