Issue estoppel arises when the issue has been decided upon to finality by a Court of competent jurisdiction. In other words, once an issue has been raised and distinctively determined between the parties, neither party can be allowed to fight that issue all over again. The same issue cannot be raised by either party again in the same or subsequent proceedings except in special circumstances. See Adone & Ors v. Ikebudu & Ors (2001) LPELR 191 (SC) and Tukur v. Uba & Ors (2012) LPELR 9337 (SC). For issue estoppel to apply, the following conditions must be satisfied: (a) The same question was decided in both proceedings; (b) The decision which creates the estoppel must be final; and (c) The parties to the judicial decision or their privies to the proceedings in which the estoppel is raised. To determine whether the above three elements exist (they must co exist), the Court will closely examine the reasons for the judgment and other relevant facts that were actually in issue in the proceeding. See Oyekola & Ors v. Amodu (2017) LPELR-42391 (CA); OSPM Ltd v. Nibel Co. Nig. Ltd (2017) 3 NWLR (pt.1552) 207 at 234 and Dasuki (Rtd) v. F.R.N. (2018) LPELR-43969 (CA).
