SALAMI AFOLABI V. GOVERNOR OF OSUN STATE (2003) 13 NWLR (Pt.386) 119 at 129 – 130 the Supreme Court emphasized thus: “It is settled law that to sustain in a plea of res judicata, the party pleading it must satisfy the following conditionalities, to wit – i. That parties (or their privies as they may be) are the same in the present case as in previous case; ii. that the issue and subject matter are the same in the previous suit as in present suit; iii. that the adjudication in the previous case must have been given by a court of competent jurisdiction; and iv. that the previous decision must have finally decided the issues between the parties”.
WHERE AN ISSUE OR FACT HAS BEEN DETERMINED IN A FINAL MANNER, IT CONSTITUTES ESTOPPEL PER JUDGEMENT
The law is settled that where an issue of fact affecting the status of a person or a thing has been determined in a final manner as a substantive part of a judgment of a court having jurisdiction to determine that status, such determination will constitute estoppel by judgment to any subsequent proceedings between any parties whatsoever.
