General comments—evolving practice
The practice of issuing general comments began in 1981 with the Human Rights Committee pursuant to ICCPR Article 40.           Eight of the nine core UN human rights treaty bodies have issued a combined 153 general comments on various aspects of their respective treaties. 15 These include the CERD Committeew (thirty-five comments), the Human Rights Committee (HRC)17 (thirty-five comments), the ESCR Committee!® (twenty-three comments), the CEDAW Committee!® (thirty- four comments), the CAT Committee2° (three comments), the CRC Committee2i (nineteen comments, including one draft comment published June 2015), the Committee on Migrant Workers22 (two comments), and the newest treaty body to commence operation, the Committee on the Rights of Persons with Disabilities (two comments). Most recently, the ESRC Committee adopted General Comment 23 on the right to justice and favourable conditions of work in March 2016.23 The debate amongst observers of the UN human rights regime assigns disparate levels of importance to these comments as a form of soft law. Some view them as authoritative interpretations of the treaties while others view them as unsystematic and unfounded statements deserving no recognition in the lawTh Though there is far from consensus on the determination of exactly what legal weight general comments carry, it is evident that they have influenced the protection of human rights and enriched the human rights dialogue.
