In fact, I searched for some case laws in this regard, Saswata, but in vain. A case law earlier I came across some time back about the question of appropriate Govt, whether Central or State, in respect of a factory being run in a different State but owned by a Limited Company registered and functioning from another State held that the appropriate Govt was the State Govt, distinguishing a factory u/s 3(a) of the PGA,1972 and the other establishments mentioned under the same section. This point compelled me to delve deep into the proposition you made as it appeared relevant to the case in point and come to the conclusion stated supra. Thank you for your mind-boggling question.
