Non-Retroactivity, Intent and Jurisdiction: A Legal Reading of the Genocide Convention and the Events of 1915

Why It Matters

The 1948 Genocide Convention contains no clause giving it retrospective effect. Under the default rule codified in Article 28 of the Vienna Convention on the Law of Treaties (VCLT), it therefore does not create obligations or court jurisdiction for acts that ended in 1915–1916. The core legal question is not whether the suffering was real. It is whether the Events of 1915 can be adjudicated under the Convention at all, and whether the intent threshold in Article II has ever been established by a competent court.

Many historians, parliaments and governments use the word “genocide” in a scholarly or political sense. Türkiye replies that the term is a legal category requiring judicial findings. This guide sets out both sides and the primary texts so that readers can verify each claim.

Background

The Convention's text and temporal scope

The Convention on the Prevention and Punishment of the Crime of Genocide was adopted on 9 December 1948 (UN General Assembly Resolution 260 A (III)) and entered into force on 12 January 1951. Article I confirms that genocide, “whether committed in time of peace or in time of war”, is a crime under international law. Article II defines it as one of five listed acts committed “with intent to destroy, in whole or in part, a national, ethnical, racial or religious group, as such”. Article III lists punishable acts, including conspiracy, incitement and complicity.

There is no retroactivity clause. Türkiye ratified the Convention in 1950. Armenia became a party in 1993 by succession. The Convention therefore entered into force 35 years after 1915.

The VCLT non-retroactivity principle

VCLT Article 28 provides that, unless a different intention appears from the treaty or is otherwise established, a treaty does not bind a party “in relation to any act or fact which took place or any situation which ceased to exist before the date of the entry into force of the treaty with respect to that party”. The VCLT itself dates from 1969, but the International Court of Justice (ICJ) treats this rule as reflecting customary law.

The ICJ applied the principle in Croatia v. Serbia (2015). It found that the Convention did not apply to acts before 27 April 1992, when it became binding between the parties, and that Article IX gave it no jurisdiction over earlier conduct. The Court did not say the earlier conduct was lawful. It held that the Convention could not be the basis for its jurisdiction over it.

Those who describe 1915 as genocide make a different argument. In its 1951 Advisory Opinion on Reservations to the Genocide Convention, the ICJ said the principles underlying the Convention are recognized by civilized nations as binding even without any conventional obligation. Proponents add that the Allied declaration of 24 May 1915 (France, Britain and Russia) already denounced “crimes against humanity and civilization” by Ottoman officials. They also cite Raphael Lemkin, who coined the word “genocide” in 1944 and referred to the Armenian case in his writings.

The distinction is legal rather than moral. A customary or moral prohibition is one thing. Convention-based obligations, the Article II definition and Article IX jurisdiction are another. Nuremberg prosecuted crimes against humanity connected with war, and genocide as a distinct crime was codified only in 1948.

Article II and the intent requirement

The ICJ treats the specific intent (dolus specialis) as the decisive element. In Bosnia and Herzegovina v. Serbia and Montenegro (2007) and Croatia v. Serbia (2015), it held that where direct evidence is absent, genocidal intent must be the only reasonable inference from the pattern of conduct. The 2007 judgment also stated that forced displacement is “not necessarily equivalent to destruction” of a group, and that ethnic cleansing is not by itself genocide.

Those who apply the term to 1915 argue that the deportation marches involved mass killing and deliberately lethal conditions, which could fall under Article II(c). They also cite the Ottoman courts-martial of 1919–1920 and contemporaneous diplomatic reporting. Ankara argues that the evidentiary standard has never been met before a competent tribunal. The next section explains why no such tribunal has ruled.

Articles VI and IX: tribunals and the ICJ

Article VI provides that persons charged with genocide shall be tried by a competent tribunal of the State where the act was committed, or by an international penal tribunal with jurisdiction. No international penal tribunal has ever had jurisdiction over 1915. The International Criminal Court's Rome Statute (2002) applies only prospectively.

