8(1)If the deposited plans or the book of reference to those plans are inaccurate in their description of any land, or in their statement or description of the ownership or occupation of any land, the Secretary of State, after giving not less than ten days' notice to the owner and occupier of the land in question, may apply to two justices having jurisdiction in the place where the land is situated for the correction of the plans or book of reference.
(2)If on such an application it appears to the justices that the misstatement or wrong description arose from mistake or inadvertence, the justices shall certify accordingly and shall in their certificate state in what respect a matter is misstated or wrongly described.
(3)The certificate shall be deposited in the office of the Clerk of the Parliaments and a copy of it in the Private Bill Office of the House of Commons and at the principal offices of Avon County Council, Gwent County Council, Bristol City Council, Northavon District Council and Monmouth Borough Council; and the deposited plans or the book of reference shall be deemed to be corrected according to the certificate and it shall be lawful for the Secretary of State, in accordance with the certificate, to proceed under this Act as if the deposited plans or the book of reference had always been in the corrected form.
(4)A person with whom a copy of the certificate is deposited under this paragraph shall keep it with the documents to which it relates.
(5)In this paragraph “book of reference” means the book deposited in November 1990 in connection with the Severn Bridges Bill in the office of the Clerk of the Parliaments and the Private Bill Office of the House of Commons.
