In the course of the exercise of those powers, the competent authorities should comply with the applicable national rules regarding procedures and matters such as the need for a prior judicial authorisation to enter certain premises and legal professional privilege. Those provisions should in particular ensure respect for the fundamental rights to an effective remedy and to a fair trial, including the rights of defence, and, the right to respect for private life. In this regard, the guarantees provided for in relation to the proceedings of the Commission pursuant to this Regulation could serve as an appropriate point of reference. A prior, fair and impartial procedure should be guaranteed before taking any final decision, including the right to be heard of the persons concerned, and the right to have access to the file, while respecting confidentiality and professional and business secrecy, as well as the obligation to give meaningful reasons for the decisions. This should not preclude the taking of measures, however, in duly substantiated cases of urgency and subject to appropriate conditions and procedural arrangements. The exercise of powers should also be proportionate to, inter alia the nature and the overall actual or potential harm caused by the infringement or suspected infringement. The competent authorities should take all relevant facts and circumstances of the case into account, including information gathered by competent authorities in other Member States.
