Reverse Charge Applicability

In GST, Responsibility to pay tax is either on Suppliers of Goods/service (FCM) or Recipient of Goods/services (RCM).

In general, if suppliers charge GST in invoice, then there is no responsibility on recipient under RCM.
But if Good/service received by recipient is fall under RCM than recipient can't escaped it's responsibility under RCM, on ground that suppliers already charge GST in invoice.
