Abstract
An axiomatic treatment of an aggregation problem when the aggregated group is defined as a fuzzy group, was proposed by the author in a previous paper. In the present paper, the fuzzy majority rule is characterized and an impossibility theorem for pure mixed rules is obtained. Moreover, existence of absolutely decisive groups is studied.
