Facts / Background:
The petitioner association challenged GST liability on services rendered to its members under various welfare schemes. 
It relied on the doctrine of mutuality, contending that services by an association to its members are not taxable. 
Amendments introduced by the Finance Act, 2021 inserted Section 7(1)(aa) deeming such transactions as taxable supplies retrospectively from 01.07.2017. 
The Single Judge upheld the validity of levy but struck down the retrospective operation, leading to cross appeals by both parties.

Court Decision:
The Division Bench upheld the constitutional validity of Sections 2(17)(e) and 7(1)(aa) of the CGST/KGST Acts, holding that the legislature was competent to treat transactions between an association and its members as taxable supplies. 
It held that the amendment validly removes the basis of the doctrine of mutuality for GST purposes. 
However, the Court held that giving retrospective effect to the amendment from 01.07.2017 was not legally sustainable on principles of fairness. 
Accordingly, retrospective operation of the amendment was set aside, while upholding its prospective applicability.
