Main text of the judgment (decision)

Jokoku appeal is dismissed.

Reasons

Ground (1) for Jokoku appeal of the Appellant's attorney MOMOYA Kazuhide, including the claim of unconstitutionality, amounts to a claim of simple statutory violation. Ground (2), a claim of a breach of judicial precedent, is inapposite since in the case cited and relied upon, the court held only that it was not unlawful to record a conversation or similar exchange without the consent of the other party under the circumstances of the case then at hand. Therefore, neither contention amounts to grounds for a Jokoku appeal.

Deciding this case ex officio, this Court will proceed to examine Jokoku Appellant's arguments:
[Summary] The tape recording examined as evidence in this case is a recording of a conversation with Appellant that was made for use as evidence by a person who believed himself to have been defrauded by Appellant and who distrusted Appellant's explanation. Under these circumstances, it is not unlawful for one party to a conversation to make a tape recording thereof without the other party's consent, and the contention that the aforesaid tape recording is inadmissible as evidence is groundless.

Therefore, in accordance with Article 414 and Article 386, para. 1, sub-para. 3 of the Code of Criminal Procedure, this Court unanimously finds as stated in the main text of the decision above.
