IBM is trying to block a lawsuit by European gypsies which alleges the company allowed its punch-card machines to be used by the Nazis in the Second World War to improve their genocide effort.
On 20 August, the US computer giant quietly appealed the case to the Swiss Federal High Court, the country's highest judicial body. An IBM spokesman confirmed the legal action earlier this week but declined to comment on pending litigation.
IBM has good reason to be tight-lipped about the lawsuit: substantial compensation and the image of an industry icon may hinge on the decision of the Swiss court.
The group of Gypsies, called the Gypsy International Recognition and Compensation Action (GIRCA), is seeking up to$12 billion in collective damages. But the legal process has been long and arduous, and its outcome is still anything but certain.
"If the Federal High Court overrules an earlier decision by the Geneva appeals court, the case is over," the group's lawyer, Henri-Philippe Sambuc, said. "If it doesn't overrule the decision, then the case moves back to the First Instance Court. This could result in years of litigation."
In June, the Geneva Court of Appeal overruled the city's First Instance Court, which a year earlier had dropped GIRCA's case against Big Blue. The lower First Instance Court said the computer company had only a small office in the city, and decided not to hear the case.
But in its ruling, the appeals court cited a "significant" body of evidence showing that IBM had a major office in Geneva and that this office could have been aware it was assisting criminal acts of the Nazis.
From the start, GIRCA has argued that IBM had a non-registered operation in Geneva, called International Business Machines Corporation New York, European Headquarters, and that this organisation is well documented in the book "IBM and the Holocaust: The Strategic Alliance Between Nazi Germany and America's Most Powerful Corporation" by Edwin Black.
In his book, Black said that IBM - through its German subsidiary, Deutsche Hollerith Maschinen GmbH (Dehomag) - provided the punch-card data processing systems that allowed Nazis to categorise and track concentration camp victims, who were mostly Jews, and that the company was aware of how its equipment was being used.
