With usage of phenomenological methodological instruments there is connected the perception of legal position as specific vision-understanding assuming legal evaluation of the situation and formation of corresponding senses and meanings. Marked are factors, which affect transformation of variable legal meaning as well as form such property of legal positions as normativity. On the whole the research is held in phenomenological key with necessary detailing and deviations.
