If a political party leader officially calls for a referendum and submits it for the vote in the parliament this question will resolve to YES. (Currently Green Party advocates it but there is no concrete step.)

Edit and clarification: all that matters is if a vote is held for a referendum. Who initiates it and how, and even the result itself does not matter. If an actual decision is made to hold a referendum somehow in another way(very unlikely imho) it will still count.

Edit & clarification: I am personally participating in this market as the result should not be subjective.
