At para. 2.19: In the case of Dr. Arthur Agwuncha Nwankwo and Ors V. Alhaji Umaru Yar’Adua and Ors. (2010) LPELR-2109(SC), the apex Court held as follows on the interpretation to be accorded the word ‘shall’ in a statute, “The word shall when used in a statutory provision imports that a thing must be done. It is a form of command or mandate. It is not permissive, it is mandatory. The word shall in its ordinary meaning is a word of command which is normally given a compulsory meaning as it is intended to denote obligation. Bamaiyi V. A.G.
