■ Statement from Bengo Kakumei Developer and Attorney Ryosen Yamamoto
" 'Supreme Court Grand Bench Decision, July 3, 2024' — Case law citation notations like this frequently appear in the documents (case records) handled by lawyers. When lawyers encountered a citation, it was standard practice to open a case law database such as Hanrei Hisho, enter the information into a form, and spend several minutes manually locating the case. The newly released Hanrei Hisho linkage for Bengo Kakumei eliminates these interruptions in workflow, directly connecting documents with case law. If a case notation exists within a preparatory document, it is automatically converted into a link on the Bengo Kakumei screen, allowing users to jump directly to Hanrei Hisho with one click. Users can also easily search for cases while reviewing documents by utilizing the 'Quick Case Law Search.' Bengo Kakumei will continue to enhance the integration of legal knowledge into case records."
