That would depend on the copies and how you recv them . If you made copies with out permission or took them from where they belonged to another place to make copies you would be in more trouble then the copies would be good for .

If you signed for them on their release form and they provided you with the copies then yes you can enter them into your case .

Also just a FYI - the judge will ask both sides to present proof of the copies in question . So keep your rec or ask for a copy of the release form that you signed to recv them .
