I think it's 2 Chinese judges who were under investigation. The slide shown last week during Disciplinary Commission report to Congress indicated "Chen" and "Huang" as the two cases pending (and whose decision was expected to be taken in Seville).
Chen and Huang are the surnames of the Chinese judges in Men and Pairs event at Olympics. The slides didn't indicate the first names, so I am not 100% sure it's them but it is possible it is them.
The Olympic Men's judge was Weiguang CHEN and the Pairs judge was Feng HUANG.
