The Democratic Party of Japan-led government recently approved a bill to abolish the statute of limitations on crimes that could be punishable by hanging in a move experts say signals a major shift in the justice system.

The bill, which would amend the Criminal Procedure Law and the Penal Code, also would lift the maximum statute of limitations to 30 years for crimes punishable by life imprisonment, to 20 years for crimes punishable by 20 years of imprisonment, and to 10 years for crimes punishable by lesser prison terms.

The bill is based on proposals submitted to the justice minister in February by the ministry's Legislative Council. They discussed the revision based on the findings of the study group that worked under the previous Liberal Democratic Party-led government.
