In To seal the deal: mechanisms for the validation of political settlements, Christopher Thornton and Felix Tusa explore how political settlements can be validated in democratic societies and the problems, benefits and risks associated with existing validation methods.

They argue that a careful combination of different methods – such as seeking a broad mandate to negotiate, seeking parliamentary validation of the deal, and requesting a court judgment on the validity of the process and any consequent agreement – can provide legitimacy for peace settlements without putting those settlements at risk.
