The issue considered by the Court was whether the exclusion of “services” relatable to Entry 41 of List II of the Seventh Schedule from the legislative and executive domain of the NCT of Delhi, vide a notification of the Government of India dated May 21, 2015, is unconstitutional and illegal.
Since the judges on the Bench differed, that aspect was referred to a larger Bench and it came up before a three-judge bench.
The three-judge bench then referred the matter to the Constitution Bench on Centre’s request.
