Over the years, referendums have covered topics such as the legitimacy of General Augusto Pinochet's rule and the adoption of new constitutions in 1980, 2022, and 2023.
The current constitution, enacted in 1980, stipulates that binding referendums are required only in specific circumstances, such as when a constitutional reform is fully vetoed by the President and then re-approved by Congress.
Note: The percentages used in the "Yes", "No" and "Neither" columns are over the total of valid votes in each referendum.
The percentages used in the "Null" and "Blank" columns are over the total votes cast in each referendum.
In this case, the President can either sign the reform into law or call for a referendum.
