In addition, for the Eurosystem it is also important to mention that system-related tasks are executed in a decentralised fashion through the NCBs in their respective jurisdictions.

All in all, a system of Community law has evolved, also for the euro, which is dominated, in a spectrum from high to low legislative influence, by notions such as unification, harmonisation, approximation, implementation and self-regulation. The road towards unification, if achievable at all, is of an evolutionary nature, where each legal action is determined on a case-by-case basis.
