15. No deed, document or writing is binding on the department or may be attributed to the Minister unless it is signed by him or by the Deputy Minister or by another civil servant, and only, in this last case, to the extent determined by regulation of the Government published in the Gazette officielle du Québec.
The Government may, however, upon the conditions it fixes, allow the required signature to be affixed by means of an automatic device to such documents as it determines.
The Government may also allow a facsimile of the required signature to be engraved, lithographed or printed on such documents as it determines; in such case, the facsimile has the same force as the signature itself if the document is countersigned by a person authorized by the Minister.
