Decisions of international courts and arbitrators, as well as judgments of national courts, are fundamental elements of modern public international law. The International Law Reports is the only publication in the world wholly devoted to the regular and systematic reporting in English of such decisions. It is therefore an absolutely essential work of reference. Volume 169 reports on, amongst others, the 2015 Arbitration Award on Jurisdiction and Admissibility in Philip Morris Asia Limited v. Commonwealth of Australia, the 2012 judgment of International Court of Justice in Territorial and Maritime Dispute (Nicaragua v. Colombia) and the 2014 and 2015 Canadian judgments of Supreme Court and Court of Appeal of British Columbia in United Mexican States v. British Columbia (Labour Relations Board) regarding State immunity.
