A final appeal may be filed against a high court judgment of first or second instance on the grounds that:
高等裁判所がした第一審又は第二審の判決に対しては、左の事由があることを理由として上告の申立をすることができる。
There is a violation of the Constitution or an error in the interpretation of the Constitution;
A determination has been rendered that conflicts with a Supreme Court precedent; or
最高裁判所の判例と相反する判断をしたこと。
In the event that there is no Supreme Court precedent, a determination has been rendered that conflicts with a precedent of the former Supreme Court (daishin'in) or a high court that was the court of the final appellate instance, or that conflicts with a precedent of a high court that was the court of second instance at a time after the enforcement date of this Act.
最高裁判所の判例がない場合に、大審院若しくは上告裁判所たる高等裁判所の判例又はこの法律施行後の控訴裁判所たる高等裁判所の判例と相反する判断をしたこと。
Supreme Court
最高裁判所
The highest court, and the court of last resort on whether any law, order, regulation or official act conforms to the Constitution (Article 76, paragraph (1), and Article 81). That power is what makes the Constitution enforceable: there is no penalty attached to breaching it, and instead a conflicting rule is held to have no legal force (Article 98, paragraph (1)). Its judges are reviewed by the people at the first general election after appointment, and again after ten further years (Article 79, paragraph (2)).
