Now, for a judgment to constitute issue estoppel the following conditions must be satisfied: – 1. the same question must be for decision in both proceedings (i.e. the same question for decision in the current suit must have been decided in the previous suit); 2. the decision relied upon to support the plea of issue estoppel must be final; 3. the parties or their privies must be the same. The three elements must be present and co-exist for a plea of estoppel per rem judicata to apply. See Ito v. Ekpe & Ors (2000) 3 NWLR (pt. 650) 678; Oshoboja v. Amida & Ors (2009) LPELR-2803 (SC) and Oleksandr & Ors v. Lonestar Drilling Co. Ltd & Anor (2015) LPELR – 24614 (SC).
