Citations you can stand behind in court.
Lawyers have been hauled up in court for filing cases an AI made up. A tool that invents citations is worse than no tool at all. So Miss Lucy is built the other way round, and the citations in a finished document are checked against real judgments before it reaches you.
Three checks, before a citation reaches you
Checked against real judgments
The reporter citations she writes are matched against 68,000 real Supreme Court and High Court judgments. A cite attached to a case we have no record of is blocked, not passed on to you.
Paragraph numbers checked, not guessed
A paragraph number has to exist in that judgment's own numbering. If we do not have the numbering for that judgment, she drops the paragraph number instead of making one up.
Checked on the documents she delivers
When Miss Lucy hands you a finished document — an opinion, a draft, a paper book — the citations in it are matched against the judgments, and a paragraph number she cannot confirm is dropped. In ordinary conversation she gives you the citation and the source so you can check it yourself before you rely on it.
A generic chatbot vs Miss Lucy
| When the citation is shaky | A generic chatbot | Miss Lucy |
|---|---|---|
| A citation we have no record of | Handed to you as fact | Blocked before you see it |
| A reporter cite that doesn't match the case | Slips through | Caught as a mismatch |
| A paragraph number | A guess that looks right | Checked, or dropped |
| The finished opinion or draft | Whatever it produced, as it is | Citations checked before the file reaches you |
The honest part
No system is perfect, and Miss Lucy never asks you to take a cite on trust. The checks run when she delivers a finished document. In ordinary conversation she gives you the source so you can confirm it yourself. The point is not to take your judgment away. It is to make sure you can check the citation in front of you before you spend that judgment on it.
