Article 4
1. At the end of the investigation, the Commission shall submit a report on the results to the Committee referred to in Article 22(1) (‘the Committee’). 2. Where the Commission considers, within nine months of the initiation of the investigation, that no Union surveillance or safeguard measures are necessary, the investigation shall be terminated within a month. The Commission shall terminate the investigation in accordance with the advisory procedure referred to in Article 22(2). A decision to terminate the investigation, stating the main conclusions of the investigation and a summary of the reasons therefore, shall be published in the Official Journal of the European Union . 3. If the Commission considers that Union surveillance or safeguard measures are necessary, it shall take the necessary decisions in accordance with Chapters IV and V, no later than nine months from the initiation of the investigation. In exceptional circumstances, that time limit may be extended by a further maximum period of two months. The Commission shall then publish a notice in the Official Journal of the European Union setting forth the duration of the extension and a summary of the reasons therefor. 4. The provisions of this Chapter shall not preclude the taking, at any time, of surveillance measures in accordance with Articles 7 to 12 or, where a critical situation, in which any delay would cause injury which would be difficult to remedy, calls for immediate intervention, safeguard measures in accordance with Articles 13, 14 and 15. The Commission shall immediately take the investigation measures it considers to be still necessary. The results of the investigation shall be used to re-examine the measures taken.
