22. The Minister may, at the request of the Bureau, cancel the right of a natural person or group operation to whom or which a grant was made to receive the unpaid instalments under the grant
(1) if the person or group operation refuses to receive payment of the grant;
(2) in case of non-execution of the loan in respect of which the grant was made;
(3) if the deed evidencing the loan or the deed under which the loan is assumed is cancelled or revoked before any payment of the grant is made.
Where a cancellation contemplated in the first paragraph occurs before any payment of the grant is made, the loan is, for the purposes of this Act, deemed never to have been granted.
