Article 6Evidence
6.1 All interested parties in an anti?dumping investigation shall be given notice of the information which the authorities require and ample opportunity to present in writing all evidence which they consider relevant in respect of the investigation in question.
6.1.1 Exporters or foreign producers receiving questionnaires used in an anti?dumping investigation shall be given at least 30 days for reply. Due consideration should be given to any request for an extension of the 30?day period and, upon cause shown, such an extension should be granted whenever practicable.
6.1.2 Subject to the requirement to protect confidential information, evidence presented in writing by one interested party shall be made available promptly to other interested parties participating in the investigation.
6.1.3 As soon as an investigation has been initiated, the authorities shall provide the full text of the written application received under paragraph 1 of Article 5 to the known exporters and to the authorities of the exporting Member and shall make it available, upon request, to other interested parties involved. Due regard shall be paid to the requirement for the protection of confidential information, as provided for in paragraph 5.
6.2 Throughout the anti?dumping investigation all interested parties shall have a full opportunity for the defence of their interests. To this end, the authorities shall, on request, provide opportunities for all interested parties to meet those parties with adverse interests, so that opposing views may be presented and rebuttal arguments offered. Provision of such opportunities must take account of the need to preserve confidentiality and of the convenience to the parties. There shall be no obligation on any party to attend a meeting, and failure to do so shall not be prejudicial to that party's case. Interested parties shall also have the right, on justification, to present other information orally.
6.3 Oral information provided under paragraph 2 shall be taken into account by the authorities only in so far as it is subsequently reproduced in writing and made available to other interested parties, as provided for in subparagraph 1.2.
6.4 The authorities shall whenever practicable provide timely opportunities for all interested parties to see all information that is relevant to the presentation of their cases, that is not confidential as defined in paragraph 5, and that is used by the authorities in an anti?dumping investigation, and to prepare presentations on the basis of this information.
6.5 Any information which is by nature confidential (for example, because its disclosure would be of significant competitive advantage to a competitor or because its disclosure would have a significantly adverse effect upon a person supplying the information or upon a person from whom that person acquired the information), or which is provided on a confidential basis by parties to an investigation shall, upon good cause shown, be treated as such by the authorities. Such information shall not be disclosed without specific permission of the party submitting it.
6.5.1 The authorities shall require interested parties providing confidential information to furnish non?confidential summaries thereof. These summaries shall be in sufficient detail to permit a reasonable understanding of the substance of the information submitted in confidence. In exceptional circumstances, such parties may indicate that such information is not susceptible of summary. In such exceptional circumstances, a statement of the reasons why summarization is not possible must be provided.
