In a trial in which Takashi Tachibana, the former leader of the NHK Party, the predecessor of the 48 Political Women's Party, was accused of obstructing NHK's business by obstructing NHK's business by illegally obtaining information from subscribers and threatening to spread it on the Internet, the Supreme Court decided to reject the appeal of former party leader Tachibana by the 23rd, and the conviction of 2 years and 6 months in prison with a 4-year suspended sentence was finalized.

Takashi Tachibana, 48, a former member of the House of Councillors who served as the leader of the NHK Party, the predecessor of the 55 Women's Political Party, was charged with obstruction of business by force and other charges for obstructing NHK's business by illegally obtaining information about subscribers from a former employee of a company that contracts and collects subscription fees in Tokyo and threatening to spread it on the Internet.

At the trial, former party leader Tachibana pleaded not guilty, saying, "It is a political activity and a legitimate business act and not illegal," but the Tokyo High Court in the second trial said, "NHK would not have been forced to take concrete measures without the defendant's actions, stating that he acquired the personal information of unrelated ordinary citizens in order to misuse it in his own activities." He was sentenced to two years and six months in prison with a four-year suspended sentence.

The former party leader had appealed the ruling, but Supreme Court Third Sub-Chamber Chief Judge Yukihiko Imazaki decided to reject the decision by the 4rd, and the suspended sentence was confirmed.
