A bench comprising Chief Justice J S Khehar and Justices D Y Chandrachud and S K Kaul sought the government's response by March 10 on the PIL seeking filling up of vacancies in the commission, which does not have any member at present.
NCSC, a statutory body formed under Article 338 of the Constitution, is a five-member body comprising a Chairperson, Vice Chairperson and three members.
It said that after the demission of office by the remaining two members on March 4 and 5, "the commission has become defunct and inoperative and on account of the same, the public in general will suffer at large."
"That the inordinate delay on the part of the government is costing the people profusely," it said, adding that this might prejudice the interest of the schedule caste.
The plea also sought extension of the tenure of a woman member, who demitted the office on March 5, "to safeguard the interest of scheduled castes".
