If this change happens, it will mean saying goodbye to yet another SNTV system. On the other hand, as best I can tell from David’s description, SNTV was de-facto already abandoned as of the most recent election. In that election, they used a rather odd system of “ghost districts” that I am not sure that I really understand; it seems as if each wider electoral district was subdivided into M sub-districts (where M is the district magnitude), and that each candidate had to beat out only the other candidates in the “ghost” district to win. In other words, it was mechanically FPTP, as the winners would not necessarily be the top M in votes over the wider electoral region. The twist is that no one actually knew which candidates were competing against which other ones for a given seat–that’s the “ghost” aspect. Weird.
