I agree with the Court’s conclusion that the information available does not appear to establish that the delimitation of a maritime boundary by a loxodrome line on a standard navigational chart based on Mercator projection without correction for scale error is either inadmissible in law or so outmoded in practice as to make its use open, in general, to challenge. It is necessary, on the other hand, to consider the possible impact in this connexion of the great extension seawards of the boundary in the present case, combined with the lateral relation of the coasts of the United Kingdom and France in the Atlantic region. The Court, as it has recognized, made this combination of circumstances one of the cardinal elements in its decision to allow only half-effect to the Scilly Isles. Expressing its conclusions on this point in paragraph 242 of the Decision of 30 June 1977, the Court said:
What is important is that, in appreciating the appropriateness of the equidistance method as a means of effecting a "just" or "equitable" delimitation in the Atlantic region. the Court must have regard both to the lateral relation of the two coasts as they abut upon the continental shelf of the region and to the great distance seawards that this shelf extends from those coasts.
