What action can be taken by the proper officer for contravention of any provisions of composition levy and how?

Where any contravention is observed by the proper officer wherein the registered person was not eligible to pay tax under the composition scheme or has contravened the provisions of the CGST Act, 2017 or provisions of Chapter II of the CGST Rules, 2017, he may issue a notice to such person in FORM GST CMP-05 to show cause within fifteen days of the receipt of such notice as to why the option to pay tax under the composition scheme shall not be denied.
Upon receipt of the reply to the said show cause notice in FORM GST CMP-06, the proper officer shall issue an order in FORM GST CMP-07 within a period of thirty days of the receipt of such reply, either accepting the reply, or denying the option to pay tax under the composition scheme from the date of the option or from the date of the event concerning such contravention, as the case may be.
