I'm not sure that you are correct. There is no such thing as "demotion to the Third is punishment for liquidation". It simply does not exist. The rationale behind Rangers going into the Third Division was that they were a new business entity and thus a new club. As a new club, Rangers would have to start from the bottom. But there is no pyramid system in Scottish football, and there were plenty of junior clubs eager to take up the vacant spot in the league - notably Spartans and Forres Mechanics. Rangers did not start from scratch: they were parachuted into the Third division. Whilst Rangers were no doubt glad not to have to play in the juniors, it does undermine the notion that a new club has to start from the bottom. If it was acceptable to parachute new co Rangers into the Third, why was it not acceptable to parachute them into the Premier, or the First?
But, the stated reason for Rangers going into the Third is that they were a new club - even if financial concerns persuaded the league that Rangers would bring more money to the league than, say, Spartans. But new co Rangers have also been made liable for debts owed by the old co to other football clubs - transfer money to Hearts, gate money to Dundee United, legal bill handed out by the SPL for investigating the dual contracts, etc. So Rangers are a new co for the purposes of league position, but are also the old co whenever someone hits them up for money.
