Millions saved in document review by health care client

The Challenge

A leading healthcare company was faced with a significant document review of approximately 2.5 million documents. Unexpectedly and shortly after the project began, an additional 2 million documents were added to the review corpus.

The Solution

Legility leveraged the institutional knowledge and specific experience that its core team of attorneys gained through their years of working on this client’s matters, and targeted the review on those documents most likely relevant to the matter. Using agile business processes, the Legility attorney team recommended and performed incremental reviews of statistically valid random samples before and during the review, and was able to provide supervising outside counsel with key metrics throughout the review to make the most informed strategic decisions on behalf of the mutual client:

  1. Millions of documents 
    Provided statistical range of relevant documents likely to be found in the database of millions of documents.
  2. Relevant documents & custodians 
    Identified the most effective key terms to find relevant documents and, conversely, those terms or syntax of search terms that generated the most "false" hits; identified the most relevant custodians.
  3. Defensible document reduction
    Identified the large tranches of clearly non-relevant material that could be defensibly deleted from the review set.


The real-time sampling results and recommendations from this process allowed the client and supervising counsel to confidently target the review and eliminate the unnecessary review of millions of clearly non-relevant documents, saving the client millions of dollars in attorney review and saving months of time in the process.

Aggressive deadline met,  millions saved.
