Irrelevant Vs. Clone (was RE: [EM] IRV in San Francisco)

[bql at bolson.org]

In a method that mistreats clones, a clone is an "irrelevant alternative". 
Dropping a non-winning clone, allowing the other non-winning clone to win, 
violates the desired independence of irrelevant alternatives.

Thus, everything that violates the clone criterion, violates independence 
of irrelevant alternatives. I think that makes ICC a subset of IIA.
