Ranked Pairs satisfy Local Independence of Irrelevant Alternatives criterion, but I got curious if this property is obtained independently of locking order. For context, ISDA comes independently of locking order, but ISDA is implied by LIIA + Majority criterion, so I got curious if LIIA is what actually is obtained and ISDA simply followed from it. I tried to create a proof for a positive result, but quickly discovered I could not figure out how to cover scenarios containing multiple matchups to be locked in at the same time. Any help would be much appreciated. Gustav P.S: I have started to suspect I need to fail LIIA for a MMPO locking order to satisfy all of AFB+Mono+LN-Harm+MB-ISDA unless LIIA satisfaction is automatic independently of locking order, and then figured it was interesting enough of a question on its own. ---- Election-Methods mailing list - see https://electorama.com/em for list info
