I think the clubs and EFL / panel have been in 'talks' for the past week. Middlesbrough's sole action is to make the complaint, the censure comes from the panel. Let's assume that Saints will say that the 'spy' is a young kid not reporting directly to the coaching team or Board. If the situation can be resolved via internal disciplinary action and a fine of circa £500k (most likely), Saints will pay it to get rid off the problem. Points deduction plus a fine may stick in the craw but that call is on the Board in terms of appealing or moving on. If the panel goes further (which would surprise me) and am certain Saints will litigate as per the previous post. In large scale commercial litigation it's rather like poker in that the person with the deepest pockets usually wins, and that is Solak. To paraphrase the great jurist William Wonka, Gibson 'get's nothing!'*
*and if he does I very much doubt we will hear about it.
