 Axiomatizations of CEU use a restricted version of the separability condition (the “Comonotonic” Sure-thing Principle or “Comonotonic” Tradeoff Consistency): namely, the condition only holds when all of the acts in its domain are comonotonic, i.e., when the worst-to-best ranking of the events coincides for all the acts (Gilboa 1987, Schmeidler 1989, Wakker 1989, Chew &amp; Wakker 1996, Köbberling &amp; Wakker 2003; see also Wakker 2010, who also notes the relationship between CEU and \(\alpha\)-maximin.)
