Abstract
It is proved that no non-meager subspace of the space equipped with the Ellentuck topology does admit a Kuratowski partition, that is such a subset cannot be covered by a family of disjoint relatively meager sets such that has the Baire property (relatively) for every subfamily . It is also shown that the existence of Kuratowski partitions is not a metric problem. Some remarks concerning continuous restrictions of functions with domain in the Ellentuck space are made.
