8If the claimant is aggrieved by the failure of the local authority to inform him of their decision upon his claim within the time required by any direction of the Minister, or by the refusal of the authority to grant any compensation, or by the amount of compensation assessed, the claimant may, within three months after the failure, or after the date on which he receives notice of the decision of the authority, as the case may be, appeal to the Minister, and the Minister shall consider the case and determine whether any compensation, and if so what amount, ought to be granted to the claimant, and his determination shall be final.
