Has me wondering if there are rules on low-turnout union elections. Like, some referenda require either (1) a given share of the eligible voter pool to show up or (2) a given share of the eligible voter pool to vote one way or the other for the result to be binding. This was what infamously tanked the Scottish devolution referendum in the 70s - the referendum got just under 52% of voters in favor, but there was a requirement that the referendum also be supported by 40% of the electorate and that wasn't met.
