ATHENS — Greek lawmakers voted early Tuesday in favor of indicting former Finance Minister George Papaconstantinou over the way he handled a list of more than 2,000 Greeks with Swiss bank accounts, a possible source of much-needed tax revenue that was never exploited by the authorities.

In a secret ballot that followed a contentious debate, a majority of lawmakers in Greece’s 300-seat Parliament said that Mr. Papaconstantinou should stand trial on three charges: breach of trust, tampering with an official document and breach of duty.

The votes lifted Mr. Papaconstantinou’s immunity from prosecution for the time he was a cabinet minister. A council of judges will now decide whether he should face the criminal charges outlined in Parliament.

In an impassioned speech before the vote, Mr. Papaconstantinou claimed that he was being made a scapegoat for “the sins of a series of governments,” accusing the parliamentary committee that recommended the indictment vote of a “blatant attempt at fabricating guilt.” He contended that Greece’s financial crimes unit had the opportunity and motive to tamper with the list “with or without political intervention.”
