San Remo Manual The San Remo Manual is a 1994 non-binding expert consensus document setting out customary and conventional norms for naval warfare, compiled at a conference in Sanremo. It synthesizes practices related to maritime blockades, neutral shipping, and weapons use, drawing on precedents from the Hague Conventions, Geneva Conventions, United Nations Charter, and customary law as reflected in rulings of the International Court of Justice, decisions from the International Criminal Tribunal for the former Yugoslavia, and state practice of navies such as the Royal Navy, United States Navy, and Russian Navy. The Manual has been cited in debates involving incidents like the Falklands War, the Gulf War, and operations off Somalia.

Background and Development

The Manual was drafted by an International Group of Experts convened under the auspices of scholars and practitioners from institutions including the International Committee of the Red Cross, the NATO Shipping Centre, the University of Oxford, the Harvard Law School, and the United Nations's legal community. Its genesis drew on state practice during conflicts such as the First World War, the Second World War, the Korean War, the Vietnam War, and the Yom Kippur War, and on jurisprudence from the International Criminal Tribunal for Rwanda and advisory opinions of the International Court of Justice. Contributors included former officers and academics linked to the Royal Australian Navy, French Navy, German Navy, and legal advisers from the US Department of Defense. The conference at Sanremo produced a draft intended for use by commanders, legal advisers, and scholars in navies, coast guards, and port authorities such as those in Italy, United Kingdom, United States, and Japan.

Scope and Legal Basis

The Manual frames its rules by reference to treaties like the Hague Convention (XIII) (1907), the Hague Regulations, and the four Geneva Conventions while acknowledging the primacy of the United Nations Charter. It addresses questions of belligerent rights and neutral duties found in precedents including the Declaration of London and state practices from the Blockade of Germany (1914–1919). The drafters relied on decisions and writings from the International Law Commission, opinions by the United States Solicitor General, and manuals such as the British Manual of Naval Law. The Manual explicitly situates itself as reflecting customary international law applicable to naval operations, with attention to maritime zones defined in instruments like the United Nations Convention on the Law of the Sea.

Key Provisions and Rules

The Manual articulates rules on belligerent conduct including principles for declaring and enforcing a blockade, intercepting neutral shipping, requisitioning merchant vessels, and the use of force at sea. It sets out criteria for distinguishing combatants linked to historical practice in the Napoleonic Wars and contemporary doctrine used by the United States Navy and NATO forces. Provisions address the protection of prisoners and wounded informed by the Geneva Conventions, constraints on weapons echoing standards from the Chemical Weapons Convention and rulings of the International Criminal Court, and rules for mine warfare reflecting practices from the Baltic Sea conflicts and the Persian Gulf. The Manual explains procedures for adversary communications, capture and detention comparable to protocols in the Yalta Conference agreements on repatriation, and safeguards for neutral flags as debated after incidents like the Trent Affair.

Interpretation and Application

States, navies, and tribunals have treated the Manual as authoritative guidance rather than binding law; courts such as the International Court of Justice and tribunals like the International Criminal Tribunal for the former Yugoslavia have considered similar norms in adjudication. Operational legal advisers from the United States Department of Defense, Royal Australian Navy, and NATO have used the Manual to craft rules of engagement during crises involving actors such as Somali pirates, Iran, and non-state groups tied to Hezbollah. Scholars at institutions including Cambridge University, the London School of Economics, and the Max Planck Institute for Comparative Public Law and International Law have analyzed its provisions in relation to the United Nations Convention on the Law of the Sea and state practice in incidents like the Maersk Alabama seizure. The Manual’s language informs doctrinal publications from the US Pacific Fleet and legal training at academies like the US Naval War College.

Impact and Reception

The Manual has influenced naval doctrine, academic commentary, and intergovernmental discussions at forums such as the International Maritime Organization and United Nations General Assembly. Navies including the Royal Navy, United States Navy, French Navy, and Indian Navy reference its guidance in operational planning and manuals. Humanitarian organizations like the International Committee of the Red Cross and NGOs including Amnesty International and Human Rights Watch have cited the Manual when assessing harms in maritime operations. Its status as a distillation of customary practice has made it a point of reference in debates before bodies like the International Tribunal for the Law of the Sea.

Criticisms and Controversies

Critics argue the Manual’s non-binding character leaves gaps when applied to contemporary challenges posed by actors such as non-state armed groups, private military contractors linked to firms like Blackwater, and issues of cyber operations at sea discussed in forums including Tallinn Manual workshops. Some states including Russia and commentators from the Shanghai Cooperation Organisation caution that the Manual may reflect Western doctrinal priorities. Legal scholars from Yale Law School and Columbia Law School have questioned its treatment of neutrality, blockade legality, and obligations under the United Nations Convention on the Law of the Sea, while advocates from Amnesty International and Human Rights Watch have pressed for clearer protections for civilians in littoral operations. Debates persist in venues such as the International Law Commission and workshops at the Asil annual meeting.
