Ohio constitution
Article II: legislative
Section 1d

Laws providing for tax levies, appropriations for
the current expenses of the state government and state
institutions, and emergency laws necessary for the
immediate preservation of the public peace, health or
safety, shall go into immediate effect. Such emergency
laws upon a yea and nay vote must receive the vote of
two thirds of all the members elected to each branch of
the General Assembly, and the reasons for such necessity
shall be set forth in one section of the law, which
section shall be passed only upon a yea and nay vote,
upon a separate roll call thereon. The laws mentioned
in this section shall not be subject to the referendum.
