Louisiana constitution
Article 7
Section 2.2

(C) As used in this Section, the term "sold directly to the consumer for residential use" includes the furnishing of natural gas, electricity, or water to single private residences, including the separate private units of apartment houses and other multiple dwellings, actually used for residential purposes, which residences are separately metered or measured, regardless of the fact that a person other than the resident is contractually bound to the supplier for the charges, actually pays the charges, or is billed for the charges. The use of electricity, natural gas, or water in hotel or motel units does not constitute residential use.
