The Crossbench That Holds the Balance
A state lower house has 59 seats. After an election the major parties hold 26 (Party A) and 24 (Party B). Five independents hold the remaining nine seats, but two of those independents have signed a confidence-and-supply agreement with Party A committing them to vote with the government on budgets and no-confidence motions only. The remaining three independents (X, Y, Z) have made no commitments. Party A wants to pass a bill that requires a simple majority of members voting. Independent X will support the bill; Y will oppose it; Z says she will abstain unless the bill contains an amendment she has proposed. Party B and all its members will oppose the bill. Two of Party A's own members have signalled they may cross the floor because the bill cuts funding to their regional electorates.
1. Calculate the minimum number of votes the bill needs and identify, with reasoning, the most fragile point in the government's position.

A simple majority of members voting is needed. With 59 seats, if everyone votes, the threshold is 30. The government bloc is Party A's 26 plus the two confidence-and-supply independents = 28, but those two are only bound on budgets and confidence motions, so on this ordinary bill they are free agents - the government cannot count them automatically. Party A's realistic committed support is 26, plus X = 27. Party B's 24 plus Y = 25 oppose. Z abstaining leaves the bill at 27 for, 25 against, which passes with a bare two-vote margin. The fragile point is the two potential floor-crossers: if both vote against, the count becomes 25 for, 27 against and the bill fails. If only one crosses, it is 26–26 and fails on a tie (the Speaker's casting vote conventionally preserves the status quo). So the government's real task is not winning Z but holding its own members, and Z's amendment is leverage the government can use to keep its regional members on side.
2. Advise the government on the strategic sequence it should follow, explaining how the concepts of mandate and representation bear on the choice.

The government should first secure its own party room before negotiating outward, because its arithmetic collapses with a single defection. Concretely: (1) negotiate with the two regional members, using Z's amendment or a funding guarantee as the currency; (2) only then approach Z, since conceding her amendment costs nothing if it also buys back the crossbenchers; (3) treat the confidence-and-supply independents as a reserve, not a resource, because relying on them on an ordinary bill would breach the agreement and destroy trust. On mandate: the government can claim an electoral mandate to legislate, but a mandate is a political claim, not a legal power - it cannot bind independents who owe their seats to local constituencies. On representation: the crossbench is doing exactly what a Westminster-derived system with single-member seats permits - representing local interests at the point of decision. The government should frame any concession as responsiveness to regional representation rather than as weakness, because the alternative framing invites the charge that it is being held to ransom.
