PRINCIPLE STATEMENT

In its ordinary dictionary meaning the word 'consequential' means 'following as a result, or inference; following or resulting indirectly.' See the Concise Oxford Dictionary 5th Edition, Page o 258. The word has never been regarded as a term of art. A consequential order therefore made subsequent to a judgment which detracts from the judgment or contains extraneous matters is not an order made within jurisdiction because at that stage, having determined the rights of the parties by giving judgment for (the) plaintiffs as claimed the judge has become functus officio except for any act permitted by law or rules of court.

EXPLANATION / SCOPE

After delivering judgment, a court becomes functus officio—without further jurisdiction—except to make consequential orders giving effect to the judgment. Consequential orders must flow directly from the judgment; they cannot detract from it or introduce extraneous matters. Orders that alter substantive rights or vary the judgment exceed jurisdiction. Permissible consequential orders are those that implement or enforce what was already decided, not those that add new terms. The distinction preserves finality while allowing ancillary orders necessary for effective execution.
