Reviewing the Sporck line of cases (as ‘limited’ by San Juan Hotel Fire Litigation) and developed further, particularly in the District of Columbia District, Magistrate Facciola confirms that an attorney-created index is actually a “hybrid … it was ‘factual in nature but opinionative in structure’ because it organized factual information in a way that might reveal the attorney’s opinions about the case.” Ultimately, however, the sheer volume of documents catalogued may lead the court to deem the index fact-based work product only, where its size makes it virtually impossible to glean any litigation strategy.
