It is settled law that the question of jurisdiction is fundamental and crucial to adjudication and that the very fact of its absence automatically results in a nullity of proceedings no matter how well conducted. It is for the above reasons that it is further settled law that when raised in a proceeding, it must be specifically dealt with and resolved. See Onyema vs. Oputa (1987) 3 NWLR (pt. 60) 259; A.G of the Federation vs. Sode (1990)1 NWLR (pt. 128) 580; Ishola vs Ajiboye (1994) 6 NWLR (pt. 352) 506; Madukolu vs Nkemdilim (1962) 2 SCNLR 341.” Per ONNOGHEN, C.J.N. in RAHMAN BROTHERS LTD V.
