ABSTRACT
On 1 January 2015, a new international organisation was launched in the post-Soviet space, the Eurasian Economic Union (EAEU). While the European Union (EU) tends to exemplify the most 'supranational', highly institutionalised end of the spectrum, it is recognised that all organisations entail some erosion of absolute state sovereignty, with Member States voluntarily granting powers for the purposes of achieving the organisation's objectives. The EU's model has underscored the ability of the organisation to enact binding decisions directly applicable to Member States and its citizens. The experience of the Commonwealth of Independent States (CIS) led to the emergence of a 'law of the CIS'. The resulting institutional set-up places a huge emphasis on the presence of effective domestic constitutional mechanisms to ensure the supremacy of the common regime. Post-Soviet integration has been characterised by weak disciplinary and enforcement mechanisms. Despite the fact that a permanent dispute resolution body was created, the Economic Court of the CIS, its design was problematic.
