Differentiation between "single executive body of a legal person" and "person having functions of the single executive body" In a company

The author analyses the problem of legal status of legal person's organ, which is still controversial today in the russian civil law. The article examines differentiation concepts «single executive body of a legal person» and «CEO of a legal person» in company. The difficulties appearing in delimitation of these concepts and differences in the contents of normative acts create certain difficulties in law-application, in particular in determination to the consequences caused by authority abuse by CEO of a legal person.
