Summary.
We show that Arrow's condition of independence of irrelevant alternatives is logically related to conditions of consistency of choice (in particular, to Arrow's choice axiom). The relation, however, is indirect. The link is provided by an independence condition due to Hansson (Synthese, 1969) which applies to fixed agenda social choice rules.
