@ Shri Padmanathan Ji,
W.r.t. your last post, please let me add some more finer points to the ongoing discussion:
A. Just like delivery of goods, possession of goods need not be 'physical' but can be constructive.
B. This is what is meant by the explanation given u/s 16(2)(b) where having 'documents of title to goods' is treated as having possession or control on those goods. And having possession or control on those goods by the recipient is treated as deemed receipt of those goods for purpose of Section 16(2)(b).
C. I do not think even Sales Tax Act, 1930 contradict above position, though I would not want to use its delivery-related provisions (at first stage / as opening argument) purely because I find said explanation very clear & unambiguous and to avoid distraction from main argument. Of course, I can & will use provisions of Sales Tax Act, 1930 to explain how contrary view-point's reliance of them is grossly misplaced.
C1. Even otherwise, under GST, the terms "delivery" & "Possession" - themselves - are treated as 'different' as can be seen from Section 2(93)(b) of the CGST Act, 2017. So, entire focus of delivery-related provisions of Sales Tax Act, 1930 to link 'delivery' to 'physical receipt & then, physical possession' is faulty in my humble opinion. Under said explanation, 'delivery' is linked to 'documents of title to goods' (i.e. possession or control on those goods by the recipient) on deeming basis for purpose of Section 16(2)(b).
D. Said explanation is actually put in place, IMHO, so as NOT to limit availability of ITC only on physical receipt of those goods but to SPECIALLY ALLOW the ITC even when there is constructive delivery of goods to the recipient registered person by way of transfer of documents of title to goods.
E. Any contrary reading of that explanation (to the effect where availability of ITC to the recipient is made dependent solely upon physical receipt of those goods) is blatantly contrary to plain, simple & unambiguous reading of said explanation IMHO.
F. Also, limiting said explanation only to 'Bill To Ship To' nature of supply and NOT extending to 'One To One' contradict first part of the explanation itself (i.e. where the goods are delivered by the supplier to a recipient or .........). Moreover, this view also ignores crucial difference between wordings of this explanation and wordings of Section 10 (1) (b) of the IGST Act, 2017 which actually deals with 'Bill To Ship To' nature of supply by using the word "third person" which NOT used at all in this explanation u/s 16(2)(b).
F. There is many more real-life examples where ITC is taken by the recipient registered person - across many industries - without physical receipt of those goods but only on the basis of constructive deliveries (& thereby, constructive-receipt). For example: Dies / Mould sold by component manufactures to Original Equipment Manufacturers / OEM (like Baja Auto, Tata Motors, Hero, even in other industries like Washing Machine, Refrigerators & so on) without removal from factory (& using them for manufacturing components for these OEM/s). And, I do not think these OEM/s are contravening Section 16(2)(b) at all by taking ITC against these moulds / dies without physically receiving them.
These are ex facie views of mine and the same should not be construed as professional advice / suggestion.
