My Lord, The State of Madras v. Gannon Dunkerley,  1 SCR 379 – Good Law?
“It is interesting to note that a 7 Judge Bench in M/s. Vishnu Agencies (Pvt.) Ltd. v. Commercial Tax Officer, (1978) 1 SCC 520, doubted Gannon Dunkerley’s case by stating that its correctness would have to await a more suitable occasion in that the entry, namely, 48 of List II of the 7th Schedule to The Government of India Act had been narrowly construed. It may be pointed out that H.M. Seervai’s Constitutional Law of India, Vol. III, Page 2326 had this to say: “This decision was rendered in 1959 and was repeatedly followed, till a doubt was cast on its correctness in Vishnu Agencies by the obiter observations of Chandrachud J”.”
