The depositions were taken in two civil suits brought by the parents of slain Columbine student Daniel Rohrbough and a student who was injured in the 1999 massacre that left 13 students and a teacher dead.
The appeals court was asked to determine whether U.S. District Judge Lewis Babcock erred when he found the depositions should be sealed under the Federal Records Act.
The judges also ruled that Babcock did not err when he declined to allow an expert in youth violence to review the parents' depositions.
