Scottish Premier League chief executive Neil Doncaster has told Rangers not to expect any special treatment if they apply for re-entry to the top-flight as a newco.
Prospective new owner Charles Green - who met with Doncaster and Scottish Football Association counterpart Stewart Regan at Hampden on Thursday - is keen for the club to exit administration via a Company Voluntary Arrangement (CVA).
If a CVA is not possible, the consortium fronted by Green may be forced down a newco route instead.
Boss Ally McCoist has admitted in the past that dropping down to the Irn-Bru Third Division may be morally right but believes such a scenario would be to the detriment of the rest of the SPL.
Doncaster was quoted in several newspapers saying: "We will continue to deal with clubs equally under the rules.
"Our job is to apply those rules, without fear or favour to every single one of the 12 member clubs. That's what we will do.
"It's our job to explain that what we are doing is treating people equally. If everyone understands that, then what will be the reason to be aggrieved about the outcome?
"Every club will be treated exactly the same. I can't get into 'special cases'. Our job is to apply the rules fairly and evenly to every SPL club."
The SPL are also investigating the alleged use of 'double contracts' at Ibrox but Doncaster says no verdict is expected soon.
He added: "It will take some time and, ultimately, it's being done by our lawyers. How long will it take? How long has the HMRC case taken?
"These things take as long as they take."
Meanwhile, Green told representatives of fans' groups on Thursday night that investors have already committed £20million to the stricken club.
However, supporters are concerned by the former Sheffield United chief executive's unwillingness to name others involved in the consortium.
Rangers Supporters Trust chairman Mark Dingwall told the Daily Record: "We need clarity on who potentially are going to be owners of our football club and he was not able to give us names. He said the people involved want confidentiality at the moment.
"He told us that five or six have committed financially to the group and 20-odd are considering doing so but no names. He said the administrators have seen proof they have a bank account with £20million deposited.
"We will have to wait and see how it develops but the fact he could not be transparent about the identity of his group remains concerning."
Celtic manager Neil Lennon has spoken of his respect for opposite number McCoist following what has been a turbulent debut season for the Rangers manager.
Speaking in an interview with Real Radio to be broadcast on Monday, Lennon said: "It's just professional.
"Again, this is the downside of the Old Firm at times, it's difficult to socialise.
"But I've got a lot of respect for Ally as a man, he's had to deal with things that he shouldn't have had to deal with this year, he's dealt with them very, very well."
