Chapter 8a: Document Review

What is Document Review in eDiscovery?

Document review in the context of eDiscovery is where legal professionals examine digital documents to separate relevant information from irrelevant information and identify privileged data. It is normally present in disclosure exercises in litigation, arbitration, internal investigations, etc.

Overview and Significance of Document Review

This phase is integral to eDiscovery, shaping the case’s direction and strategy. It requires a balanced approach, aligning legal compliance with strategic case development, significantly influencing legal arguments and proceedings.

Participants in Document Review

Law firms or specialized review service vendors typically handle document review by using their expertise in complex data and legal intricacies. For smaller cases, in-house reviews are conducted for better resource management. Building an effective review team involves selecting individuals with detailed legal knowledge and proficiency in eDiscovery technologies, whether in-house or outsourced.

eDiscovery Document Review Workflow

The eDiscovery document review workflow is a critical and structured series of steps by legal professionals. It involves meticulously reviewing and analyzing documents in a review tool to establish their relevance to the case and also identify any protected information. This comprehensive process is essential and requires a balance of efficiency, thoroughness, and adherence to legal standards.

• Understanding Case Issues: Grasping the case’s core issues is fundamental. This step involves identifying key elements such as relevant keywords, significant names, and relevant date ranges. This knowledge is not just about comprehending the facts but also about understanding their implications and how they intertwine with the case’s narrative.
• Strategic Development of Review Approach: Once the case’s nuances are understood, the next step is formulating a strategic review plan. This involves aligning the document review with the legal team’s objectives, considering the factual background and the desired legal outcome. Reviewers must be adaptable and ready to adjust their approach based on emerging patterns and insights that might suggest a shift in strategy, such as adopting a more assertive defense or considering settlement options.
• Rigorous and Consistent Document Tagging: Maintaining a systematic approach to tagging is critical in document review. Every document should be accurately labeled with a standardized set of tags – these could range from basic classifications like ‘relevant,’ ‘irrelevant,’ or ‘privileged’ to more detailed descriptors such as ‘incriminating,’ ‘adverse,’ ‘impartial,’ or ‘beneficial.’ This tagging framework must be transparent and uniformly adopted by all reviewing members in order to ensure a cohesive organization of the final document collection.
• Balancing Efficiency with Accuracy in Review: In document review, efficiency is as important as accuracy and thoroughness. Review teams should establish clear productivity benchmarks, setting expectations for the number of documents to be reviewed within a specific timeframe. This approach is particularly important considering the financial implications of document review projects, which can escalate into significant costs. Regular tracking and evaluation of review speeds versus accuracy help address any productivity issues, ensuring a cost-effective yet precise review process.
• Analysis Phase: This phase of the consideration process focuses on understanding trends and patterns within the already reviewed data. The insights gained are used to modify strategies for the remaining dataset and to determine the next course of action in the eDiscovery process.

Defining Search Terms for Document Review and Validation Process

Defining search terms in eDiscovery document review is crucial for efficiently filtering out relevant documents. This process requires a blend of skill, strategy, and technology to balance the need for comprehensive data retrieval with the efficiency of the review process. (Please note this chapter is referring to the technical aspects only. Ultimately, the legal authority and other parties to the case will be involved in the decision-making.)

Balanced Term Selection

• Employing Boolean Logic: Boolean logic uses specific operators to refine search results. This approach helps in precisely narrowing down the data set.
  • Examples:
    • Using “AND” to combine terms: If looking for documents related to a “contract dispute” in “2019,” the search term could be “contract AND dispute AND 2019.” This will return documents that contain all these terms.
    • Using “OR” for broader searches: To find documents related to either “mergers” or “acquisitions,” the term could be “mergers OR acquisitions.” This will return documents that contain either of the terms.
    • Using “NOT” to exclude terms: If you want to find documents about “financial reporting” but not “taxes,” the search could be “financial reporting, NOT taxes.”

• Variations and Refinement: This involves considering different variations of keywords, including common misspellings, synonyms, and industry jargon, to ensure comprehensive coverage.
  • Examples:
    • Variations in spelling: If searching for documents related to “embezzlement,” including common misspellings like “embezzlement” or “embezzlement” can capture more relevant documents.
    • Considering synonyms and jargon: For a case involving “intellectual property,” including terms like “IP,” “patents,” or “copyrights,” can broaden the search to cover industry-specific language.
    • Iterative refinement: Start with a broad search like “fraud OR embezzlement OR theft” and then refine based on initial results, possibly narrowing down to specific types of fraud or including additional terms related to the case context.

Validation Techniques

• Testing for Accuracy: The validation of key terms involves applying them to a sample data set and manually assessing the results for accuracy and relevance. If the sample yields potential evidence of importance to the case, the key terms are considered valid for application across the entire data set.
• Balancing Specificity and Breadth: Finding the right mix of specific and broad terms is the key to covering all potentially relevant data without overwhelming the review team with irrelevant information.

Challenges in eDiscovery Document Review

The document review phase in eDiscovery presents several challenges that require strategic solutions to ensure effective and efficient outcomes. For example, handling the sheer volume of digital data and the diversity in data types. In the past, there used to be only emails and computer data; however, today, data types include chat, social media, and IoT (Internet of Things) device data. Another example is meeting the time-sensitive demands of cases and coordinating with remote reviewers in today’s hybrid working environments. These factors necessitate efficient strategies to ensure timely and effective review without compromising data integrity.
