In Ecobank Plc v. Honeywell Flour Mills Plc (2018) LPELR 45124 (SC), it was held: I need to emphasize that the function of a Reply Brief is to answer the arguments in the Respondents brief which were not taken in the Appellants brief. It is not meant to be a repetition of the arguments in the Appellants brief. It is not an opportunity to re-emphasize the arguments in the Appellants brief.
A REPLY BRIEF CAN ONLY CONTAIN REPLIES TO NEW ISSUES RAISED BY RESPONDENT
It is not my understanding of the law of brief writing that a reply brief seeks a different relief outside the main brief. A reply brief, as the name implies, is a reply to the respondent’s brief. A reply brief is filed when an issue of law or arguments raised in the respondent’s brief call for a reply. A reply brief should deal with only new points arising from the respondent’s brief. In the absence of a new point, a reply brief is otiose and the Court is entitled to discountenance it. A reply brief is not a repair kit to put right, any lacuna or error in the appellant’s brief.
