Section 16 (2) (c) - Goods and Services Tax - GST

One of my client purchased goods and paid to supplier during FY 2018-19. Supplier filed GSTR-1 properly and filed GSTR-3B Nil. Later department cancelled supplier s GST no with retrospectively. Now the SCN issued by department to us referring section 16(2)(c) of the CGST Act for payment of tax with interest as the supplier did not deposited the amount to department. What remedy available to us. Please refer case law also in tax payer s favor.
