The crucial question to be answered in this appeal is what is the effect of the non-registration of Exhibits -E’ and ‘F which are registrable instruments within the provisions of section 2 of the Land Instruments Registration Law. There is a long and impressive judicial authority for the proposition that the non-registration of a registrable instrument renders such instrument inadmissible as evidence in a litigation where such instrument is relied upon as evidence of title. – See Abdallah Jammal v. Said; & Fetuga 11 NLR. 86. Elkali & anor. v. Fawaz 6 WACA. 212 at p. 214. Coker v. Ogunye (1939) 15 NLR. 57; Ogunbambi v. Abowab (1951) 13 WACA. 222. Amankra v. Zankley (1963) 1 All NLR. 364. Section 15 of the Lands Instrument Registration Law provides simply as follows – “No instrument shall be pleaded or given in evidence in any Court as affecting any land unless the same shall have been registered. Provided that a memorandum given in respect of an equitable mortgage affecting land in Eastern Nigeria executed before the 1st day of July, 1944, and not registered under this Law may be pleaded and shall not be inadmissible in evidence by reason only of not being so registered.”
