: From another direction, it might be possible to create a Ranked Pairs version that does everything RP does but also elects from the uncovered set, even if it's not independent of covered candidates.

LIIA follows from independence of last-place alternatives and the construction of the River ordering, which means removing first-place candidates leads to the 2nd-place candidate winning. 2. The maximally-independent form of RP seems to be [[Stable voting]], but as you said, it violates monotonicity :( --[[User:Closed Limelike Curves|Closed Limelike Curves]] ([[User talk:Closed Limelike Curves|talk]]) 04:26, 1 March 2024 (UTC)
