In a letter to Prime Minister Narendra Modi, Athawale said although successive government's have been "lavish" in their assurances in this regard, no action has been taken.
The RPI chief said that there has been "no accommodation" of any Judge belonging to either of the SC/ST community after Justice K G Balakrishnan demitted office as Chief Justice of India in 2010.
"In the light of the fact, there is a 5-year-gap in such appointment/elevation when there are two vacancies as on date, the lawful expectation could be fulfilled at least now," the letter said.
