How to ‘make law count’: Lessons from the Comisión Internacional contra la Impunidad en Guatemala (CICIG) for the Effectiveness of Hybrid Governance

The international community has experimented with a variety of tools for promoting the rule of law in weak states, yet with few successes. An innovative tool is hybrid commissions not supplanting the justice system of the target state but fighting impunity from within it. In this contribution I therefore seek to identify the factors that render this novel mechanism of rule of law promotion effective, arguing that a set of factors – support from the Attorney-General, civil society and powerful donors; as well as the commission’s institutional design, its strategy, and the personality of the commissioner – will determine if the changes initiated by the hybrid lead to a deeper transformation of the host state, or if there will be a rule of law rollback as soon as the commission leaves the country.
