The spokesperson for the general secretariat of the council, Jakob Thomsen, said: "Given the arguments raised by Ireland and after having examined the content of the requested documents, the general secretariat came to the conclusion that their release would undermine the protection of the public interest as regards the financial, monetary or economic policy of the union."
A spokesperson for the Department of the Taoiseach said it is the long-standing position of the Government not to release documents relating to international relations, even where they impact on domestic policy.
However, the spokes-person added that the Government is committed to transparency.
"It of course remains the position of the Irish Government to provide transparency to the public," the spokesperson said.
"This was reflected in the unprecedented level of detail provided to the public in the information campaign around the stability treaty referendum."
Mr Thomsen said the sensitive political nature of the fiscal compact and the current climate in Europe were all taken into account when assessing whether to release the documents.
"In view of the particular political sensitivity of the matters dealt with by the fiscal compact treaty, where the ratification process in member states is still ongoing, public access to documents submitted in the context of the negotiations demands particular caution," he said.
