A multi-question referendum was held in Taiwan on 24 November 2018 alongside local elections. The referendum was the first since the December 2017 reform to the Referendum Act, which reduced the threshold for submitting questions to the ballot; under the new system, signatures from 1.5 percent of the electorate (around 280,000 people) were required to successfully put a question on the ballot, reduced from 5 percent previously.^[1]

Four other questions on the ballot concerned international games representation, nuclear power, coal power and a ban on imports of agricultural products and food from areas affected by the Fukushima nuclear disaster.^[6][7][8] The tenth question asked voters to reject Article 95-1 of the Electricity Act, which stipulated that all of the country's nuclear power generating facilities should be decommissioned by 2025.^[9] This question had originally been rejected by the CEC, though the commission reversed its decision after being ordered by the Taipei High Administrative Court to accept an additional 24,000 signatures added to the petition.^[9]
