This chapter looks at how the demand placed by international law on domestic systems can be leveraged by domestic actors such as courts to expand the scope of constitutional and other protections within states, deepening rights protections over time. It builds on Thomas Franck's 'democratic entitlement' argument in a novel way, where international law is not imposed by outsiders but relied upon by progressive actors within domestic societies as a possible bulwark against majoritarianism and authoritarianism.
