Study contract law the way it actually happened.

Every case is a story before it is an authority.

Law arrives stripped down. A name, a citation, two lines of ratio, and instructions to hold it until May. You memorise it, you sit the exam, and by September it is gone.

The best lecturer I had spent twenty minutes on a woman who bought a smoke ball to keep the flu away and sued when she caught it anyway. I remember it. I could not tell you one thing from the slides that followed it.

I built LexCases to put that back. Most of what gets built next comes from students telling me what is missing. Here is what has changed so far.

Know the story and you do not need to memorise the name.

Law has always changed. LexCases shows you how.

Move through the moments that built the law you study, from the first written code to the cases you cite today.

c. 1754 BC Origins

The Code of Hammurabi

The first written law. Carved into stone in ancient Babylon, it set out the rules and their punishments in the open, so that every citizen could read the code that bound them.

  1. c. 1754 BC Origins

    The Code of Hammurabi

  • c. 1754 BC Origins

    The Code of Hammurabi

  • c. 451 BC Rome

    The Twelve Tables

    Rome writes its law down in public for the first time. Posted in the forum for all to see, the Twelve Tables became the root of the civil-law tradition that still shapes much of Europe today.

  • 1215 Limits on power

    Magna Carta

    No one stands above the law, not even the king. Forced on King John by his barons, the charter planted the seed of due process and the limits we still place on the power of the state.

  • 13th c. Common law

    The birth of precedent

    English judges begin to decide like cases alike. Out of that habit grew precedent, the principle that each judgment guides the ones that follow, and the doctrine LexCases is built to track.

  • 1932 Negligence

    Donoghue v Stevenson

    A snail in a bottle of ginger beer changed the law for everyone. The case created the modern law of negligence and the duty of care you owe your neighbour, whether or not you ever meet them.

  • 1948 to 1998 Rights

    The rights era

    Rights move from principle into hard law. From the Universal Declaration of 1948 to the Human Rights Act of 1998, protections for the individual were written into statute, and the law became a shield for the person against the state.

  • Yes. A model proposes candidate cases, then a second, separate pass checks each one before it reaches you. Anything it cannot confirm is dropped rather than shown, and nothing is substituted to fill the gap. Always verify against the primary court report before citation.

  • Summaries, key facts and 'legal effect' notes are AI-generated to give you a fast read on the case. Treat them as a starting point and confirm the ratio against the full judgment.

  • UK, Ireland, EU & ECHR, United States (federal + states), Canada, Australia, New Zealand, India, Singapore, Hong Kong, South Africa and several international courts. More are added regularly.

  • Free accounts get 20 tokens a week, and a search costs 3 of them, with up to 5 ranked authorities per search, including key holdings and concise reasoning. LexCases Pro lifts both limits and unlocks extended AI reasoning per authority, advanced comparison, and your full search history for €18.99 per month, or €189.99 per year (a saving of about €37). Every new monthly Pro subscription starts with a one week free trial.
