Abstract:	Let (X,d) be a metric space The functionM:X^k 2^x defined by $M(x_1 ,,x_k ) = { x in X:sumlimits_{i = 1}^k {d(x,x_i )}$ is the minimum } is called themedian procedure and has been found useful in various applications involving the notion of consensus Here we present axioms that characterizeM whenX is a certain class of trees (hierarchical classifications), andd is the symmetric difference metricWe would like to thank the referees and Editor for helpful comments

Keywords:	n-Trees Consensus Median procedure Majority rule
