There was a possibility that the referendum on joining the European Union in Lithuania could have failed, not because the Lithuanians could have voted against it (92 percent were in favor last I recall), but because Lithuania has a really stupid system on referendums where over half of all eligible voters need to cast their vote for the yes option for the motion to pass, not just those who showed up.
It's most likely that the government of Lithuania would have moved on to get the country in the EU regardless, there is no specific requirement for an EU application to be approved by referendum, but it's interesting to consider regardless.
