E-discovery in Guernsey: navigating electronic disclosure in litigation

For litigants and practitioners in Guernsey, understanding the implications of e-discovery, early consideration about where potentially relevant data is stored, how it is accessed and preserved, can help avoid disputes, reduce costs and ensure compliance with disclosure obligations.

In today's digital world, immeasurable amounts of information are created, shared and stored electronically. The days when disclosure exercises were confined to paper files are long gone. Emails, cloud-based documents and collaboration platforms have largely replaced traditional paper records, leaving a growing digital footprint and making electronically stored information (ESI) increasingly prevalent.

This insight explores the key principles of e-discovery in the Guernsey context, highlights common challenges and outlines practical steps organisations can take to prepare for litigation.

E-discovery in Guernsey: legal and procedural framework

E-discovery is the process of identifying, preserving, collecting, processing, reviewing and producing ESI for use in litigation. It assists parties in locating and disclosing relevant documents, including material that supports or undermines their case. The purpose is to ensure all potentially relevant information is available so parties are on an equal footing, and the litigation can be conducted fairly and transparently.

The principles of disclosure apply equally whether documents are paper or electronic. However, modern electronic data creates additional legal and practical issues due to its volume, variety and complexity, while metadata, version histories and embedded content can provide valuable additional evidence. Questions about preservation, privacy, privilege and proportionality frequently arise and can have a significant impact on the scope, cost and outcome of disclosure.

In Guernsey, the disclosure process is governed by the Royal Court Civil Rules 2007, as amended. Parties must undertake a reasonable and proportionate search for relevant documents (meaning anything on which information is recorded), taking into account factors such as the nature and complexity of the proceedings, the volume of documents, the ease and cost to locate and retrieve the documents, and significance of the documents to the issues in dispute.

Parties must preserve relevant documents including ESI as soon as litigation is contemplated. Failure to do so may result in allegations of spoliation - the intentional destruction of relevant evidence in existing or anticipated litigation - and may expose a party to serious sanctions. The preservation obligation may extend to documents within a party's control, even where third parties hold them.

Following identification and review, parties exchange lists of documents and disclosure statements confirming compliance with their disclosure obligations. Documents are then made available for inspection unless inspection is withheld on recognised grounds such as privilege.

The use of AI and technology-assisted review

Disclosure frequently remains one of the most resource-intensive phases of litigation, particularly where large volumes of ESI are involved. ESI may comprise emails, instant messages, audio and video files, cloud-stored files, databases and even deleted documents. Given the broad definition of “document” and the increasing relevance of messaging and collaboration platforms, disclosure can quickly become difficult to manage.

E-discovery platforms help to handle these challenges by collecting, processing and de-duplicating data while allowing documents to be searched, indexed and organised for review. Reviewers can "tag" documents for relevance, privilege and specific issues, apply filters, analyse email threads and maintain audit trails throughout the review process.

Traditional e-discovery often relies on keyword searching and manual review. By contrast, modern platforms increasingly incorporate AI-enabled tools which use natural language processing and generative AI to identify concepts, understand context and prioritise critical material. Technology assisted review (TAR) uses supervised machine learning and predictive coding whereby a human reviewer codes a sample set of documents to train the system to prioritise documents within the data set. This can speed up the review and reduce the time spent on documents that are less likely to be relevant.

AI and TAR can improve efficiency by prioritising relevant material, grouping related documents, identifying themes, assisting with first-level review, translations and summaries. When used appropriately, they can enhance consistency, accelerate review and reduce costs, particularly in large-scale litigation.

However, TAR and AI-enabled tools are not perfect. They may produce false positives or false negatives, overlook context or nuance, and produce inaccurate outputs, including AI "hallucinations". Keep in mind that AI and TAR complement rather than replace legal judgment, strategic analysis and professional responsibility. Effective human oversight and quality control will remain essential.

Practical tips and common pitfalls

• Early preservation: implementation of preservation policies and identification of key date ranges, custodians and search terms early can help the e-discovery process run smoothly. Late preservation can lead to lost or unintentionally destroyed data

• Understand your data landscape: knowing which systems, databases and platforms are used can make it much easier to identify and collect relevant documents for review

• Proportionality: where large volumes of documents are involved, consider using e-discovery software and platforms with AI or TAR tools to assist with preservation, collection and analysis

• Protect privilege and confidentiality: email chains may contain both privileged and non-privileged content, attachments may have a different status from the covering email, drafts and internal comments may be overlooked and sharing documents with third parties can risk waiving privilege. Implement practical safeguards such as privilege keyword indicators and targeted quality control checks to protect this information

• Retain human review and legal analysis: decisions about privilege, redactions and confidentiality are legal judgment calls and should not be left to software alone. Human lawyers remain necessary for assessing context, relevance, privilege and evidential significance. Quality control is especially important where AI or TAR are used

Key takeaways

As businesses and individuals continue to communicate and store information digitally, e-discovery has become an integral component of modern litigation and investigations. For parties involved in Guernsey proceedings, preparation is essential. Identifying and preserving potentially relevant ESI at an early stage can reduce costs, minimise disruption and help avoid disputes about missing or incomplete evidence. Organisations with robust document retention policies, good governance over electronic communications and a strong understanding of their data landscape are likely to be better placed when disputes arise.

Emerging technologies, new communication platforms and the growing use of AI will continue to create both opportunities and challenges for litigants and practitioners. In this environment, a proactive and informed approach to e-discovery is increasingly important. By understanding their obligations and preparing early, parties can put themselves in the best position to comply with disclosure requirements and manage disputes efficiently in an increasingly digital world.
