The Supreme Court said Wednesday it has rejected lower and high court decisions to hold a retrial for a 92-year-old woman who served 10 years in prison over the 1979 murder of her former brother-in-law in Kagoshima Prefecture.

All five Supreme Court judges made the unanimous decision on Tuesday to dismiss the retrial of Ayako Haraguchi after the district court granted the retrial request and the high court upheld the decision.

It is the first time since 1975 that the top court has rejected a retrial decision made by a district court and upheld by a high court.
