The council is accusing Ms Gorman of committing 34 offences under planning law. It has recommended court action on 17 of these breaches, each of which carries a maximum fine of £20,000 or six months in prison.
Ms Gorman is alleged to have knocked down walls and added French windows to the 15th century farmhouse.
A spokesman for the council denied its action was politically motivated. 'The council carries out regular checks of listed buildings,' he said.
Ms Gorman said she intended to challenge the allegations and the way the council released a planning committee agenda, detailing the alleged abuses, to the press.
'The fact that the agenda was given to the press before I had sight of it, and while I was abroad, appears to me to constitute trial by media,' she said.
