Section 1

Amendments to this constitution may be proposed in the senate or house of
representatives. Proposed amendments agreed to by two-thirds of the members elected to and
serving in each house on a vote with the names and vote of those voting entered in the
respective journals shall be submitted, not less than 60 days thereafter, to the electors at the
next general election or special election as the legislature shall direct. If a majority of electors
voting on a proposed amendment approve the same, it shall become part of the constitution
and shall abrogate or amend existing provisions of the constitution at the end of 45 days after
the date of the election at which it was approved.
