Abstract

The purpose of this article is to examine the key elements of the legal framework in which naval mines are used both across the spectrum of conflict and during peacetime. The article will also consider the legal issues associated with the use of mines by States in international armed conflict, and address the distinct legal issues which arise in non-international armed conflict, where the emergence of an increasing presence of non-State armed groups has been a hallmark of the late twentieth and early twenty-first centuries. The obligations placed upon States in peacetime, and under the law of neutrality, when the use and presence of naval mines is a relevant factor will also be analyzed.

In producing this article, the author obtained substantial benefit from his participation in a Workshop on Naval Mines which was organized by Chatham House, in association with the Royal Navy and US Naval War College, in February 2014. The output of fellow workshop participants, which appeared in International Law Studies, Vol. 90, 2014, has provided the author with a valuable resource upon which further research, and synthesis of some of the themes from the 2014 workshop, could be based.

2 The name “dreadnought” – “fear nothing” – refers to the first of a class of new ships that was built for the Royal Navy in the early 1900s. Subsequent fleets of battleships constructed by numerous navies derived from the dreadnought. The vessel which gave its name to this class of ships, HMS Dreadnought, was launched in 1906 and included revolutionary features for its time, such as vastly improved armour and greater numbers of large-calibre guns, as well as being powered by steam turbine. For a detailed analysis of the development, impact and characteristics of the dreadnought see Hough, Richard, Dreadnought: A History of the Modern Battleship, Periscope Publishing, Penzance, 2003Google Scholar.

3 During the era of the battleship, the size of projectile fired from the main armament steadily increased, with the largest gun types firing projectiles of 15-inch (381 mm), 16-inch (406.4 mm) and 18-inch (457.2 mm) calibre. In modern times, the main armament of a warship includes a variety of weapon systems, but the largest guns in regular use range between 3-inch (76.2 mm) and 5-inch (127 mm) calibre.

18 At the time, the weapons that are now known as “mines” were commonly referred to as “torpedoes” – hence the use of the latter term in the quote attributed to Farragut.

21 A recent example of the emphasis placed on the development of modern mine-clearance and warfare capabilities can be seen in the establishment of Australian Mine Warfare Team 16 by the Royal Australian Navy, which is intended to “deliver a sustainable, full-spectrum, deployable mine warfare capability to enable future expeditionary maritime task group operations”. See: news.navy.gov.au/en/Jul2016/Fleet/3079/New-mine-warfare-team-established.htm.

23 S. Haines, above note 17, p. 420.

24 Ibid. See also the San Remo Manual, above note 9, p. 168, where it is contended that at “the time the Convention was drafted, it was deplored that no absolute prohibition could be agreed upon”. See also Y. Dinstein and F. Domb (eds), above note 9, p. 375, where it is noted that “Great Britain had urged outlawing the use of automatic contact mines in open sea areas beyond the belligerents’ territorial waters” as a means of preserving its naval dominance, but this proposal was not supported as “the majority of States represented at The Hague … [were] … unwilling to refrain from the use of this most effective means of naval warfare”.

25 The title of Hague Convention VIII is “relative to the Laying of Automatic Submarine Contact Mines”, but the text of the Convention excludes the word “submarine” and refers only to “automatic contact mines”.

26 See, for example, the San Remo Manual, above note 9, p. 169, where it is noted that “practice by belligerents in the first Gulf War showed that the provisions of the Convention have continued validity in modern naval warfare”. The status of Hague Convention VIII as customary international law is left as an open question by A. Roberts and R. Guelff, above note 16, p. 103, who merely observe that “to the extent that any aspect of the Convention may be considered customary international law, such aspect would be applicable to all States and the Convention's ‘general participation clause’ (Article 7) would cease to be relevant in that regard”. Note also the quotation regarding the Soviet view of Hague Convention VIII in H. Levie, above note 16, p. 175, that “for all its weak points the VIII Hague Convention is regarded as customary international law of the sea”. Haines also considers that “the rules contained in the 1907 Convention are regarded as having attained customary status in relation to automatic contact mines alone”, and he observes that “when combined with other elements of customary law” the result was the production of the rules which are provided in the San Remo Manual: S. Haines, above note 17, p. 443.

27 The first seven articles of Hague Convention VIII are:

Article 1. It is forbidden:

  1. 1.

    1. To lay unanchored automatic contact mines, except when they are so constructed as to become harmless one hour at most after the person who laid them ceases to control them;

  2. 2.

    2. To lay anchored automatic contact mines which do not become harmless as soon as they have broken loose from their moorings;

  3. 3.

    3. To use torpedoes which do not become harmless when they have missed their mark.

Article 2. It is forbidden to lay automatic contact mines off the coast and ports of the enemy, with the sole object of intercepting commercial shipping.

Article 3. When anchored automatic contact mines are employed, every possible precaution must be taken for the security of peaceful shipping.

The belligerents undertake to do their utmost to render these mines harmless within a limited time, and, should they cease to be under surveillance, to notify the danger zones as soon as military exigencies permit, by a notice addressed to ship owners, which must also be communicated to the Governments through the diplomatic channel.

Article 4. Neutral Powers which lay automatic contact mines off their coasts must observe the same rules and take the same precautions as are imposed on belligerents.

The neutral Power must inform ship owners, by a notice issued in advance, where automatic contact mines have been laid. This notice must be communicated at once to the Governments through the diplomatic channel.

Article 5. At the close of the war, the Contracting Powers undertake to do their utmost to remove the mines which they have laid, each Power removing its own mines.

As regards anchored automatic contact mines laid by one of the belligerents off the coast of the other, their position must be notified to the other party by the Power which laid them, and each Power must proceed with the least possible delay to remove the mines in its own waters.

Article 6. The Contracting Powers which do not at present own perfected mines of the pattern contemplated in the present Convention, and which, consequently, could not at present carry out the rules laid down in Articles 1 and 3, undertake to convert the materiel of their mines as soon as possible, so as to bring it into conformity with the foregoing requirements.

Article 7. The provisions of the present Convention do not apply except between Contracting Powers, and then only if all the belligerents are parties to the Convention.

36 At the time, there was no codified agreement on the maximum breadth of a State's territorial waters, but there was wide acceptance of a maximum breadth of 3 nautical miles as a matter of customary international law. Codified agreement regarding the maximum breadth of the territorial sea (12 nautical miles) was finally reached with the entry into force of the United Nations Convention on the Law of the Sea, 1833 UNTS 3, 10 December 1982 (entered into force 16 November 1994) (UNCLOS).

45 The two main parties involved in the conflict were the Sandinistas, who came to power in Nicaragua at the conclusion of the revolution of 1978–79, and the contras, which is the generic name given to a number of groups which were attempting to overthrow the Nicaraguan government in the early 1980s. The contras received various types of support from the United States.

112 S. C.
