Held, the true test, is in interconnection and independence - in addition to geographical proximity and commercial nexus. There is no finding, nor even a suggestion, by any of the authorities below to the effect that the three contracts are inextricably interconnected, interdependent or can only be seen only as a coherent whole in conjunction with each other. As a matter of all the three contracts are for three different purposes- for charter of accommodation barge, for use of barge in domestic are and for replacement of decks. None of these contracts are such that these can be viewed as interconnected or interdependent. The CIT(A) was thus quite justified in holding that the duration of these projects cannot be aggregated for the purposes of ascertaining whether or not the permanent establishment of the Assessee can be said to have existed in India. It is an admitted position that unless the time spent on these different contracts is aggregated, the threshold limit of nine months, as laid down in Article 5(2)(i), cannot be satisfied. In view of these discussions, and bearing in mind entirety of the case, we hold that the CIT(A) was quite justified in holding that the Assessee did not have a permanent establishment in India.
