Madras HC quashes assessment orders rejecting Input Tax Credit (ITC) of assessee entirely on the ground that the GSTR-3B returns did not reflect the ITC claim; Perusing the operative portion of assessment order, HC observes that when the registered person asserts that he is eligible for ITC by referring to GSTR-2A and GSTR-9 returns, the assessing officer should examine whether the ITC claim is valid by examining all relevant documents, including by calling upon the registered person to provide such documents; Thus, permits assessee to place all documents pertaining to its ITC claims before the assessing officer, directs assessing office to pass fresh assessment orders.
