Mechanism for Cooperation and Verification

The Mechanism for Cooperation and Verification (CVM) is a safeguard measure invoked by the European Commission when a new member or acceding state of the European Union has failed to implement commitments undertaken in the context of the accession negotiations in the fields of the Area of freedom, security and justice or internal market policy.

Common practice in the EU is that during accession negotiations there are agreed some temporary transitional periods after accession of new states for derogation of application for specific parts of the acquis communautaire, because of difficulties either for the new member state (for example environmental regulations for large combustion plants) or for the old member states (for example free movement of workers). Such temporary transitional periods in regard to particular member states are also implemented when various new pieces of EU legislation are adopted (or in a new treaty adoption or amendment).

In some cases the derogation is not temporary, but permanent. Such derogations could be one of the major Opt-outs in the European Union (formulated in a treaty) or some minor derogations like the exemption of Sweden from the snus ban (formulated in EU legislation).
