Article 14 7.

In circumstances duly justified by the need to guarantee transparency of key gas supply contracts relevant to the security of gas supply, and where the competent authority of the most affected Member State or the Commission considers that a gas supply contract may jeopardise the security of gas supply of a Member State, of a region or of the Union, the competent authority of the Member State or the Commission may request the natural gas undertaking to provide the contract, excluding price information, for the assessment of its impact on the security of gas supply. The request shall be reasoned and may cover also details of any other commercial agreements that are relevant for the execution of the gas supply contract excluding price information. The justification shall include the proportionality of the administrative burden involved.
