Section 31. How bills may be amended

When a bill or joint resolution, passed by one house, shall be amended by the other, the question on agreeing to the bill, or joint resolution, as amended, shall be again voted on, by yeas and nays, in the house by which it was originally passed, and the result entered upon its journals; in all such cases, the affirmative vote of a majority of all the members elected to such house shall be necessary.
