“One of the few technological developments that genuinely succeeds in making a lawyer’s life easier

Sean Jones QC, 11KBW

…far more useful than I could have imagined.  I have since used it to track down some ‘difficult to find’ material.

Andria Lannon, DWP Legal

Case judgments can be time consuming to read. On JustisOne, discover the most cited passage of a case in seconds and link directly to the referencing case and paragraph number.

Bring together your resources

It’s difficult to know which database will have the case you’re looking for. JustisOne indexes content from over 120 platforms, including LexisLibrary, Westlaw, BAILII and ICLR so you can locate a case with a single search.

Easily identify relevant cases

When searching by subject term, JustisOne offers more depth and consistency than anywhere else. We’ve created a legal taxonomy with over 1.5 million terms to categorise every case, including reported cases and judgments directly from the courts, ensuring you can identify all relevant cases for the matter at hand.

Simple, powerful, affordable. See it for yourself

Distinguish case treatments

It’s vital to know where an authority has been considered and the subsequent treatment it has received. JustisOne displays all the related cases and statutes with treatments determined by our legally qualified editors, making it easier for you to establish the status of the law.

We use fourteen different treatment types (such as considered, applied, overruled or distinguished), to provide you with precise analysis.

Look to other jurisdictions

Our editors cross-reference cases to determine case treatments across all our coverage areas and jurisdictions, so you can find binding or persuasive cases from other jurisdictions with ease. This presents exciting new possibilities for comparative research.

Case relationships at a glance

The Precedent Map offers a visual representation of the relationships between cases. It helps you to understand the context of a case and find related cases at speed, in ways that are not possible through a direct search.

What makes Justis better

The making of something special

We launched JustisOne in 2016 and it is the combination of our two earlier products; Justis, the previous library and JustCite, our powerful citator. Launched in 1999, the previous Justis platform was widely regarded as one of the most intuitive online libraries at the time. It remains a trusted tool for thousands of practitioners and organisations worldwide. JustCite, launched in 2005, provides an index of legal material, with invaluable case relationships and citations metadata. Users would subscribe to these products individually or together. JustisOne now combines these products into a single, unified resource, to bring you a next-generation research platform.
