693.4. In this Book, except Titles V, VI.3 and VI.9, where a Minister other than the Minister of Revenue or a body replaces or revokes a certificate, qualification certificate or other similar document that has been issued to a person or a partnership, the following rules apply in respect of the document, unless a more specific similar rule applies to it:(a) the replaced document is null as of the date of its coming into force or of its deemed coming into force and the new document is deemed, unless it provides otherwise, to come into force as of that date and to have been issued at the time the replaced document was issued or is deemed to have been issued; and
(b) the revoked document is null as of the effective date of the revocation and is deemed not to have been issued, obtained or held as of that date.
Where a document is, without being replaced, amended by the revocation or replacement of any of its parts or in any other manner, the document before the amendment and the document as amended are deemed, for the purposes of this section, to be separate documents the first of which (referred to as the “replaced document”) has been replaced by the second (referred to as the “new document”).
Where, in the circumstances described in the second paragraph, a document is amended only for a part of its period of validity, the new document is deemed to describe both the situation prevailing before the amendment, as proven by the content of the replaced document, and the new situation, as proven by the content of the new document.
