The purpose of Reply Brief is to tackle new issues or argument raised in the respondents’ Brief of Argument and not dealt with in the appellant’s Brief of Argument otherwise a Reply Brief would be tantamount to a repetition of the appellant’s main Brief. In other words, it should not serve as a forum for reopening the appellant’s case over again. And where it is coterminous in every respect with the appellant’s main Brief, it should be discountenanced.
