The Condorcet loser criterion states that "if a applicant would drop a head-to-head Level of competition versus every other prospect, then that candidate need to not gain the general election". IRV (like all voting procedures using a remaining runoff round) satisfies this criterion, since the Condorcet loser can't get a runoff, even so IRV can still elect the "second-worst" prospect, once the two worst candidates are the only ones remaining in the ultimate spherical.[53] nonetheless, this is not likely.

Medium-sized events, like the nationwide get together of Australia, can co-exist with coalition companions like the Liberal bash of Australia, and might compete from it without concern of getting rid of seats to other parties due to vote splitting, Though commonly in practice these two get-togethers only contend against each other each time a sitting down member of your coalition leaves Parliament.
