The year of 2018 was a year of anniversary of the adoption of the Universal Declaration of Human Rights. Though a non-binding document, a soft-law source, the UDHR has proven itself to be an inspiring source for international treaties as well as domestic bills of rights encompassed within constitutional legal orders of many countries.
The evidence is clear in the 1966 International Covenant on Civil and Political Rights and the International Covenant on Economic, Social and Cultural Rights, for example.
