See which cases carry weight

Courts cite courts. Every citation is one court pointing at an earlier decision and treating it as authority. Traced across the corpus, those pointers show which cases anchor a doctrine, which courts shaped it, and how far it spread. The citation network draws that structure.

From a case name to a map

Type a case name or a case ID above, or start from one of the famous cases listed there. Annlex finds the case, places it at the center, and draws the cases it cites alongside the cases that cite it, up to 50 of the most-cited in each direction. The counters beside the graph show how large each direction really is, so you can see how much of the network fits on screen. Citing cases are drawn in blue and cited cases in green; the toggle above the graph isolates either direction. Select any case in the graph for a summary and a link to the full opinion. If you do not have a case in mind yet, search the record first.

Built on the opinions themselves

The network rests on 71 million citation relationships extracted from the opinions in the Annlex library. A connection appears only where a citation written into one opinion was matched to another opinion we hold. What the graph leaves out is every citation that never resolved, which is worth remembering when a known reference is missing.
