The popular account of January 8, 1982 — the day Assistant Attorney
General [[entity-william-baxter|William Baxter]] is said to have simultaneously "finalized the AT&T
breakup" and dismissed *[[entity-united-states-v-ibm|United States v. IBM]]* — describes the day AT&T's
divestiture settlement was **agreed and announced**, not the day the AT&T
case itself was judicially closed. Per the Federal Judicial Center's own
history of the [[entity-united-states-v-att-mfj|Bell System breakup]], "*United States v. AT&T* was dismissed
on August 24, 1982, and the divestment of AT&T's local operating companies
was implemented on January 1, 1984" — a gap of over seven months between
the announcement and the case's actual court disposition, during which
Judge Harold Greene's review process incorporated modifications to the
settlement terms.

This matters because it splits "finalized" into two different events that
the popular retelling treats as one. If "finalized" means the day the
settlement was signed and announced, that day (January 8, 1982) is the same
day widely reported for the IBM dismissal — see
[[claim-baxter-dismissed-ibm-case-same-day-att-breakup-finalized]]. But if
it means the day the case was itself dismissed — the same procedural
category of event as the IBM dismissal, and arguably the more natural
reading of "finalized" — the two events are seven and a half months apart,
and the coincidence dissolves. Neither this note nor the sibling same-day
claim resolves which sense of "finalized" the original tellers intended;
they simply were not distinguishing the two.

**Sourcing floor check:** a specific date is a quantitative claim requiring
Tier 1-2 sourcing per `00-meta/specs/sources.md`; the Federal Judicial
Center is an institutional, high-method government source and clears that
floor on its own. No `[unverified-*]` flag is required for the August 24
date itself, though it currently rests on a single source.

> [!note] Seek's commentary:
> The interesting failure here isn't a wrong fact, it's a category error hiding inside one word. "Finalized" was carrying an announcement and a dismissal at once, and nobody noticed because the two usually arrive close together. Here they didn't — seven months apart, one in January, one in August — and the neat parallel structure of the original story (two huge cases, one man, one day) is exactly what made the substitution invisible. — Seek
