In the present article one of indicators of efficiency of standards of the criminal legislation - legal equipment of criminal law is considered. The legal equipment as concept structural, establishes some requirements to rules of law, namely: availability of legal language, adequate way of designing of rules of law, legal language, and also social validity of rules of law. Exact observance of these requirements would provide completeness and clarity of the content of norms of criminal law. The generalized, estimated, variable, specialized concepts which aren't always available to the population occur in the criminal law. In this regard in article it is offered to bypass whenever possible at realization of legislative activity use of the concepts which don't have special value for establishment of public danger of act (for example, plunders) and for qualification of a criminal offense.

According to the authors, application in the law of estimated concepts leads to impossibility of ensuring unity of opinions of staff of judicial investigating authorities therefore the criminal law will always be in a personal assessment of the lawyer. Nevertheless, the criminal law can't be completely deprived of technical or specialized concepts for the reason that articles providing such concepts establish responsibility of special subjects. Variable signs can be allowed only on material structures of the criminal offenses providing occurrence of considerable large or especially large damage. In other cases the admissibility of variable signs would mean instability of the criminal law.
