Xi Xiaoming, vice president of the Supreme People's Court, has been probed for "serious violations of discipline and laws," China's top anti-corruption body said today.
"Serious violations of discipline" usually meant corruption case.
Xi is also member of the top court's leading ruling Communist Party of China (CPC) members' group, the Central Commission for Discipline Inspection of the Communist Party of China in a statement.
Thousands of CPC officials from different departments including the military faced anti-graft probes since President Xi Jinping took over power two years ago.
Xi, 61, broke the norm as pressed ahead with the two-year anti-corruption campaign against "tigers and flies", meaning all ranks in order to restore the sagging credibility of the party among people.
