The article examines in detail the logic basis of legal qualiёcation, the major stage of application of the law, the means of speciёcation of the provisions of the rule of law. Two blocks of logic rules to be observed in the course of legal qualiёcation are analyzed: the organic laws of logic (identity, noncontradiction, the excluded middle, sufёcient reason) and the rules of construction of categorical syllogisms. The author afёrms that careful research of logic forms of legal qualiёcation used in the course of application of the law, will promote development and implementation of logical programmes (algorithms) of qualiёcation in the work of law enforcement authorities, ёrst of all, for “typical cases” and, hence, will lead to automation of this process, realization of “The Electronic Judge” programme, which has already been introduced in some countries, mainly Latin and Central America.
