​​​​​​The Board of Regulators plays a key role within the Agency. It is in charge of the regulatory policy and provides opinions on various Agency Acts considered for adoption and issues guidance to the Director.

It approves the Agency’s work programme and is consulted on other key matters.

The Board of Regulators consists of senior representatives of the 27 National Regulatory Authorities (NRAs) of Member States and non-voting representatives from EEA EFTA States, the European Commission and the EFTA Surveillance Authority.

The Board of Regulators must act independently and must not take instructions from any government of a Member State, from the European Commission, or from another public or private entity.​

The Board of Regulators adopts its rules of proc​edure, regulating the way NRAs cooperate together through ACER. 

Decisions of the BoR are adopted on the basis of a two-thirds majority of the members present (each membe​r has only one vote).​​​

​On 4th October 2019, the ACER Board of Appeal has amended its Rules of Procedure, in accordance with Regulation (EU) 2019/942. 

To support parties acting in compliance with the legal requirements and prepare their appeals in the most effective way, the Board of Appeal has adopted Practice Directions and a set of templates (cover sheet with general information, table of annexes, confidentiality request, announcement of appeal and a checklist). 

Whilst they are not compulsory, the Board recommends their use to avoid​ possible delays or declarations of inadmissibility.​

The Board of Appeal has also adopted Instructions to the Registrar which can be found in the box below.

The relationship of the Board of Appeal and the Agency in administrative terms is governed by the Administrative Arrangement.​
