Bills may originate in either house and be amended or rejected in the other; and every bill shall be read on three different days in each house unless two-thirds of the house where the same is pending shall dispense with the rules; and every bill shall be read in full immediately before the vote on its final passage; and every bill having passed both houses, shall be signed by the president of the senate and the speaker of the house of represenatives, in open session; but before either shall sign any bill, he shall give notice thereof, suspend business in the house over which he presides, have the bill read by its title, and on the demand of any member, have it read in full; and all such proceedings shall be entered on the journal.
