(e) if the lease or licence has been granted in error, whether such error relates to the area or to the boundaries or to any other matter whatsoever; and
(f) where the lessee or licensee, before the expiration of the term of the lease or licence, surrenders the lease or licence in the manner prescribed.
(2) Any such revocation shall be without prejudice to any claim against the holder which may have become due to the Government of the Federation.
