It helps to sort out matters of priority of entitlement as it is settled law that priority as regards registrable instruments is determined by date of registration of the instrument under this law, and not by the date the instrument was drawn or made. In Amankra V. Zankley (1963) 1 All NLR 304 where the same Vendor conveyed title to the disputed land to both parties, the Defdant who had the land conveyed to him by a registrable instrument on 16/5/57 but registered the instrument on 17/03/1960 lost out to the Plaintiff who got the land conveyed to him on 29/08/1957 and had it registered on 16/09/1957. The ordinary sound legal argument that since the Vendor divested himself of the title to the land in favour of the Defendant in May of 1957 he had nothing again to convey to the Plaintiff in AUGUST of 1957 (based on principle of nemo dat quod non habet) does not hold legal waters in this instance. The rationale could be said to be that by failing or refusing or neglecting to have the instrument registered earlier, as the Defendant had all the opportunity to have done, he had waived his right of priority, as his failure to so register the instrument might have acted to deceive the Plaintiff, who after conducting a search of the Register of Lands and did not find it in any other person’s name was led to believe that the land was free, unencumbered and still owned by the vendor. This principle of priority of interests according to the date of registration under the Land Instrument Registration Laws has been well affirmed by the Supreme Court in a long list of cases, including the ones of Olumide V. Ajayi (1997) 8 NWKLR (Pt. 517) 433 and Tewogbade V. Obadina (1994) 4 NWLR (Pt. 338) 326.
