If Bulgaria or Romania has failed to implement commitments undertaken in the context of the accession negotiations, causing a serious breach of the functioning of the internal market, including any commitments in all sectoral policies which concern economic activities with cross-border effect, or an imminent risk of such breach the Commission may, until the end of a period of up to three years after accession, upon the motivated request of a Member State or on its own initiative, adopt European regulations or decisions establishing appropriate measures.
Measures shall be proportional and priority shall be given to measures which least disturb the functioning of the internal market and, where appropriate, to the application of the existing sectoral safeguard mechanisms. Such safeguard measures shall not be invoked as a means of arbitrary discrimination or a disguised restriction on trade between Member States. The safeguard clause may be invoked even before accession on the basis of the monitoring findings and the measures adopted shall enter into force as of the first day of accession unless they provide for a later date. The measures shall be maintained no longer than strictly necessary and, in any case, shall be lifted when the relevant commitment is implemented. They may however be applied beyond the period specified in the first paragraph as long as the relevant commitments have not been fulfilled. In response to progress made by the new Member State concerned in fulfilling its commitments, the Commission may adapt the measures as appropriate. The Commission shall inform the Council in good time before revoking the European regulations and decisions establishing the safeguard measures, and it shall take duly into account any observations of the Council in this respect.
