16.2. Entitlement to any allowance granted by the Board which has not been paid to the person entitled to it for a reason attributable to him, including, but not limited to, failure to report his new address or to cash a cheque he received, is prescribed by five years from the last day of the month in which the payment should have been made.
However, where the allowance cheque was issued after the end of the month in which it should have been issued, the prescription period of five years runs from the date of the notice of the decision confirming entitlement to the allowance.
