St Mirren chairman Stewart Gilmour has hit out at Rangers for taking their fight against a transfer ban to court.
Lord Glennie ruled on Tuesday that a 12-month transfer embargo imposed on Rangers was unlawful as the punishment was not contained in the Scottish Football Association rules.
Gilmour, speaking at Hampden after a Scottish Premier League meeting on financial fair play issues, said: "The law is an ass. I think that sums it up.
"What's a court getting involved in football for? The decision had been made.
"Are we going to take every single sending-off to court? Is that what we are going to end up with? Sport should stay within sport."
Lord Glennie's decision overturned an SFA appeal tribunal, which was chaired by his fellow Court of Session judge Lord Carloway.
The judge proposed the matter be sent back to the SFA appeal stage, although the SFA had 21 days to appeal against the court decision.
Rangers could now face more extreme sanctions as the explicit punishments stated in the SFA's rule 66 are a maximum £100,000 fine, suspension or expulsion from participation in the game, ejection from the Scottish Cup or termination of membership.
Rangers, who owe the tax authorities more than £21million, were fined £100,000 for bringing the game into disrepute over their non-payment and an SFA appeal panel might now have the task of deciding which if any of the additional punishments Rangers face.
FIFA have also urged the SFA to take "direct action" against Rangers for taking the matter to court, which is expressly prohibited in both associations' rules.
