There is a separate case, still pending, concerning Marius's 100k signing on fee, and something about (alleged) unlawful deductions from his salary.
Yes, the Swiss case was about Marius trying to claim a share of the transfer fee we received, the Inverness case is to do with his original signing on fee which was payable in 2 instalments. He wasn't paid the 2nd one because he had gone by the time it fell due for payment.
Whether or not he is entitled to it would depend on what his contract says about that scenario, but it may well be silent on the subject. I wouldn't be surprised if Marius wins this one, simply because it is an employment law case and employees tend to get the benefit of any doubt (even when they are in the wrong). He'll have to get time off work to come over for the case though.
