Chapter 6 analyses how legal procedures were included in the Paris Peace Treaties in order to solve one of the most sensitive and politically controversial questions of the post-war order: the payment of reparations from former Central Power governments or individuals to Allied individuals. In accordance with the peace treaties, 39 Mixed Arbitral Tribunals were established after 1920 to decide on private Allied claims for damages that had occurred during the war due to acts by former Central Power governments or individuals. The fact that an international court system permitted private individuals to raise claims against foreign governments was seen as a radical novelty; and even more so since tens of thousands of claimants throughout Europe and beyond attempted to receive compensation for claimed losses. From an Allied point of view, these new tribunals served justice, deemed to be at the core of the Paris Peace Treaties system. Yet, for the former Central Power governments, their legal advisers, and scholars, the Mixed Arbitral Tribunals were nothing but elaborate examples of victor’s justice characterized by unclear competences and applicable law.
