The similar legal regulation is specified in many federal laws concerning measures of social protection of the citizens ( About veterans raquo ;, About social protection of invalids in the Russian Federation raquo ;, About social protection of the citizens, undergone the influence of radiation, during the accident at the Chernobyl atomic power station and others). At presence of such legislative practice, nevertheless, it is possible to speak about absence of any constitutional principle, based in the given regulation. Considerable aid in the sanction of the given constitutional dispute has been rendered by the Convention of the International Organization of Labour No. 157 about establishment of the international system of preservation of rights in the sphere of social support (Geneva, June 21st, 1982, came into force for the Russian Federation on September 11th, 1986).
