Hostis humani generis (Latin for 'an enemy of mankind') is a legal term of art that originates in admiralty law. Before the adoption of public international law, pirates and slavers were generally held to be beyond legal protection and so could be dealt with by any nation, even one that had not been directly attacked.
A comparison can be made between this concept and the common law "writ of outlawry", which declared a person outside the king's law, a literal out-law, subject to violence and execution by anyone. The ancient Roman civil law concept of proscription, and the status of homo sacer conveyed by proscription may also be similar. [1]
Perhaps the oldest of the laws of the sea is the prohibition of piracy, as the peril of being set upon by pirates, who are not motivated by national allegiance, is shared by the vessels and mariners of all nations, and thus represents a crime upon all nations. Since classical antiquity, pirates have been held to be individuals waging private warfare, a private campaign of sack and pillage, against not only their victims, but against all nations, and thus, those engaging in piracy hold the particular status of being regarded as hostis humani generis, the enemy of humanity. Since piracy anywhere is a peril to every mariner and ship everywhere, it is held to be the universal right and the universal duty of all nations, regardless of whether their ships have been beset by the particular band of pirates in question, to capture, try by a regularly constituted court-martial or admiralty court (in extreme circumstances, by means of a drumhead court-martial convened by the officers of the capturing ship), and, if found guilty, to execute the pirate via means of hanging from the yard-arm of the capturing ship, an authoritative custom of the sea. [2]
Although summary battlefield punishment was conducted by certain nations at certain times with regard to pirates, it was regarded as irregular (but lawful if the attenuation of due process was dictated by urgent military necessity), as individuals captured with pirates could potentially have a defense to charges of piracy, such as coercion. [3] For instance, in early 1831, the 250-strong crew captured off Ascension was brought to Ascension and summarily hanged, as they were acting in a rebellious manner and threatening to overthrow the 30-man crew of HMS Falcon, a British sloop-of-war, which took them captive. As the summary punishment, in this case, was due to military necessity, there was clear evidence of the offense, and it was done proximate in time and location to the battlefield, it can be classified as merely irregular, and not a violation of the custom of the sea. [3]
The land and airborne analogues of pirates, bandits and hijackers are not subject to universal jurisdiction in the same way as piracy; this is despite arguments [4] that they should be.[ citation needed ] Instead these crimes, along with terrorism, torture, crimes against internationally protected persons [5] and the financing of terrorism are subject to the aut dedere aut judicare principle (meaning prosecute or extradite). In the current global climate of international terrorism some commentators have called for terrorists of all sorts to be treated hostis humani generis. [6]
Other commentators, such as John Yoo, [7] have called for the extension of this hypothetical connection of hostis humani generis from pirates to hijackers to terrorists all the way to that of "unlawful enemy combatants". Unlawful enemy combatants, or persons captured in war who do not fight on behalf of a recognized sovereign state, have become an increasingly common phenomenon in contemporary wars[ dubious ], such as the War in Afghanistan, Iraq War, Chechen Wars and Syrian Civil War.
The only actual extension of hostis humani generis blessed by courts of law has been its extension to torturers. This has been done by decisions of U.S. and international courts; specifically, in a case tried in the United States in 1980, Filártiga v. Peña-Irala , 630 F.2d 876, the United States 2nd Circuit Court ruled that it could exercise jurisdiction over agents of the Alfredo Stroessner military dictatorship of Paraguay (in their individual capacity [8] ) who were found to have committed the crime of torture against a Paraguayan citizen, using its jurisdiction under the Offenses Clause [9] of the Constitution of the United States, the Alien Tort Claims Act, and customary international law. In deciding this, the court famously stated that "Indeed, for purposes of civil liability, the torturer has become like the pirate and slave trader before him: hostis humani generis, an enemy of all mankind." This usage of the term hostis humani generis has been reinforced by the ruling of the International Criminal Tribunal for the Former Yugoslavia in the conviction of a torturer in Prosecutor v. Furundžija. [10] [11]
In the Eichmann trial of 1961, the Jerusalem District Court did not explicitly deem Adolf Eichmann a hostis humani generis. The prosecution, however, invoked the standard, ultimately cited in the verdict by reference to piracy. [12] [13]
Jurisdiction is the legal term for the legal authority granted to a legal entity to enact justice. In federations like the United States, the concept of jurisdiction applies at multiple levels.
Universal jurisdiction is a legal principle that allows states or international organizations to claim criminal jurisdiction over an accused person regardless of where the alleged crime was committed, and regardless of the accused's nationality, country of residence, or any other relation to the prosecuting entity. Crimes prosecuted under universal jurisdiction are considered crimes against all, too serious to tolerate jurisdictional arbitrage. The concept of universal jurisdiction is therefore closely linked to the idea that some international norms are erga omnes, or owed to the entire world community, as well as to the concept of jus cogens – that certain international law obligations are binding on all states.
Piracy is an act of robbery or criminal violence by ship or boat-borne attackers upon another ship or a coastal area, typically with the goal of stealing cargo and other valuable goods. Those who conduct acts of piracy are called pirates, and vessels used for piracy are called pirate ships. The earliest documented instances of piracy were in the 14th century BC, when the Sea Peoples, a group of ocean raiders, attacked the ships of the Aegean and Mediterranean civilisations. Narrow channels which funnel shipping into predictable routes have long created opportunities for piracy, as well as for privateering and commerce raiding.
An unlawful combatant, illegal combatant or unprivileged combatant/belligerent is a person who directly engages in armed conflict in violation of the laws of war and therefore is claimed not to be protected by the Geneva Conventions. The International Committee of the Red Cross points out that the terms "unlawful combatant", "illegal combatant" or "unprivileged combatant/belligerent" are not defined in any international agreements. While the concept of an unlawful combatant is included in the Third Geneva Convention, the phrase itself does not appear in the document. Article 4 of the Third Geneva Convention does describe categories under which a person may be entitled to prisoner of war status. There are other international treaties that deny lawful combatant status for mercenaries and children.
The Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment is an international human rights treaty under the review of the United Nations that aims to prevent torture and other acts of cruel, inhuman, or degrading treatment or punishment around the world.
In an extradition, one jurisdiction delivers a person accused or convicted of committing a crime in another jurisdiction, over to the other's law enforcement. It is a cooperative law enforcement procedure between the two jurisdictions and depends on the arrangements made between them. In addition to legal aspects of the process, extradition also involves the physical transfer of custody of the person being extradited to the legal authority of the requesting jurisdiction.
Extraterritorial jurisdiction (ETJ) is the legal ability of a government to exercise authority beyond its normal boundaries.
A peremptory norm is a fundamental principle of international law that is accepted by the international community of states as a norm from which no derogation is permitted.
Filártiga v. Peña-Irala, 630 F.2d 876, was a landmark case in United States and international law. It set the precedent for United States federal courts to punish non-American citizens for tortious acts committed outside the United States that were in violation of public international law or any treaties to which the United States is a party. It thus extends the jurisdiction of United States courts to tortious acts committed around the world. The case was decided by a panel of judges from the United States Court of Appeals for the Second Circuit consisting of judges Wilfred Feinberg, Irving Kaufman, and Amalya Lyle Kearse.
Anti-terrorism legislation are laws with the purpose of fighting terrorism. They usually, if not always, follow specific bombings or assassinations. Anti-terrorism legislation usually includes specific amendments allowing the state to bypass its own legislation when fighting terrorism-related crimes, under alleged grounds of necessity.
Piracy in the Gulf of Guinea affects a number of countries in West Africa as well as the wider international community. By 2011, it had become an issue of global concern. Pirates in the Gulf of Guinea are often part of heavily armed criminal enterprises, who employ violent methods to steal oil cargo. In 2012, the International Maritime Bureau, Oceans Beyond Piracy and the Maritime Piracy Humanitarian Response Program reported that the number of vessels attacks by West African pirates had reached a world high, with 966 seafarers attacked during the year. According to the Control Risks Group, pirate attacks in the Gulf of Guinea had by mid-November 2013 maintained a steady level of around 100 attempted hijackings in the year, a close second behind the Strait of Malacca in Southeast Asia. Piracy in the Gulf of Guinea continues to be a concern to significantly affect the shipping industry, surging again in the 2020s. Governments in the region generally highlight that the fight against piracy requires a broad understanding of maritime security throughout the Gulf of Guinea.
Sosa v. Alvarez-Machain, 542 U.S. 692 (2004), was a United States Supreme Court case involving the Alien Tort Statute and the Federal Tort Claims Act. Many ATS claims were filed after the Second Circuit ruling in Filártiga v. Peña-Irala created a new common law cause of action for torture under the ATS: "For purposes of civil liability, the torturer has become—like the pirate and slave trader before him—hostis humani generis, an enemy of all mankind." The Court in Sosa does not find there is a similar cause of action for arbitrary arrest and detention. They wrote that finding new common law causes of action based on international norms would require "a substantial element of discretionary judgment", and explain that the role of common law has changed since ATS was enacted meaning the Court will "look for legislative guidance before exercising innovative authority over substantive law".
In law, the principle of aut dedere aut judicare refers to the legal obligation of states under public international law to prosecute persons who commit serious international crimes where no other state has requested extradition. However, the Lockerbie case demonstrated that the requirement to extradite or prosecute is not a rule of customary international law. The obligation arises regardless of the extraterritorial nature of the crime and regardless of the fact that the perpetrator and victim may be of alien nationality. It is generally included as part of international treaties dealing with an array of transnational crimes to facilitate bringing perpetrators to justice.
The Atlantic World refers to the period between European colonisation of the Americas (1492-) and the early nineteenth century. Piracy became prevalent in this era because of the difficulty of policing this vast area, the limited state control over many parts of the coast and the competition between different European powers. The best known pirates of this era are the Golden Age pirates (c.1650-1730) who roamed the seas off the coast of North America, Africa and the Caribbean.
Kiobel v. Royal Dutch Petroleum Co., 569 U.S. 108 (2013), was a United States Supreme Court decision in which the court found that the presumption against extraterritoriality applies to claims under the Alien Tort Claims Act. According to the Court's majority opinion, "it would reach too far to say that mere corporate presence suffices" to displace the presumption against extraterritoriality when all the alleged wrongful conduct takes place outside the United States.
The Hague Hijacking Convention is a multilateral treaty by which states agree to prohibit and punish aircraft hijacking. The convention does not apply to customs, law enforcement or military aircraft, thus it applies exclusively to civilian aircraft. The convention only addresses situations in which an aircraft takes off or lands in a place different from its country of registration. The convention sets out the principle of aut dedere aut judicare—that a party to the treaty must prosecute an aircraft hijacker if no other state requests his or her extradition for prosecution of the same crime.
The Protection of Diplomats Convention is a United Nations anti-terrorism treaty that codifies some of the traditional principles on the necessity of protecting diplomats.
The Convention for the Suppression of Unlawful Acts against the Safety of Civil Aviation is a multilateral treaty by which states agree to prohibit and punish behaviour which may threaten the safety of civil aviation.
Ye Banished Privateers are a folk rock band from Umeå, Sweden.
International piracy law is international law that is meant to protect against piracy. Throughout history and legal precedents, pirates have been defined as hostis humani generis, Latin for "the enemy of all mankind". The United Nations has codified much of the law in the United Nations Convention on the Law of the Sea (UNCLOS), which defines different types of piracy and ways to combat it.
