In my ignorance I would say this. The Chairman of the DFC Board is a lawyer by profession and that is to be welcomed. However, if Brabco decide they are off via a sale of their shareholding (unlikely), or by just putting a padlock on the front door, I don't consider that in the UK of 2019 there aren't ways for a clever legal advocate for Brabco to enable the latter, Companies Act or not.
From where I'm sitting the DFC Board may hold the moral high ground but Brabco hold most of the meaningful cards, and whilst the Golden Share was designed to protect the club I can't imagine where the money would come from to prove its legal worth.
