Rule 31. Serving and Filing Briefs
(a)
Time to Serve and File a Brief.
(1)
The appellant must serve and file a brief within 40 days after the record is filed. The appellee must serve and file a brief within 30 days after the appellant’s brief is served. The appellant may serve and file a reply brief within 14 days after service of the appellee’s brief but a reply brief must be filed at least 7 days before argument, unless the court, for good cause, allows a later filing.
(b)
Number of Copies. Twenty-five copies of each brief must be filed with the clerk and 2 copies must be served on each unrepresented party and on counsel for each separately represented party. An unrepresented party proceeding in forma pauperis must file 4 legible copies with the clerk, and one copy must be served on each unrepresented party and on counsel for each separately represented party. The court may by local rule or by order in a particular case require the filing or service of a different number.
(c)
Consequence of Failure to File. If an appellant fails to file a brief within the time provided by this rule, or within an extended time, an appellee may move to dismiss the appeal. An appellee who fails to file a brief will not be heard at oral argument unless the court grants permission.
