A bill to amend the Criminal Procedure Law and revise Japan's retrial system entered deliberation in the House of Councillors on June 19, 2026 [1].
The legislation seeks to overhaul how the Japanese legal system handles claims of wrongful conviction. If passed, it would change the mechanisms used to grant retrials, which critics argue have historically been too restrictive to protect the innocent.
Prime Minister Takashi said the revision will ensure reliable relief for wrongful convictions and speed up retrial procedures [2]. The administration argues that the current system requires a more streamlined approach to ensure that those erroneously convicted can find a faster path to exoneration.
However, opposition lawmakers have challenged the sufficiency of the bill. Lawmaker Uchikoshi of the Constitutional Democratic Party said the legislation leaves many loopholes regarding prosecutor appeals, evidence lists, and the prohibition of using evidence for purposes other than the retrial [2]. Uchikoshi asked if the prime minister believed this specific bill could truly achieve reliable relief from wrongful convictions [2].
Pressure is mounting on the government to finalize the legislation quickly. A senior aide to the prime minister said there is a mountain of work to do and that there is simply no time [2]. This urgency comes as the Diet session has less than one month remaining [1].
While the bill entered the Upper House on June 19, it had previously undergone substantive deliberation in the House of Representatives Committee starting May 27, 2026 [3]. The current debate in the House of Councillors represents the final legislative hurdle for the amendment.
Supporters of the bill believe the changes will modernize the judiciary, while opponents demand further amendments to close the gaps they claim still exist in the legal framework [2].
““This bill will realize certain relief from erroneous judgments and the smooth and rapid promotion of retrial procedures,” said Prime Minister Takashi.”
The push to reform the retrial system reflects a long-standing tension in Japan's judiciary between maintaining the finality of court rulings and addressing the risk of wrongful convictions. By attempting to pass this law with less than one month left in the session, the Takashi administration is prioritizing a rapid legislative win, but the opposition's focus on 'loopholes' suggests that the legal community remains divided on whether the changes provide substantive protection or merely procedural efficiency.
