According to Public Information Act Article 35 there are several grounds for classification of information as internal. According to the referred Article section 1 subsection 3 a holder of information (in our case Estonian Competition Authority) is required to classify the following as information intended for internal use: information the disclosure of which would damage the foreign relations of the state. Also according to the referred Article section 1 subsection 17 a holder of information (in our case Estonian Competition Authority) is required to classify the following as information intended for internal use: information whose disclosure may violate a business secret. According to Competition Act Article 63 section 3 an official of the Competition Authority may disclose and use a business secret of an undertaking if this is necessary for establishing an offence related to competition, or a violation of this Act or Article 101 or Article 102 of the Treaty on the Functioning of the European Union. An official of the Competition Authority may submit documents containing a business secret only to a court for preparation of the hearing of a criminal, civil, administrative or misdemeanour matter, or for the hearing of or making a court decision in such matter.
