The Congress spokesperson said the Supreme Court's words are respected by all including the government and the press.
"Even you do not comment on that," Afzal said.
He did not give an specific answer on to whether the party endorses the Singh's remarks.
Pressed on Congress' views on the issue, he said, "The party's view is only that whatever observations the Supreme Court has made, they should be taken seriously".
Digvijaya Monday took a dig at the Supreme Court over its observation that CBI was a "caged parrot", suggesting the description was "belittling" the country's institutions.
Singh's veiled criticism of the judiciary was quickly condemned by the opposition BJP which advised the AICC general secretary to "learn and understand" why there were a "series of scams" in the UPA government instead of "blaming the judiciary".
