(a) Except as specifically provided in the Kansas liquor control act, the power to regulate all phases of the manufacture, distribution, sale, possession, transportation and traffic in alcoholic liquor and the manufacture of beer regardless of its alcoholic content, is vested exclusively in the state and shall be exercised as provided in the Kansas liquor control act. No city or county shall enact any ordinance or resolution which is in conflict with the provisions of the Kansas liquor control act and any such ordinance or resolution shall be null and void.

(b) Nothing contained in this section shall be construed as preventing any city from enacting ordinances declaring acts prohibited or made unlawful by this act as unlawful or prohibited in such city and prescribing penalties for violation thereof, but the minimum penalty in any such ordinance shall not be less than the minimum penalty prescribed by this act for the same violation, nor shall the maximum penalty in any such ordinance exceed the maximum penalty prescribed by this act for the same violation.

(c) The provisions of this act are severable. If any provision of this act is held to be invalid or unconstitutional, it shall be presumed conclusively that the legislature would have enacted the remainder of this act without such invalid or unconstitutional provision.
