It must therefore be determined whether national rules relating to the transcription in Roman characters of the name of a Greek national in the registers of civil status of the Member State in which he is established are capable of placing him at a disadvantage in law or in fact, in comparison with the way in which a national of that Member State would be treated in the same circumstances.

Rules of that kind are to be regarded as incompatible with Article 52 of the Treaty only in so far as their application causes a Greek national such a degree of inconvenience as in fact to interfere with his freedom to exercise the right of establishment enshrined in that article.

It should therefore be stated in reply to the national court that Article 52 of the Treaty must be interpreted as meaning that it is contrary to that provision for a Greek national to be obliged, under the applicable national legislation, to use, in the pursuit of his occupation, a spelling of his name whereby its pronunciation is modified and the resulting distortion exposes him to the risk that potential clients may confuse him with other persons.
