that, while prosecutors very rarely demand the death penalty in cases of single murder, death sentences were passed in 32% of those cases where they requested it. On the other hand, prosecutors seek the death penalty almost systematically in cases of multiple homicide, and 59% of cases of double-murder and 79% of cases where three or more victims have been killed result in death sentences being passed. The study also found that death sentences were passed in all cases of convicted murderers who killed again after being released on parole from life prison terms, and in all robbery-murder cases with three or more people killed. Furthermore, in 5 of 10 kidnap-for-ransom cases in which one person was killed, the defendants were sentenced to death. Judicial process Since May 2009, district courts try capital cases using the lay judge system, where three professional judges sit with six randomly chosen citizens. Five votes of nine-member court, including at least one professional judge, are required for issuing a conviction and any punishment, including death. Japan has a civil law legal system; therefore, appeal courts retry both facts and law. High courts retry cases with only three judges and no lay judges, and can either reduce a death sentence to life or raise a life sentence to death. Ultimately, a five-member petty bench of the Supreme Court has the final say on the penalty, Article 411 of Code of Criminal Procedure allowing it to remand the case or change the punishment if the one handed down by the high court is "seriously unfair". In only three cases since 1945 has the Supreme Court ruled a high court-imposed life sentence too lenient and ordered a retrial for death sentence. Among them are Norio Nagayama and Takayuki Fukuda, both under 20 at time of crime. The third case was that of a man convicted of murdering an elderly woman for robbery shortly after being paroled from a life sentence imposed for a similar crime. Stays of execution According to Article 475 of the Japanese Code of Criminal Procedure, the death penalty must be executed within six months after the failure of the prisoner's final appeal upon an order from the Minister of Justice. However, the period requesting retrial or pardon is exempt from this regulation. Therefore, in practice, the typical stay on death row is between five and seven years; a quarter of the prisoners have
