I know this refers to previous rules and there are new ones in place now but some quotes from the actual judgement that I'm just reading through now:
"We went on to conclude that the justification advanced by the PL for the exclusion of shareholder loans “is a justification that is at odds with the whole rationale of PSR, and namely to ensure that a club operates in a sustainable way and does not rely on shareholder support. It is also at odds with the proposal to tighten up the PSR to prevent avoidance of those rules.” (ibid. para. 250.) We found that “a limitation in the scope of the APT Rules so as to cover only certain APTs is discriminatory” and that such a limitation is “an obvious distortion of competition as it permits one form of subsidy, namely a noncommercial loan, but not another, a non-commercial sponsorship agreement. Both are equally injurious to the objective of the PSR.”
"a change in legal effect, namely from a position of zero scrutiny to full scrutiny. We consider that this is a very significant expansion in the legal effect of the APT and Amended APT Rules. Moreover, since the different treatment of shareholder loans as compared with other APTs is an obvious distortion of competition as it permits one form of subsidy but not another"
And the conclusion is a nice thing to look forward to:
"69. However, there remains for decision (in the fresh arbitration commenced on 20 January 2025) whether the November 2024 Amended APT Rules are valid and effective."
