Société Générale insider trading conviction

In 1988, Soros was contacted by a French financier named Georges Pébereau, who asked him to participate in an effort to assemble a group of investors to purchase a large number of shares in Société Générale, a leading French bank that was part of a privatization program (something instituted by the new government under Jacques Chirac). Soros eventually decided against participating in the group effort, opting to personally move forward with his strategy of accumulating shares in four French companies: Société Générale, as well as Suez, Paribas, and the Compagnie Générale d'Électricité.

In 1989, the Commission des Opérations de Bourse (COB, the French stock exchange regulatory authority) conducted an investigation of whether Soros's transaction in Société Générale should be considered insider trading. Soros had received no information from the Société Générale and had no insider knowledge of the business, but he did possess knowledge that a group of investors was planning a takeover attempt. Initial investigations found Soros innocent, and no charges were brought forward. However, the case was reopened a few years later, and the French Supreme Court confirmed the conviction on June 14, 2006, although it reduced the penalty to €940,000.

Soros denied any wrongdoing, saying news of the takeover was public knowledge and it was documented that his intent to acquire shares of the company predated his own awareness of the takeover. In December 2006, he appealed to the European Court of Human Rights on various grounds, including that the 14-year delay in bringing the case to trial precluded a fair hearing. On the basis of Article 7 of the European Convention on Human Rights, stating that no person may be punished for an act that was not a criminal offense at the time that it was committed, the court agreed to hear the appeal. In October 2011, the court rejected his appeal in a 4–3 decision, saying that Soros had been aware of the risk of breaking insider trading laws.
