Rangers chief executive Charles Green claims he could use sex discrimination laws to sue UEFA if they try to block the club's moves to join a cross-border league.
Green vowed to look into ways of taking Rangers out of Scottish football following the announcement of a new 12-18-18 league set-up - drawn up by the Scottish Premier League and Scottish Football League - that would keep the Light Blues in Scotland's basement tier, even if they win this season's Third Division title.
And the Ibrox chief told TalkSport: "As the structures stand now, there are not many options. People say you can't go into England because you are not allowed cross-borders (leagues). Well there is now a cross-border (league). You have a UEFA-sanctioned professional women's league in Belgium and Holland, so we have a precedent there."
He added: "If there was an opportunity to join a cross-border league and that was challenged by UEFA, I would go to Strasbourg and challenge the sexual equality."
Green also claimed that Rangers could apply to join the English Conference set-up before attempting to rise up the leagues, and he insisted he would do so with the blessing of the club's supporters.
"I could join the Conference and I would be in a higher league than I'm in. It doesn't matter to me (which league Rangers are in)," he added. "I can tell you this, if the only option is to go into England and start at the lowest level, I believe Rangers fans would support that.
"Nobody can question Rangers fans once they see the attendances. I got figures through yesterday and it's only Man United, Arsenal and Newcastle (that have) higher average attendances than Rangers."
Green also insisted that if Rangers were denied entry south of the border, Premiership side Swansea and npower Championship side Cardiff should then be booted out of England.
He said: "People say you are not allowed in the English league - well let's then kick Cardiff and Swansea out, because they are playing in a different country.
"People are saying Wales is fine but Scotland is not. We cannot have a situation where one of the Union is annexed by the football bodies but Wales can join. It's rubbish."
