Westlaw Legal Case Coverage

Case Law Coverage

Starting coverage of state cases varies by state, but for most states, coverage goes back to the 1800s, and for some states even earlier.

Coverage of federal cases begins with 1789.

New cases are online within days, and sometimes hours, of their release by the courts.

KeyCite Status Flags

A KeyCite status flag lets you immediately know the status of a case, administrative decision, statute, or regulation.

  • A red flag warns that the case or administrative decision is no longer good law for at least one of the points of law it contains or that the statute or regulation has been amended by a recent session law or rule, repealed, superseded, or held unconstitutional or preempted in whole or in part.
  • A yellow flag warns that the case or administrative decision has some negative history but hasn’t been reversed or overruled; that the statute has been renumbered or transferred by a recent session law; that an uncodified session law or proposed legislation affecting the statute is available (statutes merely referenced, i.e., mentioned, are not marked with a yellow flag); that a proposed rule affecting the regulation is available; that the regulation has been reinstated, corrected, or confirmed; that the statute or regulation was limited on constitutional or preemption grounds or its validity was otherwise called into doubt; or that a prior version of the statute or regulation received negative judicial treatment.
  • A blue Hindicates that the case or administrative decision has some history.
  • A green C indicates that the case or administrative decision has citing references but no direct or negative indirect history or that the statute or regulation has citing references.
