If the parties to a case disagree with the conclusions of a forensic examination of a document's age, they often try to persuade the court to order an additional or second forensic examination. Such attempts usually fail.

The managing partner of the law firm Alliance Legal Consulting Group and the Head of the laboratory of the National Expert Bureau discuss this in a joint article.
