"18. We have referred to the provisions of the 1992 Act and Para 2.3 of the FTP to demonstrate the difference between amendment and clarification. The power to amend the FTP is exclusively vested in the Central Government whereas the power to clarify is vested in DGFT. On 31.8.2004, the Central Government vide Notification No. 1/2004-09 notified the FTP 2004-09. The Policy was announced on 31.8.2004. The Policy came into force from 1.9.2004. That Policy came to be amended vide Notification No. 31 dated 19.10.2005 issued by the Central Government under Section 5 of the 1992 Act by which the position came to be changed and, for the first time, import of second-hand photocopying machines imported under the "general" category came under the "restricted" category of imports, which made the importer to import the said machine only against a licence issued in that behalf. Why was that Notification necessary? By the said Notification, import of photocopying machines came to be restricted. It was provided that the said import shall be against a licence. Such a restriction could be placed only by an Amendment and not by Policy Circular(s). Hence, after 19.10.2005, secondhand photocopying machines came within the "restricted" category. Such a change of category has to take place by way of Amendment by Central Government under Section 5 of the 1992 Act. On the other hand, the three administrative/policy circular Nos. 16/03, 19/03 and 20/05 only refer to clarifications issued by DGFT pursuant to representations received by him from the Trade. These circulars are clarificatory and not amendatory in nature. Therefore, under the scheme of the Statute, one finds a clear demarcation between an amendatory provision and a clarificatory provision. Section 5 of the 1992 Act contemplates amendment to the FTP. It empowers only the Central Government to amend the Policy. This power is not given to the DGFT. It is not open to DGFT vide circulars to change categorization of items from the category of "free" to the category of "restricted" imports. This aspect is important for two reasons. Firstly, notification no. 31 dated 19.10.2005, quoted hereinabove, is an amendment to the Policy. It operates only from 19.10.2005. It recites that second-hand capital goods are importable freely. The Notification states that after 19.10.2005, however, import of second-hand photocopying machines will be allowed only against a licence. This amendment pre-supposes
