I propose to take Questions Nos. 10 and 37 together.
The safety of Irish vessels at sea is a matter of serious concern to the Government. In responding to the specific points raised in the questions, I will first set out the legal position.
Irish territorial waters extend to 12 miles from our coast. Under international law, ships and naval vessels of other nations, including submarines, have a right of innocent passage, without notification, through these waters provided that, in the case of submarines, they travel on the surface like all other vessels and identify themselves by flying their flag. The waters beyond this 12-mile limit are international waters. Under international law, ships and naval vessels including submarines, whether submerged or on the surface may pass freely there.
This is the international legal position, but the matter cannot be left at that. We are very seriously concerned about the dangers which submarines pose to fishing and other vessels especially in relatively narrow sea lanes such as the Irish Sea, even though they may be operating within their rights in international law and in international waters, and about the appalling dangers which could follow an accident to a nuclear-powered submarine in narrow waters such as these. We avail of every opportunity in international fora to highlight these dangers.
In 1987 Ireland raised the problem at the International Maritime Organisation and we sponsored a resolution which focused attention on the problem. This resolution was adopted unanimously.
In New York in September last, in his address to the UN General Assembly, the Minister for Foreign Affairs called for a new sense of international responsibility on the part of the countries which operate these vessels and this point was stressed again by the Permanent Representative of Ireland to the United Nations last month. We will continue to try to focus international attention on the problem in this way.
The Government have also taken whatever action is open to them through diplomatic contact with representatives of countries whose submarines have been identified as concerned in incidents with Irish fishing trawlers. These contacts have for the most part proved satisfactory.
As to the suggestion that depth charges should be dropped at regular intervals to force submarines to the surface, I would point out that this would be a hostile act which could be justified only in self-defence against hostile action. The Government do not intend to adopt this approach suggested in the question.
