Article 75 - Union restrictions for third-country non-covered economic operators, goods, services and works
Article 75 appears to be a simple article, giving the European Commission the powers to adopt the necessary delegated acts to mandate the application of the European preference included in Article 73 in accordance with the conditions imposed by Article 141. What is optional and to the discretion of the public buyer under that Article may become mandatory if the Commission so decides to.
This conferral of power is not time limited as per Article 141(2) but may be revoked at any time by either the European Parliament or the Council. The revocation of the power does not affect the standing of the legal acts approved by the Commission in the meanwhile.
