なぜ田久保眞紀被告は卒業証書を出さなくても許されるのか「偽造文書なき文書偽造裁判」の行方を元テレビ朝日法務部長が解説（デイリー新潮） - Yahoo!ニュース

This page explains the unusual legal situation in the trial of Maki Takubo, former mayor of Ito. Her defense lawyer refuses to submit an alleged fake diploma, citing the attorney-client privilege based on the Carlos Ghosn case ruling. In Japan, evidence destruction is only punishable in "other people's" criminal cases, not one's own. Therefore, a defendant can legally conceal evidence related to their own case. The prosecution faces the challenge of proving forgery charges without the actual document, making this an exceptional trial.
