NEW YORK -- An email from a federal judge in Brooklyn arrived unexpectedly one day in late May, requesting my appearance in court. "It may seem to be ancient history," the judge wrote, but there was a seismic development in a landmark legal case that I had helped set off nearly a quarter-century ago. Several weeks later, scores of federal and state officials, lawyers and leaders of advocacy groups gathered for a hearing in a packed Brooklyn courtroom used for ceremonial events.
