This contribution discusses the Iraq War of 2003. It begins by setting out the facts and context of the US and British invasion. It then considers the legal justifications put forward by the intervening states and assesses the reaction of the international community to these events. It then tests the legality of the intervention against the international legal framework governing the use of force as it stood at the time of the events. In particular it considers whether UNSC Resolution 1441 provided a legal basis for the use of force against Iraq. The final section examines if, and to what extent, the case had an impact on the further development of the jus ad bellum. The Iraq War of 2003 did indeed have an effect on the erosion of the prohibition of the use of force, however it was a cumulative effect, rather than an immediate and decisive one.
