Power of voters and domain of preferences where voting by committees is strategy-proof
\textit{S. Barbera}, \textit{H. Sonnenschein}, and \textit{L. Zhou} [Econometrica 59, No. 3, 595-609 (1991; Zbl 0734.90006)] introduced a restriction on the domain of individual preferences for which there exist a class of strategy-proof social choice functions, which they called voting by committees. The author gives a generalization of this restriction and shows that the restricted domain one obtains is the maximal one where voting by committees is strategy-proof except for extreme cases.
