While electoral threshold is quite common within party-list PR system, I'm curious whether it is possible to implement something similar within single-transferable vote (STV) system.
The problem is of course that STV has several rounds of vote counting, which raises the question which round do you use as benchmark to measure whether it has crossed the electoral threshold?
Moreover, while you can arguably implement an electoral threshold for candidates in STV, is it even possible to implement a threshold for political parties under this system?
Would be helpful if we can look at real-life examples.
