Under La. Code Civ. P. art. 2133, an appellee can file an answer to an appeal to obtain relief against the appellant that the trial court denied. The answer is “equivalent to an appeal on [the appellee’s] part from any portion of the judgment rendered against [the appellee] in favor of the appellant ....” But Article 2133 does not say which court to file the answer in. Since the deadline to file it is 15 days after the record is lodged in the court of appeal, usually the answer is filed in that court. But some Louisiana decisions hold that it’s okay to file the answer in the trial court (presumably before the record lodged in the court of appeal). The most recent example is a decision last month on rehearing by the Third Circuit, Boudreaux v. Take 5 LLC, 22-44 (La. App. 3 Cir. 12/14/22). The Boudreaux court followed the First Circuit’s 2016 decision in Succession of Poole, 2015-1317 (La. App. 1 Cir. 10/28/16), 213 So. 3d 18, which is discussed in this 2017 blog post.
My suggestion: if you’re going to file an answer in the trial court (which I don’t recommend), do it well before the record is lodged in the court of appeal, so that the answer will be included in the record before the court of appeal. In Boudreaux, the appellee filed his answer the day before the return date for lodging the record, and the answer was included in a supplemental record lodged in the Third Circuit. The result might have been different if the appellee filed his answer after the return date for lodging the record; in that case, the answer would not have been in the record for the Third Circuit’s consideration.