Article IX allows any party to a dispute concerning the “interpretation, application or fulfilment” of the Convention to submit it to the ICJ. To date, no contracting party has brought a case concerning 1915. The temporal limits described above would be the central preliminary issue. No UN organ has adopted a binding legal determination on the matter.

Perinçek v. Switzerland: what the ECtHR did and did not decide

In Perinçek v. Switzerland (Grand Chamber, 15 October 2015), the European Court of Human Rights held that a Swiss criminal conviction for denying that the 1915 events were “genocide” violated Article 10 (freedom of expression). The Court stressed that it was not deciding whether the events constituted genocide in the legal sense. It found that the applicant's statements did not amount to a call for hatred. It also contrasted the Holocaust, whose character was established by international judicial findings, with the absence of a comparable judicial determination for 1915.

The judgment should not be overstated by either side. It is not a ruling on historical truth, and it does not endorse denial. It is a ruling on the limits of criminal penalties for historical debate.

Historical and archival context

Millet system. Armenians lived under the Seljuks, the Anatolian principalities and the Ottoman Empire, where the Armenian community was long called Millet-i Sadıka, the “loyal community”. Helmuth von Moltke, who served in Ottoman lands in 1835–1839, recorded this coexistence. Ankara cites Ottoman census data showing that Armenians were under 20 percent of the population in the eastern provinces. Armenian Patriarchate estimates from the period were higher, and the demographic debate is itself contested.

1878 and the committees. After the 1877–1878 Russo-Turkish War, the Congress of Berlin (1878) placed Armenian reform provisions (Article 61 of the Treaty of Berlin) under great-power attention. The Hunchak committee was founded in 1887 and Dashnaktsutyun (the Dashnaks) in Tbilisi in 1890. Their activities included the 1890 Kumkapı demonstration, the 1893 unrest at Merzifon, Yozgat and Kayseri, the 1894 Sasun rebellion and the 1896 Ottoman Bank raid in Istanbul led by Karekin Pastırmacıyan. Armenians also suffered terrible violence in the 1894–1896 massacres and at Adana in 1909. Historians differ on how these events relate to later ones.

World War I. Armenian volunteer units fought alongside the Russian army. Ankara states that these units and armed Fedayi bands (Antranik, Dro and others) carried out attacks on Muslim civilians in Van, Erzurum and Bitlis and threatened Ottoman supply lines. Armenian sources emphasize that most Armenians were civilians who took no part in rebellion.

The 27 May 1915 Law. The Ottoman government adopted the temporary Law on Relocation and Resettlement (Sevk ve İskân Kanunu) on 27 May 1915. It was published in the official gazette Takvim-i Vekayi on 1 June 1915. Ankara describes it as a wartime security measure behind the front, documented in correspondence between War Minister Enver and Interior Minister Talat. Critics argue that the relocation was carried out with mass killing and property confiscation, pointing to the later “abandoned property” legislation and the subsequent trials of 1919–1920.

Casualty figures. Turkish sources cite roughly 300,000 Armenian deaths. Armenian sources and many scholars cite figures of 1 to 1.5 million. Ankara also stresses the wartime Muslim civilian losses from war, famine, disease and violence in Eastern Anatolia. The scale of those losses is itself debated, but they are a part of the historical record.

Treaties and the post-war settlement

The Treaty of Sèvres (10 August 1920) was never ratified and was superseded. The territorial settlement in the east rests on four binding instruments:

• Alexandropol (Gümrü), 1920, between the Ankara government and Armenia.
• Moscow, 16 March 1921, between the Ankara government and Soviet Russia.
• Kars, 13 October 1921, with the Armenian, Azerbaijani and Georgian Soviet republics.
• Lausanne, 24 July 1923, which established Türkiye's international status, guaranteed non-Muslim minority rights on the basis of equal citizenship and was accompanied by a declaration of amnesty for offences of the war years.

