This is a copyright infringement action involving computer software code. Pursuant to a consent decree, the district court appointed a special master to review the software and to opine on the issue of infringement. The special master found copyright infringement and submitted a report containing his analysis. The district court agreed with the special master that copyright infringement had occurred, adopted the special master’s report, and ordered all copies of the infringing software destroyed. Defendants appeal from the district court’s order. We have jurisdiction under 28 U.S.C. § 1291, and we vacate the district court’s order and remand.
