Abstract
The existence of extremal (actually perfect) partitions for flows with finite entropy is a direct consequence of Rudolph's representation. The aim of this paper is to prove the existence of such partitions for any measurable flow. This result is achieved by using Rudolph's theorem in a study of entropy properties of tower automorphisms.
