Generate text that refutes this claim: Significant changes in the past have not been put to popular vote.  In the past treaties with more far reaching consequences have been ratified by ruling parliaments without ever going to popular vote. For example the 1986 Act establishing a Single Market and the 1996 Maastricht Treaty. These treaties gave the EU power in economic regulation, immigration and monetary policy and yet were not put to majority voting. It was understood that progress was important and popular voting could halt progress. If these changes were made it is nonsensical that treaties with less significance should use a referendum.

The lack of referendums in the making of past decisions is not reason enough to neglect democracy in the present. Decisions that were made by past governments should be made accountable by present governments, because voting has been denied in the past gives even more reason to now open up these important decisions to popular vote.
