A constitutional referendum was held in the Helvetic Republic on 25 May 1802.[1] Unlike the constitution approved in 1798, the new constitution, known as the Malmaison constitution, did not provide for any referendums.[1] Non-voters were assumed to have voted in favour of the new constitution, a measure put in place to prevent its rejection.[1] As a result, 72.17% of voters were deemed to be in favour.[1]
