The article is considering the question of a possibility to recover damages caused to a demandant by procedural activities of a defendant. The author examines the problem of property responsibility of a disputant in the context of violating the right to sue in a corporeal sense, and comes to the conclusion that the right to sue corresponds to independent obligation of a debtor, which is to refrain from activities that prevent a creditor from exercising “the right to enforcement”. A defendant’s performance of procedural activities violating this obligation is the basis for compensation of losses caused to a demandant.
