Or. Const. art. I, § 39

The State shall have power to license private clubs, fraternal organizations, veterans' organizations, railroad corporations operating interstate trains and commercial establishments where food is cooked and served, for the purpose of selling alcoholic liquor by the individual glass at retail, for consumption on the premises, including mixed drinks and cocktails, compounded or mixed on the premises only. The Legislative Assembly shall provide in such detail as it shall deem advisable for carrying out and administering the provisions of this amendment and shall provide adequate safeguards to carry out the original intent and purpose of the Oregon Liquor Control Act, including the promotion of temperance in the use and consumption of alcoholic beverages, encourage the use and consumption of lighter beverages and aid in the establishment of Oregon industry. This power is subject to the following:

(1) The provisions of this amendment shall take effect and be in operation sixty (60) days after the approval and adoption by the people of Oregon; provided, however, the right of a local option election exists in the counties and in any incorporated city or town containing a population of at least five hundred (500). The Legislative Assembly shall prescribe a means and a procedure by which the voters of any county or incorporated city or town as limited above in any county, may through a local option election determine whether to prohibit or permit such power, and such procedure shall specifically include that whenever fifteen per cent (15%) of the registered voters of any county in the state or of any incorporated city or town as limited above, in any county in the state, shall file a petition requesting an election in this matter, the question shall be voted upon at the next regular November biennial election, provided said petition is filed not less than sixty (60) days before the day of election.

(2) Legislation relating to this matter shall operate uniformly throughout the state and all individuals shall be treated equally; and all provisions shall be liberally construed for the accomplishment of these purposes.
