David Irving v Penguin Books and Deborah Lipstadt… (2000)
“ Subsequently, in their Summary of Case, the Defendants revised their case to allege that Irving broke an agreement he had made with the Moscow archive by (without permission) removing from the archive glass plates on which the diaries were recorded; having copies made of those plates and transporting two plates to London, where they were subjected to forensic tests. The Defendants allege that Irving’s conduct gave rise to a significant risk that the plates might have been damaged, rendering them of limited use to subsequent researchers. ”
