Ohio Referred Issue 1 was on the November 5, 1918 ballot in Ohio as a legislatively-referred constitutional amendment, where it was approved.
Referred Issue 1 was referred to the ballot via House Joint Resolution 34. It said that the state legislature could pass laws to provide against the double taxation that occurs from "the taxation of both the real estate and mortgage or the debt secured thereby, or other lien upon it." (Art. XII, Sec. 2)
The provisions of Referred Issue 1 conflicted with the provisions of another measure on the same ballot, Initiated Issue 3. Initiated Issue 3 also won a majority of the vote, with 52.51% in favor. In the court case State ex rel. v Fulton (99 O.S. 168), it was decided that since Initiated Issue 3 conflicted with Referred Issue 1, even though both of the measures won an absolute majority, only the measure that won the highest majority would go into effect. That meant that Referred Issue 1 became law, while Initiated Issue 3 did not.
