Resolution of a dispute about the prescription content (right or duty?)

Often, the defendant refers to the right prescribed to him in the case when the claimant asserts that there is a duty of the defendant, relying on the same regulatory prescription. This is due to defects in legal structures that give rise to uncertainty in legal prescriptions. Interpretation of such constructions in judicial practice allows us to formulate some rules (algorithms) for resolving disputes about the prescription content. Presented word forms the legal prescriptions and the findings resulting from their combinations, in conjunction with the status of participants of disputable legal relations and certainty of prescription addressed to one or both subjects of the relationship. The paper presents the results of a research aimed at creating a computer program for information and technological support for making reasoned court decisions in cases of claim proceedings under the rules of the civil procedure code of the Russian Federation, created by S.B. Polyakov and I.A. Gilev.
