In the above case, the Board of Directors may decline to provide information for a very significant reason, which must be mentioned in the minutes.

Given the circumstances, such a reason may be, the representation of the applicant shareholders at the Board of Directors, pursuant to articles 79 or 80 of Law 4548/2018.

In the aforementioned case, the Board of Directors may provide an overall response to requests of shareholders of the same content.

In the aforementioned cases (c) and (d), any doubt/challenge on the reasoning of the decline on behalf of the Board of Directors to provide information, will be settled by the Court, according to judgement issued in the context of interim proceedings. According to this judgement/decision, the Company is obliged to provide the relevant information. The decision cannot be challenged by legal remedies.
