Abstract
We show that for a -ideal with a Borel base of subsets of an uncountable Polish space, if is (in several senses) a "regular" family of subsets from then there is a subfamily of whose union is completely nonmeasurable i.e. its intersection with every Borel set not in does not belong to the smallest -algebra containing all Borel sets and Our results generalize results from \cite{fourpoles} and \cite{fivepoles}.
