Abstract Scholars have argued that the convention method has democratised the process of treaty reform and increased the legitimacy of EU constitutionalisation. This article finds that the convention method has contributed to a slightly more democratic process, but has not, in any fundamental way, improved the democratic status of the EU's treaty reform process. We should accordingly not be too concerned over the future fate of the convention method. From a democratic perspective, we should be more worried over the possible scenario that future changes to the EU's institutional structure will come about through implicit constitutional change without any formal changes being made to the treaties. The often cumbersome ratification process could thereby be bypassed, but this would also deprive EU citizens of the only real opportunity they have of influencing decisions on the overall design of the integration project.
