SECTION 45

Style of laws; division of laws; laws restricted to one subject; amendment or revival of laws by title only.

Each law shall contain but one subject, which shall be clearly expressed in its title, except general appropriation bills, general revenue bills, and bills adopting a code, digest, or revision of statutes; and no law shall be revived, amended, or the provisions thereof extended or conferred, by reference to its title only; but so much thereof as is revived, amended, extended, or conferred, shall be re-enacted and published at length.
