The case, which has been working its way through Swiss courts since 2001, was brought by Gypsy International Recognition and Compensation Action (GIRCA), which is seeking up to $12 billion in collective damages...For its part, IBM has claimed that it lost control of its German subsidiary -- dubbed Deutsche Hollerith Maschinen GmbH, or Dehomag -- before war began in 1939.
