The International Court of Justice (commonly referred to as the World Court, is the primary judicial branch of the United Nations (UN). Seated in the Peace Palace in The Hague, Netherlands, the court settles legal disputes submitted to it by states and provides advisory opinions on legal questions submitted to it by duly authorized international branches, agencies, and the UN General Assembly.

The ICJ is composed of fifteen judges elected to nine-year terms by the UN General Assembly and the UN Security Council from a list of people nominated by the national groups in the Permanent Court of Arbitration. The election process is set out in Articles 4–19 of the ICJ statute. Elections are staggered, with five judges elected every three years to ensure continuity within the court. Should a judge die in office, the practice has generally been to elect a judge in a special election to complete the term.

Article 6 of the Statute provides that all judges should be "elected regardless of their nationality among persons of high moral character" who are either qualified for the highest judicial office in their home states or known as lawyers with sufficient competence in international law. Judges of the ICJ are not able to hold any other post or act as counsel. In practice, Members of the Court have their own interpretation of these rules and allow them to be involved in outside arbitration and hold professional posts as long as there is no conflict of interest.
