Campaigners have been told a legal action will be resisted
Campaigners are considering legal action to allow Cornwall to be represented independently at the Commonwealth Games.
Kernow Trust, formerly the Cornwall Commonwealth Games Association, had an application refused in 2004.
It is now considering submitting a judicial review against the Commonwealth Games Federation.
Games organisers called it a "frivolous" act and said they would oppose any legal action.
Campaigners are hoping that Cornwall can be represented at the Games in Glasgow in 2014.
They cite a precedent as the summer Olympics of 1908 in which Cornwall competed in rugby.
Campaigner Graham Hart told BBC News: "Cornwall is a duchy, not part of England and we have every right to be there.
"England is no more a part of Cornwall than Cornwall is a part of England.
"England goes with the English counties to the games. We should go as a country."
Michael Hooper, chief executive of the Commonwealth Games Federation, said: "We have made it very clear that if proceedings start we will resist it.
"This is a frivolous act. I am not trying to undermine Cornish identity, but it is an English county as defined by the British government.
"His argument is with the British government.
"He can contest it in any form he likes."
He added: "If Cornwall becomes independent then an application can be made, but at the moment it is a county."
