The Islands’ council has been threatened with legal action after failing to comply with new disability discrimination laws.
The Disability Rights Commission has issued the authority with a compliance notice because it has not written an equality scheme.
The scheme, which outlines how the council promotes disability equality, was due to be completed by December 4.
Commission spokeswoman Marie Rye said Scilly was one of nine out of 1,700 public bodies which had not registered their report.
She said both the commission and the government office for disabilities had written requesting the document but had not received it.
The council denied it had received a letter from the commission prior to this week.
It now has 28 days to comply with the notice to prevent being taken to court.
