But these possibilities being recognized, I was invited to find that the most probable of the various possible explanations of the shortage of the case of wine from the Thermopylae and the case of glass buttons from the Kvernaas was that they had never been taken into those ships, and that it was in error that the reports under s. 64 included them amongst the imported cargo. I should make that finding if it were material to do so, but I do not consider that it is. On the construction of s. 149, I am of opinion that the question whether the goods were imported is not for the Court to decide. Section 64 places upon the master and the shipowner the duty of making the report of the ship's cargo of goods for the port, and it appears to me that s. 149, taking as its starting point that the responsibility rests upon them to make a correct report, subjects them, in the event of goods not being produced which their report admits have arrived in the ship, to a qualified liability to pay the estimated amount of the duty which, on the footing that the admission accords with the fact, is payable under the Tariff. So understood, the section simply carries a step further the policy of the Act in making goods "subject to the control of the Customs" from the time of their importation (s. 30), giving the customs a right of examination (ss. 32, 49 (3)), forbidding any movement, alteration or interference except by authority of a Customs officer (s. 33), requiring "for the purpose of securing the due importation of goods" that they be entered and unshipped (s. 49 (3)), and making elaborate provisions for ensuring that the unshipping is subject to adequate safeguards for the revenue (ss. 36-41, 68-77). As O'Connor J. observed in R. v. Lyon [1] "the whole policy of the Customs Act, as indicated by a number of sections, is that, from the time of importation until the time of paying duty, the customs shall not lose control of the articles imported. That is indicated directly in s. 30, which provides that imported goods shall be subject to the control of the Customs from the time of importation until delivery for home consumption or exportation. The object of that provision, if it were necessary to give any reasons for its enactment, is obvious; if once goods go into home consumption, that is, into circulation, it becomes almost impossible to trace them. The only security the Customs authorities could have in such a case for the payment of duty would be in most cases the personal security of the importer. Therefore it is, if the Act is to be effective, that all through the dealings with the goods, from the time they are first imported until duty is paid, they must be kept under customs control" [2] . See also Baume v. The Commonwealth [3] . It may be added that although the owner of goods, if they have in fact been imported, is personally liable to pay the duty on them (s. 153), his liability may be difficult to enforce in a case where the goods are missing, for rarely will there be, in the absence of the goods themselves, any evidence admissible against him in a court of the fact of importation, and not always will such particulars of the goods be available as are needed for definite determination of the appropriate amount of duty. The master of a ship is in a position to know what cargo the ship brings into a port for discharge there, for, if he wishes, he can have cargo tallied into the ship at ports of loading and tallied out of the ship at intermediate ports. There are, no doubt, practical difficulties which may induce him to abstain from taking these precautions and to accept the risk of his inward manifests being erroneous; but he can make his choice. Through him, persons within the definition of "owner" are in a like position. But the customs have no means of knowing what the imported cargo consists of, so that they may compare it with the cargo later produced from the ship's custody. Again, the master and the "owner" are in the best position to see that, in accordance with s. 74, goods are not unshipped except pursuant to a collector's permit or an entry passed. Accordingly, s. 149, if construed in the sense I have stated, makes a perfectly congruous addition to the scheme of the Act.
