The land in dispute being developed land before the Land Use Act came into force, who ever had it vested in him then was deemed to have continued to hold the land after the commencement of the Act as if he was the holder of a statutory right of occupancy issued by the Governor under S.5 of the Act. It then follows that no other person can be granted a right of occupancy unless S. 28 of the Act is complied with. Any right of occupancy otherwise purportedly granted is contrary to the provisions of the Act and will be of no validity. See Teniola v. Olohunkun (1999) 5 NWLR (Pt.602) 280. It will be set aside by the court in an appropriate case, or be discountenanced when relied on as against a subsisting holder or deemed holder of a right of occupancy.
