Customs Union Protocol

What emerges from this case law is a unitary system of sources of law, with the EACJ having the power to police their hierarchical compatibility and invalidate a lower-ranking norm if it contradicts a higher-ranking one. Such an arrangement is typical for federal states; the EACJ positions itself as a guardian of hierarchical compatibility of norms within the federal system, and consequently as a constitutional court within such a system.

Variable geometry is an operational principle under the Treaty for the Establishment of the East African Community (the EAC Treaty). Much like the European Union’s ‘enhanced cooperation’ provisions, the objective of variable geometry is to reinforce the integration process by allowing progression of cooperation among a group of partner states within the Community in chosen areas and at different speeds. The underlying principle of flexibility is seen in both the Union and Community contexts albeit with necessary procedural differences. Other similarities lie in the requirement that cooperation must be left open to any member state wishing to join later, and that such cooperation can only be invoked as a last resort.
