81.7. Every sale or alienation made in contravention of sections 81.5 and 81.6 entails relative nullity.
At the expiry of the delay provided in section 81.6, the land offered for sale in a designated territory may be alienated if the Minister has not notified his intention to exercise the right of pre-emption contemplated in the said section. The alienation must however be notified in writing to the Minister within fifteen days after it is effected.
