39) as moot. While it is appropriate for the Court strike Lahti’s Reply on either of the bases offered by Consensys , the Court turns now to the more troublesome concern Consensys raises regarding fictitious case citations . This troubling discovery permeates the discussion pertaining to the remaining issues the Court must resolve.

This troubling discovery permeates the discussion pertaining to the remaining issues the Court must resolve. Consensys identifies four fictitious case citations in Lahti’s Reply. See Doc.

38, PageID 378. Indeed, these four supposed cases were cited by Lahti but appear to be fictitious; they cannot be found in the major commercial databases (Westlaw and Lexis).2 Additionally, two other cases were cite d with incorrect dates and reporter citations, and perhaps more 2 For the cases cited that were supposedly from the Sixth Circuit, the Court further confirmed that the Sixth Circuit issued no opinion with the identified caption or a similar caption on the identified date.

Every case in this record shares one cause: a citation reached a court without anyone opening it. What a citation gate is explains the mechanism that makes that impossible by construction; how to check an AI citation in five minutes is the manual version; the sanctions record is the essay this table grew out of.
