Greece's former finance minister, George Papaconstantinou, has been indicted before a special court on criminal charges over his handling of data on Greeks holding Swiss bank accounts.
A council of Supreme Court judges ruled Thursday that Papaconstantinou, 53, should stand trial for alleged breach of faith and tampering with an official document.
The Socialist former minister, who handled Greece's first international bailout in 2010, denies wrongdoing. If convicted, he faces a minimum 10-year prison sentence.
The accusations related to a list of about 2,000 names provided by French authorities in 2010.
Greek authorities failed to investigate the data for potential tax evasion, and the names of three of Papaconstantinou's relatives allegedly were removed from the list.
No date has been set for a trial.
