Pope Francis has instructed a Vatican commission to draft a new doctrine for excommunicating Catholics convicted of corruption or mafia-related crimes.

More than 50 prosecutors, bishops, United Nations representatives and victims of organized crime came together for a Vatican conference this week to hammer out the Church’s new legal doctrine concerning “the question of excommunication for corruption and mafia association.”

"Our effort is to create a mentality, a culture of justice, that fights corruption and promotes the common good," said Archbishop Silvano Tomasi, the Vatican's retired ambassador to the U.N. in Geneva, who was one of the conference participants.
