We present a new extension of the Shapley value for games with communication structure,only pairwise meetings can occur when some of them are not permitted.The present extension is a new one and in particular it is di .erent from the Myerson value,from the position value,and from a previous value proposed by the author.The motor of this new axiomatization is an associated consistency axiom which has already been used in various contexts.Following this new value,the payment received by a given player in a unanimity game is the arithmetic average of the payments that this player would have received in a selection of smaller unanimity games.
