A committee of the Japan Federation of Bar Associations has drafted a proposal that would reverse the group's long-standing opposition to revising the Juvenile Law, federation officials said Tuesday.

If endorsed at its May 1 board meeting, the federation will formally present the proposal when it meets in late May with the Supreme Court and the Justice Ministry, the officials said.

The proposal, made by the Children's Rights Committee, calls for a drastic overhaul of the current juvenile justice system and would allow prosecutors to participate in juvenile inquiry proceedings when facts in connection with crimes are fiercely disputed.
