In the case of Ntiashagwa V Amodu (1 509) WNLR 273 the word “illiterate” has been defined to mean “a person who is unable to read and understanding and to express his thoughts by writing in the language used in the document made or prepared on his behalf.” This definition was endorsed by Kutigi JSC, later CJN (of blessed memory), in the case of His Highness V.A. Otitoju vs Governor of Ondo State & Ors (1994) SCNJ (pt.II)224 at 234.
ILLITERACY IS AN ISSUE OF FACT
It is necessary to recognize that the issue whether one is literate or illiterate is an issue of fact which cannot be presumed. It must be established by evidence.
