Del. Const. art. XIII, § 1
The General Assembly may from time to time provide by law for the submission to the vote of the qualified electors of the several districts of this State, or any of them, mentioned in Section 2 of this Article, the question whether the manufacture and sale of intoxicating liquors shall be licensed or prohibited within the limits thereof; and in every district in which there is a majority against license, no person, firm, or corporation shall thereafter manufacture or sell spirituous, vinous, or malt liquors, except for medicinal or sacramental purposes, within the district, until at a subsequent submission of such question a majority of votes shall be cast in the district for license. Whenever a majority of all the members elected to each House of the General Assembly by the qualified electors in any district named in Section 2 of this Article shall request the submission of the question of license or no license to a vote of the qualified electors in the district, the General Assembly shall provide for the submission of such question to the qualified electors in such district at the next general election thereafter.
