§ 40. Certificate of presiding officer. Upon the passage by either house of the legislature of a bill, concurrent resolution proposing amendments to the state constitution, or concurrent resolution proposing or ratifying amendments to the constitution of the United States, the presiding or other officer designated by the rules of such house shall append to such bill or resolution a certificate, to be signed by him, which shall disclose the date of its passage in such house, and whether passed by the votes of a majority of all the members elected to such house or of two-thirds thereof, or of a majority of such members, three-fifths thereof being present. In addition, if any such bill has been passed on a message required by the constitution, that fact also shall be stated, and if the message so specifies, the applicable portion of the constitution shall be identified. Upon the passage of a bill as to which a part becomes law immediately and a part requires further action by the governor, two copies shall be certified as above provided, one of which, upon final passage by both houses, shall be transmitted to the governor and the other to the secretary of state. No bills shall be deemed to have so passed unless certified in the manner provided by this section, which certificate to such effect shall be conclusive evidence thereof.
