In early January 2015 the Republic of South Korea sold 1.9 million tear gas canisters to Turkey. With this sale came much campaigning against it. Amnesty International’s “Korea, do not sell us tear gas” campaign received over 50,000 signatures of support. The goal of this campaign was to highlight how the Turkish police force has been and continues to be to this day reckless and excessive in its use of tear gas on certain domestic demonstrations. Reckless and excessive use which, according to data collected by the Turkey Human Rights Joint Platform, led to the death of 19 Turkish citizens between 2006 and 2013 — including four children.
The sale of such large quantities of tear gas to a country that has a proven track record of using it frequently and recklessly raises important questions of international law. It raises questions in particular with regard to the responsibility of third states for internationally wrongful acts and the standard of proof required to establish such responsibility. Put simply, did South Korea commit an internationally wrongful act when it sold tear gas to Turkey?
Tear gas and international law
The name tear gas encompasses a group of substances that irritate mucous membranes and cause stinging sensations and tears. The effect of tear gas is normally considered temporary for a healthy adult so long as they are able to breathe fresh air shortly after exposure. Fatalities have been caused when tear gas has been used in closed spaces, on unhealthy adults or the elderly, or when canisters have been fired directly at protesters.
The use of tear gas is prohibited in wartime both by the 1925 Gas Protocol and the 1993 Chemical Weapons Convention. The 1993 Convention, however, explicitly includes a clause in Article 1(5), inserted at the insistence of the United States, stating that “Each State Party undertakes not to use riot control agents as a method of warfare.” Article II(7) of the 1993 Convention further defines a “Riot Control Agent” as “Any chemical not listed in a Schedule, which can produce rapidly in humans sensory irritation or disabling physical effects which disappear within a short time following termination of exposure.” This clause, by implication, signals a regime of permissibility for riot control agents — including tear gas — during peacetime.
