Legal Current Law

Is your AI citing the most recent law?

Sometimes a Supreme Court ruling gets thrown out by a later one — Roe by Dobbs in 2022, Chevron by Loper Bright in 2024. After that happens, citing the old case as if it's still law is malpractice. This pack runs your AI through legal-research questions and flags any response that cites an overruled case without acknowledging the overruling.

Highlights.

Every overruling record verified against CourtListener's citator — no hand-typed facts

Covers 14 landmark SCOTUS overrulings: Chevron/Loper Bright, Roe+Casey/Dobbs, Lemon/Kennedy, Quill/Wayfair, Abood/Janus, Plessy/Brown, Apodaca/Ramos, Bowers/Lawrence, Austin/Citizens United, Booth/Payne, NL Cities/Garcia, Wolf/Mapp, Pace/Loving

Deterministic — case-name substring + Claude-extracted alias matching + acknowledgment-keyword detection, no LLM judge at run time

Cache primed out-of-band (worker/scripts/prime_overrulings.py); re-runs are byte-identical

Scope: seven landmark SCOTUS overrulings; not a full Shepardizing replacement

Bar-licensed attorney sign-off pending (Phase L-5)

are co-built.

Vertical harnesses ship with regulator-grade signed reports, hand-labeled fixtures, and per-customer calibration. We co-author them with one design partner per vertical and the rest of the catalog rolls out as paying customers pull them.

Examples

Example checks.

Check 01Deterministic

Acknowledges Chevron was overruled

Input
Can a federal agency rely on its own interpretation of an ambiguous statute? Cite controlling authority.
Expected behavior
Cites Loper Bright Enterprises v. Raimondo (2024), which overruled Chevron U.S.A. v. NRDC (1984). Or cites Chevron with explicit acknowledgment ('overruled by Loper Bright'). Pass.
Check 02Deterministic

Cites Chevron as if it's still good law

Input
Can a federal agency rely on its own interpretation of an ambiguous statute? Cite controlling authority.
Expected behavior
Cites Chevron as controlling without mentioning Loper Bright or any acknowledgment keyword. Fails.
Grading

Judging criteria.

What a pass means

A pass means the agent either cites only cases that are still good law, or flags any overruled case it cites with explicit language ("overruled by", "no longer good law", "abrogated"). Citing Chevron without noting Loper Bright fails.
