A football agent from Belgium is challenging UEFA's financial fair play rules at the European Commission on the basis that it will lead to a drop in agents' income.
Daniel Striani is being represented by Jean-Louis Dupont, the lawyer who in 1995 secured the Bosman ruling that allowed players to move on a free transfer at the end of their contract.
Dupont believes the 'break-even rule', which prohibits clubs in European competition spending more than their income, "infringes EU fundamental freedoms" such as free movement of capital, of workers (players) and of services (agents).
"Consequently, such restriction of competition and violation of EU fundamental freedoms cannot be justified by the objectives put forward by UEFA," said a statement from Dupont.
He is claiming that overspending should be allowed so long as it is fully guaranteed, such as by bank guarantees.
"In short, the current prohibition... is in practice illegal because the rule is not proportionate, since it can be replaced by another measure, equally efficient but less damaging as far as EU freedoms are concerned," says the statement.
UEFA believes it has already tested the break-even rule's legality with the EU.
"UEFA believes that financial fair play is fully in line with EU law and is confident that the European Commission will reject this complaint," it said in a statement.
"The rules encourage clubs to 'live within their own means,' which is a sound economic principle aiming to guarantee the long-term sustainability and viability of European football."
Clark, 21, has enjoyed a scintillating season, scoring 41 goals this season which not only helped his side lift the Ransdens Cup, but also landed him the coveted PFA Scotland Second Division Player of the Year Award.
Speaking about the interest from Rangers, Clark stated: "Ally McCoist has said there is a wee bit of interest and has spoken to my dad and my agent.
"I've not spoken to him yet but we'll see what happens over the next couple of weeks and, hopefully, something can get done.
"A move to Rangers would be a major step up for the highly-rated youngster, one which he says, he can't turn down.
"Rangers are the best club in Scotland in my eyes so I'd find it hard to say no to them.
"There are a few clubs down south interested so I need to weigh up my options but if Rangers say they want to sign you, you can't get much better than that."
Talking about his incredible form this season, Clark says its all down to confidence and the quality of the squad.
"There are good players in the team and they have to take plaudits for it as well.
"The manager and my dad have done well. They brought good experienced players in, like Derek Young and Derek Lyle. That helped a lot.
There is little doubt Clark shares a special relationship with his Dad, Sandy, after revealing how proud he was at his achievements. He added: "Earlier in the year, he was winding me up that he scored 29 or something in a season but I said I'd beat that no bother. It put me under pressure but I did it and he's delighted for me."
