A Reply Brief is meant to explain or contest fresh issue of law raised in the Respondents brief, which was not canvassed in/by the Appellants Brief. – Mbaba JCA. Aduba v. Aduba (2018)
It is therefore clear that paragraph 16(1) of the First Schedule to the Electoral Act does not permit a Petitioner in his Reply to introduce or bring in any new issue or fact which ought to have been raised in the petition itself. In other words, a Petitioner cannot in the guise of a Reply to a Respondent’s Reply, introduce a new issue of fact which was never raised in his Petition nor raised by the Respondent. To do that will amount to amending or adding to the petition, and also taking the Respondent by surprise because at that stage, the Respondent will not be in a position to react to such new issue or fact. It will therefore breach the Respondents fundamental right to fair hearing. Therefore, the Petitioner is not permitted to repair or rehash his averments in the Petition in such a way that it will amount to an amendment or reconstruction of the petition. See Dingyadi v. Wamako (2008) 17 NWLR (pt. 116) 395.
