On the basis of the analysis of court practice on disputes arising from corporate contracts, the author draws a conclusion about restraining of margin of appreciation of the corporate contract provisions with imperative provisions of laws on economic companies. A subject of the corporate contract is exercise of the corporate rights therefore waiver (abstention) can't be a subject of this contract. In the author's opinion correction of legislation about itemization and definition of the corporate contract's subject, effect of non-performance or violation of the corporate contract provisions, and also recognition of the corporate contract invalid in case of a contraversy to its law is necessary.