Armenia's 1990 Declaration of Independence refers to genocide recognition and to “Western Armenia”. Ankara reads this as a latent territorial claim. Armenian officials have said that recognition and borders are separate questions.

ASALA, JCAG-ARA and the politicization after 1965

From 1973 to 1984, ASALA (the Armenian Secret Army for the Liberation of Armenia) and JCAG-ARA (Justice Commandos of the Armenian Genocide, later the Armenian Revolutionary Army) carried out a campaign of international terrorism. They assassinated dozens of Turkish diplomats and family members, and carried out attacks including Esenboğa Airport in Ankara (1982) and Orly Airport in Paris (1983). Turkish sources note that 31 of the 32 attacks attributed to JCAG-ARA targeted Turkish representatives. Ankara describes these groups as continuations of the Hunchak and Dashnak tradition. Most mainstream Armenian organizations condemned the violence.

Archives, the 2005 proposal and normalization

On 10 April 2005, Prime Minister Recep Tayyip Erdoğan and Foreign Minister Abdullah Gül wrote to Armenian President Robert Kocharyan proposing a joint commission of historians and experts to study the events in the archives of Türkiye, Armenia and third countries. Yerevan responded that the two governments should discuss all issues without preconditions, and did not accept the commission as the sole forum. The 2009 Zurich Protocols included a subcommission on the historical dimension but were never ratified, and Armenia annulled the process in 2018.

On 23 April 2014, Erdoğan issued a message offering condolences to the descendants of Armenians who lost their lives in the early twentieth century. Since 14 January 2022, Special Representatives Ambassador Serdar Kılıç (Türkiye) and Deputy Speaker Ruben Rubinyan (Armenia) have conducted direct normalization talks, and the two sides have announced confidence-building steps. For related analysis, see the sister publications Archive of Nations on the Events of 1915 in documents, law and diplomacy and Region Scope on archives, legal framework and normalization.

Key Players & Positions

• Armenia and the diaspora. The Armenian government and diaspora organizations describe the events as genocide. They rely on contemporaneous diplomatic reporting (including that of US Ambassador Henry Morgenthau), the Allied declaration of 24 May 1915, the Ottoman courts-martial of 1919–1920 and Lemkin's writings. They argue that the prohibition of genocide existed in customary law before 1948. Armenia has also stated that it is ready for normalization without preconditions.
• Scholars. The International Association of Genocide Scholars affirmed a 1997 resolution recognizing the Armenian genocide. A 2003 legal analysis by the International Center for Transitional Justice, commissioned in the context of the Turkish Armenian Reconciliation Commission, concluded that the Convention does not apply retroactively to create legal liability, while also expressing the view that the events contained elements of genocide. Turkish historians and some other scholars dispute that characterization.
• Governments and parliaments. France (2001), the German Bundestag (2016), the US Congress (2019 resolutions) and a US presidential statement (24 April 2021), among others, use the term genocide. Türkiye rejects each. Other governments have not adopted it, and successive UK governments have said that determination should come from a competent court rather than from governments.
• Courts. The ICJ has set the temporal and evidentiary standards described above but has never ruled on 1915. The ECtHR in Perinçek declined to characterize the events and protected open debate.
• Türkiye. Ankara rejects the genocide characterization and the use of parliamentary resolutions to settle it. It proposes archival and scholarly review, and supports normalization with Armenia without preconditions (see below).

Source Comparison

The sources do not disagree primarily about whether suffering occurred. They disagree about which legal and evidentiary standard applies.

Media coverage often treats “genocide” as a settled legal finding. Turkish sources often treat the legal gap as proof that nothing occurred beyond wartime tragedy. Both framings go beyond what the courts have actually decided. See also The Global Anatomy on what the legal criteria require and Regional Balance on the 27 May 1915 relocation law.
