Even as the appellee, or the respondent to the case being appealed, you may have incentive to file a cross-appeal. While the ruling of the original case came out in your favor, there may be portions of the law that were misapplied or decisions by the court that were applied incorrectly. There is some nuance to determining the value of a cross-appeal and how to file one effectively, which is why it is important to work with experienced lawyers if you are defending an appeal.
