Restrictions on Inspection to Preserve Confidential Information(秘密保護のための閲覧等の制限)
Article 92, paragraph (1)
If a party to a case makes a prima facie showing of the following grounds, the court, at the petition of that party, may rule to limit the persons who may request access to the parts of the case records that contain the confidential information in question (meaning access to hard-copy case records or access to electronic or magnetic case records; the same applies in Article 133, paragraph (3)) (referred to below as "access to the confidential parts of the case records" in this Article) to the parties to the case:
a material piece of confidential information about the private life of a party appears in the case record, and a third party's access to the confidential parts of the case records would be likely to substantially interfere with that party's public life;
a trade secret (meaning a trade secret as prescribed in Article 2, paragraph (6) of the Unfair Competition Prevention Act; the same applies below) being kept by a party to the case appears in the case records.
Once a petition as referred to in the preceding paragraph has been filed, a third party may not request access to the confidential parts of the case records until a judicial decision on the petition becomes final and binding.
A third party seeking access to the confidential parts of the case records may file a petition with the court of record to set aside the ruling stated in paragraph (1), on the grounds that any requirement prescribed in that paragraph has not been met or is no longer being met.
An immediate appeal may be filed against a judicial decision denying the petition stated in paragraph (1) and against a judicial decision on the petition stated in the preceding paragraph.
第一項の申立てを却下した裁判及び前項の申立てについての裁判に対しては、即時抗告をすることができる。
Article 92, paragraph (5)
A judicial decision setting aside a ruling as referred to in paragraph (1) does not come into force unless it becomes final and binding.
第一項の決定を取り消す裁判は、確定しなければその効力を生じない。
Article 92, paragraph (6)
If a petition under paragraph (1) (limited to a petition filed due to the existence of grounds stated in item (i) of that paragraph; the same applies in the following paragraph and paragraph (8)) has been filed and a third party intervenes in the litigation after its filing, the court clerk must notify the party who filed the petition of the intervention immediately after the intervention; provided, however, that this does not apply if the judicial decision denying the petition has become final and binding.
In a case as referred to in the main clause of the preceding paragraph, the court clerk may not permit the intervener to access the confidential parts of the case records about which the petition under paragraph (1) was filed, during the time that runs from the day of the notification under the provisions of that paragraph until the final day in the two-week period that follows; provided, however, that this does not apply if a petition as referred to in Article 133-2, paragraph (2) has been made.
The provisions of the preceding two paragraphs do not apply if all parties that have filed the petition under paragraph (1) consent to allow the intervener referred to in paragraph (6) to access the confidential parts of the case records about which the petition under paragraph (1) has been filed.
If a petition under paragraph (1) (limited to one filed because the grounds stated in item (ii) of that paragraph exist; the same applies in the following paragraph) is filed, and if the use of a trade secret detailed in that petition for purposes other than conducting the suit, or the disclosure of that trade secret, would likely interfere with the party's business activities that are based on that trade secret, and the court finds it to be particularly necessary to do so in order to prevent this, the court may output the parts of the electronic or magnetic case records containing that trade secret in paper format or record them onto another recording medium, as well as taking measures to delete them from the electronic or magnetic case records or any other measures specified by the Rules of the Supreme Court as necessary and appropriate to securely manage the trade secret.
If, after measures under the provisions of the preceding paragraph are taken to delete parts of the electronic or magnetic case records, a judicial decision denying the petition referred to in paragraph (1) becomes final and binding, or a judicial decision setting aside the decision concerning the petition becomes final and binding, the court clerk must record the part of the records containing the trade secret in the court's computer files.
