Article 4 7.

Where a reasoned opinion of ACER identifies a case of potential non-compliance of the ENTSO for Electricity, the ENTSO for Gas, the ENNOH, the EU DSO entity or a regional coordination centre with their respective obligations, the regulatory authorities concerned shall unanimously take coordinated decisions establishing whether there is non-compliance with the relevant obligations and, where applicable, determining the measures to be taken by the ENTSO for Electricity, the ENTSO for Gas, the ENNOH, the EU DSO entity or the regional coordination centre to remedy that non-compliance. Where the regulatory authorities fail to take such coordinated decisions unanimously within four months of the date of receipt of ACER’s reasoned opinion, the matter shall be referred to ACER for a decision pursuant to Article 6(10).
