In some recent decisions the European Ombudsman has confirmed the right of every EU citizen both to request information from the EU institutions in any of the 23 official languages and to receive an answer in the official language of their choice. In one case cited by the Ombudsman, the European Commission replied in English to a question written in Irish on the EU's preparation for Irish becoming an official EU language. The Ombudsman, in a decision written in Irish, upheld the complaint. Citizens, companies or associations can bring a complaint before the European Ombudsman in cases where the EU institutions have imposed unjustified restrictions on the right of stakeholders to choose one of the official languages. In contrast, the use of all 23 official languages appears unfeasible with regard to internal communications within the EU institutions. The Ombudsman considered that it was proportionate for EU civil servants to work in one or more “common” language.
