With great respect, we think that such an extraordinary result has only to be stated to suggest that the argument is untenable. It would denude the obligation imposed by Art. III, r. 2 of much of its substance. There is a more persuasive answer ready to hand to explain why Art. IV, r. 2 does not expressly preserve liability for negligence in all cases. It is that pars. (c) to (o) inclusive, with the exception of (l), are all matters which in themselves are beyond the control of the carrier or his servants. Any reference in that context to negligence is inappropriate, because they are events which of their nature occur independently of negligence on the part of the carrier. For example, one would not expect to see the rule relieve the carrier from responsibility for damage resulting from "act of God, unless caused by the fault or neglect of the carrier, his agents or servants". The remaining paragraphs of r. 2 carry their own explanation. Paragraph (a) has its origin in s. 3 of the Harter Act, and has attracted a particular history (cf. Gosse Millerd [45] . Paragraph (b) relates to fire, and reflects its own particular statutory history (see the Merchant Shipping Act, 1894 U.K., s. 502). Paragraph (l) deals with deviation to save life and property, and receives fuller treatment in Art. IV, r. 4. Paragraph (q) is of the greatest assistance in the task of construction, because in our opinion it expresses the fundamental scheme of the Rules. That scheme is to impose certain responsibilities and liabilities on the carrier of goods by sea, from which he cannot contract out (cf. Art. III, r. 8), but to give him immunity in respect of loss or damage caused otherwise than by negligence for which he is responsible, save in the special cases to which we have referred. To the extent to which Art. III, r. 2, by using the word "properly" imposes on the carrier a more onerous duty than an absence of negligence then clearly to that extent the immunities described in Art. IV, r. 2 operate to qualify the liability otherwise resting on the carrier; indeed, if this is not the case then as Temperley points out in his monograph, Carriage of Goods by Sea Act 1924, 3rd ed, p. 48, par. (q) is not an immunity at all, for it would do no more than shift the onus of proof on to the carrier. On the other hand, if such a line of reasoning seeks to extract a greater symmetry of purpose than the Rules viewed in their entirety will admit, then the proper observation is simply that it must not be thought that the effect of the prefatory words to Art. III, r. 2 is to compel some impact on the scope and operation of the obligation imposed by that rule from every provision in Art. IV. Ample justification for the preface is to be found in the presence in Art. IV of r. 2 (a) and (b), and rr. 4, 5 and 6. Each of these provisions adds a significant qualification to either the scope of the obligation or the consequences of a breach. There is then nothing surprising in the fact that those paragraphs of Art. IV, r. 2 which do not depend on any conduct of the carrier, his agents or servants, have nothing to say to Art. III, r. 2. Other rules in Art. IV also provide the carrier with important immunities: the right to deviate in certain circumstances (r. 4), the right to deal with dangerous goods (r. 6), and a limitation on the quantum of damage for which he is liable (r. 5).
