Aldridge eventually sued Allstate, alleging that the insurer acted in bad faith by not paying Deer’s claim. Only then did his lawyers make an important discovery: a management consulting firm, McKinsey & Company, had been advising Allstate through PowerPoint slides on how to save money on claims. So they asked Allstate to produce the slides. After Allstate refused, the judge in the case, Michael Manners, ordered Allstate to turn them over.
