One of the leading roles in establishing 
international labor standards is played 
by the generally recognized principles of international labor law.
The problem of generally recognized principles of international law has been deeply studied from theory by such scientists as G. I. Tunkin, V. L. Tolstykh, relating them to the norms 
of customary international law, the norms of juscogens [1, p. 140; 2, p. 227]. Ather scholar A. 
Kh. Abashidze comes to the conclusion that an 
analysis of international judicial practice, mainly of the International Court of Justice, confirms 
that the courts do not distinguish between applied principles.
