fu the present case the Customs authorities did not direct pro· secution for contravention of any condition of a licence : they directed confiscation of the machinery and imposed penalty in lieu thereof. But on the terms of ~. 5 as amended, the right to impose penalty for contravcintion of any condition ·of a liccDCe may be exercised under the Sea Customs Act, 1878, and not under the Imports and Exports (Control) Act, 1947. For breach of any condition of a licence, it is open to the authorities to direct prosecution, but no order confiscating goods and imf.OS· ing penalty in lieu thereof could be made. The order of confiscation could only be made under s. 167 cl. 8 of the Sea Customs Act, 1878 : in terms cl. 8 of s. 167 provides for confis· cation of the goods importation or exportation of which is for the time beiag prohibited or restricted by or under Ch. IV of the Sea Customs Act, 1878. The notification of which the contravention is said to have been made, is not issued under s. 19 of the Sea Customs Act, but under the Imports and Export5 (Control) Act, 1947. It has not been urged before us, and rightly, that penalty of confiscation is incurred under the provisions oi the Sea Customs Act, 1878, for breach of the conditions of the licence.
