On March 31, 2014, the International Court of Justice (ICJ) issued its judgment in the case of Whaling in the Antarctic (Australia v. Japan: New Zealand Intervening) (Whaling Decision). In what is perhaps its most important environmental decision to date, the ICJ ordered Japan to halt its whaling program in the Southern Ocean, finding the program lacked scientific merit and breached requirements of the International Convention for the Regulation of Whaling (ICRW).

In 2013, the International Court of Justice (ICJ) rendered judgment in a dispute between Cambodia and Thailand (the 2013 Judgment)1 over the interpretation of the ICJ’s previous decision in the Case Concerning the Temple of Preah Vihear (the 1962 Judgment).2 The parties’ dispute arises from longstanding uncertainty over the location of the territorial boundary between Cambodia and Thailand in the region of the Dangrek Mountains. Neither the original judgment nor its interpretation fully resolves this uncertainty, although together they confirm Cambodia’s sovereignty over the Temple of Preah Vihear and the high promontory on which it stands.

On September 16, 2014, the Grand Chamber of the European Court of Human Rights (the Court) gave its judgment in the case of Hassan v. United Kingdom.This is the Court’s first explicit engagement with the co-applicability of international humanitarian law and international human rights law in relation to detention in international armed conflicts. The judgment is significant for its rejection of the government’s argument that international humanitarian law operates as lex specialis to displace international human rights law entirely during the “active hostilities phase of an international armed conflict.” It is also noteworthy for the majority’s ruling that provisions on detention of prisoners of war and the internment of protected persons in the Third and Fourth Geneva Conventions of 1949 could be read into Article 5 (right to liberty and security) of the European Convention on Human Rights (the European Convention), creating a new ground for detention under Article 5(1) in international armed conflicts and modifying the procedural guarantees in Article 5(4).

On March 5, 2014, the Supreme Court of the United States (the Court or Supreme Court) rendered its decision in BG Group PLC v. Republic of Argentina (BG Group). Applying principles from judicial review of commercial arbitration awards to the investment treaty context, the Court overturned a decision of the United States Court of Appeals that vacated an investment treaty arbitral award. BG Group is significant because it is the first time that the Supreme Court has reviewed an investment treaty arbitration.

On November 27, 2013, the Supreme Court of Appeal (SCA) handed down a judgment on an appeal from the South African Police Service and Prosecution Authority in National Commissioner of the South African Police Service v. Southern African Human Rights Litigation Centre (the Decision). The Court decided that the South African Police Service is empowered to initiate investigations into alleged crimes against humanity committed in the territory of another state, irrespective of whether the alleged perpetrators are present in South Africa, and ordered the authorities to initiate such investigations.
