The Supreme Court has upheld lower court rulings that found a former secretary to veteran lawmaker Ichiro Ozawa guilty of failing to report political funds, the top court said Wednesday.

On Tuesday, the court's No. 3 Petty Bench led by Justice Masaharu Ohashi turned down an appeal from Tomohiro Ishikawa, a 41-year-old former member of the House of Representatives who was sentenced to two years in prison, suspended for three years, for falsifying the political fund reports of Ozawa's fund management body.

Ozawa now heads People's Life Party, a small opposition force.
