Practical experience may well disprove some of what I am saying, but there are a number of registering authorities. The first thing to determine is whether a vessel is registered with Bureau Veritas, Lloyds or whoever, and it might not be registered at all. I know from experience that this is not quick or easy to determine. The same name may be used on more than one ship. As I argued earlier, it is desirable that the power to arrest should not be subject to that procedure. The Minister of State may well point out that we cannot do that under the international law of the sea. If the argument is considered to be of merit, perhaps we should make approaches to see if we can get changes in the law in this regard.
