(1) of S. 396, it is said, is at least ambiguous and, since it was passed for the purpose of giving legislative effect to the rules agreed upon it is contended that the meaning which should be adopted is that which will produce this result.
There can be no doubt that the Salvage Convention was concerned with all salvage claims. Article 1 provided that assistance and salvage of sea-going vessels in danger, of any things on board, and of freight and passage money, should be subject to the ensuing provisions of the Convention and, in spite of a tenuous argument founded upon the third paragraph of art. 10, the intention is clear that the limitation provision was intended to be applicable to all claims for salvage.
Then, the argument proceeds, when one comes to consider S. 396 one sees that the legislature has, in one sub-section, proceeded to implement the provisions of each convention, that is to say, to prescribe a period of limitation with respect to claims against ships and their owners in respect of damage done by one ship to another or to its cargo or persons on board and with respect to claims for salvage services. This method of approach, however, is not open, unless, considered by itself, S. 396 (1) is found to be reasonably susceptible of more than one meaning. If it is ambiguous it is, upon long-established authority, permissible to take these extraneous matters into consideration but if its language is appropriate to afford a measure of protection to shipowners only that must be the end of the matter.
The first thing that may be said about S. 396 is that, on its face, it is a section which deals with three categories of claims. These are claims in respect of damage done by one vessel to another or to its cargo or to persons on board, claims for salvage and claims for contribution under S. 261.
In substance these categories are quite distinct and different. Two of the categories are dealt with in sub-s. (1) which prescribes two years as the appropriate period of limitation, whilst the third category is dealt with in sub-s. (2) where the prescribed period is one year only. In passing it may, perhaps, be said that although S. 8 of the Maritime Conventions Act 1911 dealt with all three categories in one paragraph, it was found convenient in drafting S. 396 to deal separately with causes of action for which different periods of limitation were to be prescribed.
In approaching the construction of sub-s. (1) it is, I think, of importance to bear in mind that it deals with distinct categories of claims. That is to say it deals with claims in respect of loss or
