Article 6 of the Geneva Convention of 1958 on the Continental Shelf
2. Where the same continental shelf is adjacent to the territories of two adjacent States, the boundary of the continental shelf shall be determined by agreement between them. In the absence of agreement, and unless another boundary line is justified by special circumstances, the boundary shall be determined by application of the principle of equidistance from the nearest points of the baselines from which the breadth of the territorial sea of each State is measured. 3. In delimiting the boundaries of the continental shelf, any lines which are drawn in accordance with the principles set out in paragraphs 1 and 2 of this article should be defined with reference to charts and geographical features as they exist at a particular date, and reference should be made to fixed permanent identifiable points on the land.

The questions at hand
Netherlands and Denmark argued that the rights of the coastal State to its continental shelf areas were based on its sovereignty over the land domain, of which the shelf area was the natural prolongation under the sea. The Court accepted this view. Denmark and the Netherlands further argued that this domain can only be measured by proximity. As only an equidistance line would do this, the rule should be applied.
Though the Court agreed that most of the continental shelf areas of a State are usually nearer to its coast than of any other state, it did not agree on the notion that every part of the area concerned should be delimited that way. Submarine areas do not appertain to a coastal state merely because they are near it nor does their delimitation necessarily depend on their boundaries. The ipso jure title to submarine areas belongs to the state of which land area the submarine area is a natural prolongation of. The use of the equidistance rule would often cause situations where the natural prolongation of a state would be attributed to another. Thus, the rule is not an a priori accompaniment of basic continental shelf doctrine.

According to "Truman Proclamation" issued by the Government of the United States on 28 September 1945 the coastal State had an original, natural and exclusive right to the continental shelf off its shores. This view was also reflected in the 1958 Geneva Convention. Both the Truman Proclamation and the 1958 Geneva Convention put emphasis on the concepts of mutual agreement and equitable principles. The Court speculated that the equidistance rule was added to the Convention by the International Law Commission for purposes of practical convenience and cartography. Moreover, the article contains an exception to the rule in favor of special circumstances.
The principle of equidistance had not been proposed by the International Law Commission as an emerging rule of customary international law nor did it reflect or crystallize such a rule.
Any State could make reservations to Article 6, unlike to some of the other more binding articles on signing, ratifying or acceding to the Convention. since it was not excluded from the faculty of reservation, it was a legitimate inference that it was not considered to reflect emergent customary law.
No other article in the convention supports the binding nature of Article 6.
The Netherlands and Denmark argued that such a rule had come into being since the Convention in part because of its own impact, and additionally on the basis of subsequent State practice.
For this to occur, Article 6 should be of a norm creating character. However, the primary obligation found in Article 6 is delimitation by agreement. Further, the exception to the equidistance rule and the possibility of making reservations raise doubts to norm-creating character of the article.
The number of ratifications and accessions so far is hardly sufficient to create a customary rule of international law in and of itself. With regards to state practise, this rule should have been extensive and virtually uniformly invoked in such a way as to show a general recognition that a rule of law was involved. The 15 cited cases where states had drawn the boundaries according to the principle of equidistance, but there is no evidence to support the notion that they felt legally compelled to do so.

Ex aequo et bono - "according to the right and good"
The parties were to conduct themselves so that the following negotiations would be meaningful and be willing to contemplate modifications to their own positions as stated in Article 33 of the Charter of the UN. Equitable principles were to be applied. The following factors should be taken into account:
The general configuration of the coasts of the Parties, as well as the presence of any special or unusual features
The physical and geological structure and natural resources of the continental shelf areas involved
The element of a reasonable degree of proportionality between the extent of the continental shelf areas appertaining to each State and the length of its coast measured in the general direction of the coastline, taking into account the effects, actual or prospective, of any other continental shelf delimitations in the same region.
