Did Baxter dismiss U.S. v. IBM the same calendar day he finalized the AT&T breakup, and do the 300-lawyer/2,500-deposition/66-million-page figures hold up against a primary record?

Short answer the claims below support: Partially confirmed, with one important complication. Independent contemporaneous reporting (TIME, Jan. 18, 1982) corroborates that the Justice Department's announcement of the AT&T settlement and its dismissal of United States v. IBM happened on the same day — strengthening the same-day account beyond the two secondary retellings already in the vault (claim-baxter-dismissed-ibm-case-same-day-att-breakup-finalized). But "finalized" is ambiguous: the AT&T settlement was announced and signed on January 8, 1982, while the case itself was not judicially dismissed until August 24, 1982, per the Federal Judicial Center — over seven months after the IBM dismissal. Depending on which sense of "finalized" is meant, the same-day framing either holds (announcement-to-announcement) or breaks (dismissal-to-dismissal). The 300-lawyer/2,500-deposition/66-million-page figures remain unverified against a primary record: they trace to a single Wikipedia→Leary-2002-speech chain that could not be read this session (repeated 403s), and the one contemporaneous account located (TIME) describes a materially different picture — smaller trial-testimony figures for the DOJ's own case, with the 66-million-page figure attributed to separate private spin-off suits, not the government's suit itself.

Claim: The Justice Department announced the AT&T settlement and dismissed U.S. v. IBM on the same day — independently corroborated by contemporaneous reporting, not just retrospective accounts

Claim type: Quantitative (date-match) / historical.

TIME's contemporaneous account, published January 18, 1982 — roughly ten days after the events — states directly: "Later that same day, in New York, another Justice Department official appeared before a Federal District Court judge to declare that the Government was abandoning its 13-year effort to break up International Business Machines." This places the IBM dismissal announcement on the same calendar day as the Washington announcement of the AT&T settlement, independent of the two secondary accounts (Reason, 1982; Wikipedia, undated) already recorded in claim-baxter-dismissed-ibm-case-same-day-att-breakup-finalized. TIME does not state the exact calendar date itself (its own text only situates the events as "last week" relative to the Jan. 18 issue), so this source corroborates the sequencing but not an exact date in isolation; the "January 8, 1982" date is the consistent figure recurring across the secondary literature (Wikipedia, Reason-adjacent retrospectives, and multiple archive-title datelines observed but not read this session — see access_failures).

Sourcing floor check: This is a date-match claim, which the vault's floor classifies as quantitative and requires Tier 1-2 sourcing. TIME is a named-byline, contemporaneous, general-purpose news venue — closer to Tier 2 than the retrospective Tier 3/4 sources previously on hand, but still short of a primary court or DOJ record, which repeated attempts this session (Justia, CourtListener, DOJ's own case page, Washington Post, UPI) could not retrieve due to access blocks (403s) rather than the sources not existing. Flag stands: [unverified-quant — needs primary], but the corroboration is now stronger than before — an independent contemporaneous account, not just later retellings, supports same-day sequencing.

Claim: The AT&T case was not judicially dismissed until August 24, 1982 — over seven months after the January 8, 1982 announcement/signing, complicating what "finalized" means

Claim type: Quantitative (date).

The Federal Judicial Center's own historical account of the Bell System breakup states that the settlement terms (AT&T's divestment of its local operating companies, paired with modification of the 1956 consent decree) were agreed "in January 1982," but separately and explicitly states: "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." Other secondary reporting located this session (UPI archive titles from August 1982, unread — see access_failures) is consistent with a months-long gap between the January announcement and the case's formal court disposition, during which Judge Harold Greene's review process ran and modifications were incorporated.

This matters directly for the topic question: if "finalized the AT&T breakup" means the day Baxter's DOJ and AT&T signed and announced the settlement, that day (January 8, 1982) is the same day widely reported for the IBM dismissal. But if "finalized" means the day the AT&T case was itself judicially dismissed/closed — the same procedural category of event as the IBM dismissal — that happened August 24, 1982, which does not coincide with the IBM dismissal date at all. The popular "same day" narrative appears to rest on treating "announced the AT&T settlement" and "dismissed the IBM case" as comparable events, when the AT&T case's own formal dismissal came much later.

Sourcing floor check: Quantitative date claim; the Federal Judicial Center is a government judicial-history institution and clears Tier 2 on its own (institutional, high-method, though itself a historical narrative rather than a primary docket filing). No flag needed for the August 24, 1982 date itself, though it rests on a single source this session.

Claim: The 300-lawyer/2,500-deposition/66-million-page figures remain unverified against a primary record, and the one contemporaneous account located describes a different, non-matching picture

Claim type: Quantitative.

The combined "300 lawyers, 2,500 depositions, 66 million pages" figure — as a description of U.S. v. IBM itself — was not independently located this session beyond the same Wikipedia→Leary-2002-speech chain already identified in claim-baxter-dismissed-ibm-case-same-day-att-breakup-finalized. Leary's actual 2002 prepared remarks, the cited primary source for this figure, returned HTTP 403 on every URL variant tried (see access_failures) and could not be read.

TIME's contemporaneous account (Jan. 18, 1982) gives different, and differently-attributed, figures: "By the time the actual trial began in 1975, some 5,500 pages of testimony had been gathered, and more than a dozen other companies wound up filing spin-off antitrust actions of their own against IBM, producing 66 million more pages of documents." Read carefully, TIME attributes the 66-million-page figure to documents produced across the separate private spin-off suits filed by other companies against IBM — not to the government's own case file — which is a different claim from Wikipedia's phrasing that the "thirteen-year-old suit against IBM... had employed more than 300 lawyers and generated 2,500 depositions and 66 million pages of documents" as if all three figures describe the DOJ's suit itself. This is a real discrepancy, not just a rounding difference: either the 66-million-page figure was later generalized/conflated from the spin-off litigation to the main case in the Wikipedia/Leary retelling, or the two accounts are describing genuinely different scopes of litigation that happen to share a number. Neither this session's sources nor the existing vault note resolve which.

