Key legal issues
#Whether the court was functus officio and could re-open its own final judgment
The court was functus officio; it could not re-open the case to allow new evidence to fill gaps in the judgment
The suit was heard and determined by judgment delivered on 28th May, 2026. That judgment had not been varied or set aside by any competent court and no appeal had been lodged, so it remained binding on the parties and the court. Relying on Court of Appeal authority on finality and public policy, the court held that it had pronounced final judgment, was functus officio, and could not re-open the case to admit fresh evidence or arrive at a different decision.

the principle of functus oficio is grounded on public policy which favours finality of proceedings
In the end, this Court finds that the application dated 20th July, 2026 is bereft of merits. It is hereby dismissed with costs to the defendant.
Issues in the judgment
#Judgment repeatedly spells the doctrine 'functus oficio' instead of 'functus officio'
Internal date inconsistency: paragraph 5 refers to 'list of documents dated 23rd December 2026' while the earlier paragraph refers to 'list of documents dated 23rd December, 2025'
The court's name/station is printed as 'KEHANCHA', which may be a typographical error for Kehancha Law Courts
