Worked examples — the six classes

The Citation Record · §2.1 · companion to the scoring rubric

v0.1 · 8 September 2026 · draft, open for comment, not yet used to produce results

Every citation below states where it was checked and when. A page of examples that asserted citations without showing how they were confirmed would fail its own standard on the first line.

Two of these are not confirmed. They are printed anyway, with what is and is not established, because the limits are the part worth reading.

Lookups were run by resolve/ against CourtListener v4 on 8 September 2026. Each record is in the lookup journal at commit 0463301.

1Fabricated authority

Varghese v. China Southern Airlines Co., Ltd. — the fabricated authority at the centre of the Mata sanctions proceeding.

The fabricated citation is deliberately not reproduced. Printing it would give a known fabrication a citable paper trail in a document arguing against the propagation of unverifiable citations.

Checked
nothing was run; no citation is reproduced to run
Status
not verified, and not verifiable by this method

What this establishes: nothing about existence. A corpus miss would not establish fabrication either. §2.1.2's own boundary rule holds that "not in the corpus" and "does not exist" are different findings, so the strongest available statement is that no court has been identified as issuing such an opinion.

2Real authority, incorrect citation data

Brown v. Board of Education, 347 U.S. 483 (1954), rendered as 347 U.S. 486 (1955). The volume is right; the page and year are not.

Checked
CourtListener v4, cluster 105221
Retrieved
2026-09-08 18:47:41Z
Returned
Brown v. Board of Education, Supreme Court of the United States, filed 1954-05-17

What this establishes: the correct version is exact. Volume, page and year match, with no discrepancies recorded. The wrong version is a construction of this document and was not looked up.

3Real authority, misattributed holding

Ashcroft v. Iqbal, 556 U.S. 662 (2009), cited for a requirement to plead evidentiary facts sufficient to establish a prima facie case.

Checked
CourtListener v4, cluster 145875
Retrieved
2026-09-08 18:48:05Z
Returned
Ashcroft v. Iqbal, Supreme Court of the United States, filed 2009-05-18

What this establishes: the citation only. That the attributed proposition misstates the holding is an attorney judgment under §2.1.4 and is not settled by a lookup. Class 3 is never resolved mechanically.

4Real authority, superseded or no longer good law

Chevron U.S.A. Inc. v. Natural Resources Defense Council, 467 U.S. 837 (1984), cited for deference to a reasonable agency reading of an ambiguous statute, without noting that Loper Bright Enterprises v. Raimondo, 603 U.S. 369 (2024), overruled it.

Checked
CourtListener v4, clusters 111221 and 10600041
Retrieved
2026-09-08 18:48:29Z and 18:48:53Z
Returned
Chevron U. S. A. Inc. v. Natural Resources Defense Council, Inc., filed 1984-06-25; Loper Bright Enterprises v. Raimondo, filed 2024-06-28

What this establishes: both citations, and that the Loper Bright citation is final rather than a slip cite. It does not establish the overruling. CourtListener carries no treatment signal, so the relationship between the two is attorney judgment, not a field.

5Real authority, wrong jurisdiction or misrepresented weight

A query specifies a California Court of Appeal matter; the system returns a Ninth Circuit decision on the same issue and presents it as controlling.

Checked
nothing was run
Status
no case named

What this establishes: nothing, and nothing is claimed. The example is structural. It names no decision, so there is no citation to verify.

6The example that could not be verified

Mata v. Avianca, Inc., 678 F. Supp. 3d 443 (S.D.N.Y. 2023) — the sanctions proceeding the Class 1 example refers to.

Checked
CourtListener v4 by citation; by docket; govinfo USCOURTS
Retrieved
2026-09-08 18:47:29Z
Returned
not covered — CourtListener holds two opinions in volume 678 of F. Supp. 3d, at pages 1369 to 1371; page 443 is outside what it has
Docket
found — Mata v. Avianca, Inc., 1:22-cv-01461, S.D.N.Y., filed 2022-02-22, terminated 2023-07-07, via RECAP
govinfo
zero results for the docket number and zero for the case title

What this establishes: the case, court and docket are real. The reporter citation is not confirmed. A docket record and a reporter citation are different objects, and the second remains unverified. The most-cited AI hallucination sanctions opinion in the country is absent from the free federal repository and its reporter citation is outside the ground-truth corpus.

Objections are wanted, particularly from law librarians and practising attorneys, who would be the ones applying this. Write to jb@citationrecord.org.
