The treaty system of the European Social Charter is an integrated set of international standards concerning social rights and a mechanism for monitoring their implementation within the States concerned.

Taking into account the evolution which has occurred in Europe since the adoption of the European Social Charter in 1961, the Revised European Social Charter, adopted in 1996, embodies in a single instrument all the rights guaranteed by the 1961 Charter and its Additional Protocol of 1988, while up-dating some of them and adding several completely new rights.

The Revised Charter is gradually replacing the initial 1961 treaty.

Enforcement of the Revised Charter within the States parties is submitted to the same monitoring mechanism as the 1961 Charter, i.e. the reporting system; this system was developed and strengthened in 1991 by an Amending Protocol (the 'Turin Protocol'). For the States parties which have accepted it, the reporting system is complemented by the collective complaints procedure, based on the relevant Additional Protocol of 1995.

Today, the Charter treaty system is one of the most widely accepted human rights set of standards within the Council of Europe. The widespread support for social rights is assured by the fact that 42 out of the 46 member States of the Council of Europe are Parties to either the 1961 Charter or the Revised Charter.