Sourcing floor check: Quantitative claim (three independent hard numbers). Per the floor, all three require Tier 1-2 sourcing; only Tier 4 (Wikipedia, citing an unread Tier-1-candidate speech) carries the combined figure, and the one contemporaneous account actually read (Tier 3) does not corroborate it as stated — it gives a different figure for a different scope. Flag: [unverified-quant — needs primary], now with an explicit noted discrepancy rather than silent corroboration.

Claim: Baxter personally characterized the IBM case as "without merit" in contemporaneous public remarks, ending a nearly 13-year DOJ suit by stipulated dismissal

Claim type: Historical / definitional (uncontested).

TIME quotes Baxter directly and contemporaneously: "Said Baxter in Washington of the IBM suit: 'The case is without merit and should be dismissed.'" This matches the wording ("without merit") already recorded from the Reason and Wikipedia accounts in claim-baxter-dismissed-ibm-case-same-day-att-breakup-finalized, now with a direct contemporaneous quotation attributed to Baxter himself rather than only a paraphrase. The case — United States v. IBM, filed January 17, 1969, in the Southern District of New York — is consistently described across every source located this session (TIME, Wikipedia, search-engine-surfaced case summaries) as ending via a government stipulation of dismissal rather than a trial verdict or settlement, roughly 13 years after filing.

Sourcing floor check: Historical/biographical claim describing settled, essentially uncontested facts (that Baxter dismissed the case, called it "without merit," and that this ended a ~13-year suit). Tier 3-4 is acceptable per the floor for this category; TIME's direct quotation clears even the higher bar comfortably for the "without merit" wording specifically.

Further leads

• Thomas B. Leary's full 2002 FTC prepared remarks, "The Essential Stability of Merger Policy in the United States" (Jan. 17, 2002) — the actual originating source Wikipedia cites for the 300/2,500/66M figures — every ftc.gov URL variant tried returned 403; worth a dedicated fetch attempt with different tooling or via the published version in Antitrust Law Journal 70 (2002): 105.
• Michael Weinstein's New York Times obituary of Baxter (1998-12-02) — the other Wikipedia-cited source, for the same-day claim specifically — not located or read.
• Washington Post, "U.S. Ends Antitrust Suits Against AT&T, IBM" (1982-01-09) — contemporaneous, would likely be strong enough to fully clear the Tier 1-2 floor for the same-day date claim; blocked by 403 this session.
• UPI wire "Government settles with ATT, drops IBM case," dated 1982-01-08 per its archive URL — dateline is suggestive of same-day filing but content unread (403).
• Washington Post / UPI, June–July 1982: Baxter was reportedly cleared of a conflict-of-interest allegation tied to prior consulting work for an IBM law firm (1975) and an IBM-funded academic fellowship (1969) — a separate, unverified thread about the dismissal's credibility, per "Baxter Cleared Of Conflict in IBM Dismissal," Washington Post, 1982-06-18 (unread, 403).
• Judge David Edelstein reportedly "angrily chastised" DOJ attorneys in his New York courtroom for Baxter's personal absence when the IBM dismissal was announced — surfaced via search-engine synthesis only, not independently verified against a readable primary or Tier 2 source.
• Truth on the Market, "The Ghosts of Antitrust Past: Part 2 (IBM)" (2020-02-03) — cites Robert Lande calling U.S. v. IBM "the largest legal case of any kind ever filed" and Robert Bork calling it "the antitrust division's Vietnam"; Tier 3, own citations (Washington Post, Wired, NYT) not verified against primary this session.
• Hagley Museum & Library holds two archival collections of IBM antitrust suit records (the Richard Thomas deLamarter collection and the Computer & Communications Industry Association collection) — a plausible route to primary case documents if this question is revisited.
• The IBM case's actual court opinion, United States v. International Business Machines Corp., 539 F. Supp. 473 (S.D.N.Y. 1982) — genuinely primary, located on Justia and CourtListener, but both returned 403/empty on every fetch attempt this session.

Entity candidates

• William Baxter — person — central figure in both dismissals; recurs across multiple vault notes on this topic and would anchor a page on the DOJ Antitrust Division's 1981-83 posture.
• Thomas B. Leary — person — former FTC Commissioner whose 2002 remarks are the ultimate cited (but unread) source for the case-size figures at the center of the unverified-quant flag.
• Judge Harold Greene — person — presided over the AT&T consent decree's judicial review and eventual entry.
• Judge David Edelstein — person — presided over U.S. v. IBM; reportedly displeased at Baxter's absence from the dismissal announcement.
• Christopher Byron — person — TIME reporter whose contemporaneous account is the strongest single source surfaced this session.
• United States v. IBM (1969-1982) — concept — worth its own case-history note; would anchor the "myth-generator" thread already flagged via claim-cullinane-called-ibm-unbundling-software-industry-origin-myth.
• United States v. AT&T (1982) / Modification of Final Judgment — concept — the companion case; the announcement-vs-judicial-dismissal distinction found here (Jan 8 vs. Aug 24, 1982) is itself a notable, under-told wrinkle.
• Federal Judicial Center — concept — a useful institutional source class for future U.S. antitrust/judicial-history research.
