The wife of House of Councilors member Tatsuo Tomobe has filed an objection to the recent Supreme Court dismissal of her appeal of a lower court ruling sentencing her to five years in prison for fraud, her lawyers said Monday.

The top court has upheld the lower court sentence of Mikiko Tomobe, 65, to five years in prison for conspiring with her husband to swindle 660 million yen from 35 people from 1994 to 1996.

Her 72-year-old husband on Friday also filed an objection to the Supreme Court ruling that upheld a ruling sentencing him to 10 years in prison.

The pair conspired in the swindling through an investment scheme run by a mutual aid society, Orange Kyosai Kumiai, which Tatsuo Tomobe ran, according to the ruling.

The top court has never reversed or withdrawn a ruling after a petition has been filed, except in cases where a defendant died or for other technical reasons.
