Sh. Murari Agrawal Ji,
(i) Firstly, your queries are not naive. Your queries are well-drafted and thought provoking.
(ii) Please follow how you feel safe in the eyes of GST laws. No issue. I am posting my views just for discussion sake.
(iii) The words from 'unregistered to registered ' are for all the specified goods and services except here RCM Notification specifically allows a registered person who pays the freight (who bears the freight) by virtue of Explanation inserted in the Notification per se.
(iv) The purpose and significance of Explanation
"Explanation added to the notification also forms part of the notification itself and the notification has to be construed as a whole and in properly interpreting the notification, the explanation which has been added to the notification cannot be ignored. The question as to whether the explanation seeks to control the operation or the effect of the notification is indeed immaterial, as the explanation purports neither to control nor to alter but only seeks to explain. What the explanation provides is not in any way in conflict with or contrary to what the Notification No. 25/10 provides. [para 10]"--------Supreme Court in the case of COROMANDEL FERTILISERS LTD. Versus UNION OF INDIA AND OTHERS 1984 (8) TMI 80 - SUPREME COURT.
(v) An Explanation merely widens the scope of the main Section and is not meant to carve out a particular exception to the contents of main Section--Supreme Court in the case of Sonia Bhatia Vs. State of U.P. 1981 (3) TMI 250 - SUPREME COURT.
(vii) Hon'ble Supreme Court in the case of S. Sundaram Vs. Pattibhiraman - 1985 (1) TMI 306 - SUPREME COURT has observed the object of Explanation as under :-
(1) It is to explain the meaning and intendment of the Act.
(2) When there is any obscurity or vagueness in the main enactment, to clarify the same so as to make it consistent with the dominant object which it seems to subserve.
(3) To provide additional support to the dominant object of the Act in order to make it meaningful and purposeful.
(4) An explanation cannot in any way interfere with or change the enactment or any part thereof but, where some gap is left which is relevant for the purpose of preventing the mischief and advancing the object of the Act it can help or assist the true purpose and intendment of the enactment.
(5) It cannot curtail statutory right which any person under a statute has been clothed with or by becoming an hindrance in the interpretation of the same.
The explanation is superadded to clear up difficulties or obscurities.
Thus Notifications, Rules & regulations and circulars help/aid the Act.
