Poll Roundup: Citizenship Chaos Sends Government To New Term Low

2PP Aggregate: 54.2 to Labor (+1 point in a week) - highest reading of term
Labor would win election "held now" with a large margin
Government has lost majority (for now) with two MPs recontesting their seats in by-elections

This week we've seen a highly unusual event in Australian political history: a federal government has lost its majority partway through a term.  This last happened in 1931.  The one-term Scullin government began its term with a robust 46 seats out of 75, but a by-election loss and defections to the opposition UAP and the Lang Labor split saw it whittled down to 35, following which it collapsed before the year was out.  What has happened to the Turnbull government, so far, is much less dramatic - two of its seats are vacant pending by-elections, and the government will recover majority status if Barnaby Joyce is returned, although it would then lose it again if John Alexander is defeated.

However, as the Section 44 eligibility issues continue to unfold (with the tabling of required evidence by December 1 expected to be the next step), we could well see more by-elections early next year in some much more difficult government seats.  The prospect of the government slipping into permanent minority, or perhaps even losing enough seats that it can no longer govern, is a real one.  There may also be by-elections in Labor and crossbench seats, but no incumbent government has gained a seat from an opposition in a federal by-election since 1920 so there would not be too much optimism regarding chances of gaining seats there.  My legally unqualified view, incidentally, is that the "hesitators" (those who filed to renounce UK citizenship too late for the process to complete by the close of nominations) are in trouble.  The references in previous cases to the taking of all reasonable steps as sufficient refer to a context in which a member cannot reasonably renounce an overseas citizenship, not one in which a candidate was needlessly slow about it.

Section 44 Strikes, But The Government Hasn't Lost Its Majority Yet

Many news sites have now claimed that, in light of today's dramatic Section 44 disqualification of Barnaby Joyce from Parliament by the High Court, the beleagured Turnbull government has now lost its majority.

This is an exciting claim, but it isn't actually correct.

Pending the holding of a by-election for the seat of New England, the government will, when the House of Representatives next sits, hold 75/149 seats, with one vacant.  74 seats will be held by other MPs.  75 is larger than 74.  75 is larger than half of 149.  75 divided by 149 is 0.5033557... .  It is more than 0.500000.

The government's new and very temporary position is no different mathematically to that of the Cook Liberal government in 1913, which won 38/75 seats.  The Cook government is widely referred to as having had a one-seat majority.
