539. The certificates issued by the Inspector General, the duplicates of articles attached thereto and all documents issued by the Inspector General under this Act shall be held as authentic.
The signature of the Inspector General on copies of documents, registers and records is proof of the fact that these documents exist and are lawfully in his possession.
Any copy signed by the Inspector General is equivalent to the original itself in any court of justice, and any document or copy purporting to bear his signature is deemed to do so until proof of the contrary.
Every copy of the registration made at full length of articles and other documents which must be registered under this Act, duly certified by the Inspector General, is deemed authentic and is evidence of their registration, and has the same effect as the production in court of the articles or documents.
