Furthermore the exclusive nature of the corpus is indicated in such a statement found in the Preamble that from thenceforth any text without the Three Seals should never be used in the administration of justice. It is not unlikely that all of pre-KTSD legal text should have been left abandoned at the time of or after the completion of the whole corpus, if not intentionally having been destroyed. So far no legal text predating the KTSD is in existence.
