The Reply Brief
This is your opportunity to reply to the arguments made in the Response Brief. Use the same basic format as the Opening Brief, but address the points from the Response Brief.
It helps if you can show the Respondent was off point in a response.
It also helps if you can show precedent(s) to contradict the response(s).
Having filed your Reply Brief in a timely manner, you get to decide about the next step, Oral Arguments.
