01 · Headline finding
Of 103 Texas Business Court opinions in the corpus, 63 (61%) resolved on a threshold ground — jurisdictional, procedural, or early-procedurali — without adjudicating an underlying claim on the merits.
The corpus is, 21 months in, predominantly a jurisdictional-doctrine corpus. The split here separates opinions for which a discrete claim adjudication is coded (merits-reaching) from those resolving only on procedural or jurisdictional grounds without reaching the underlying claim (threshold). Seven of the threshold-side opinions carry merits-shaped early-procedural postures (7 Rule 166(g) early-legal-issue rulingsi; 4 Rule 91a dismissalsi); they are coded threshold because the disposition did not adjudicate a claim on its merits. Bucketing convention: threshold = jurisdiction-only postures (remand, special appearance, plea to jurisdiction, removability, transfer) plus Rule 91a, Rule 166(g), and motions to dismiss; merits = every other posture (n=40). Hover any segment for the per-posture breakdown; click to filter the matrix below. The early corpus is a jurisdictional map, not a mature merits corpus.

Source note
The Texas Judicial Branch provides short staff descriptions for public convenience. Those descriptions are not part of the opinions, are not official statements of the court, and are not legal authority. Texas Judicial Branch, Business Court Opinions. The Codex uses staff descriptions only for intake; all final coding traces to PDF paragraph pin cites in the opinions themselves. The threshold/merits split reflects a coded ruling_bucket (threshold / merits / mixed) validated against the PDF, not a mechanical inference from an empty claims field.
Corpus snapshot & data coverage
Corpus snapshot: 2024 Tex. Bus. 1 through 2026 Tex. Bus. 40, last checked June 15, 2026.
No corpus-level inference is drawn from fields with low coverage. Petition-level pleaded-claim coverage requires docket / pleading backfill and is not complete unless an opinion row is marked “pleading verified.” Where a claim count appears, it distinguishes claims discussed or adjudicated in the opinion from pleaded causes of action in the underlying petition; a single opinion may carry multiple values on the former axis.
Methodology — full taxonomy and coding rules
Corpus universe. Every opinion published in the Texas Judicial Branch Business Court Opinions repository from October 1, 2024 through the last-corpus-check date above. Both full published opinions and memorandum opinions are included; the dataset distinguishes the two via the memOp flag.
Threshold vs. merits bucketing. An opinion is coded threshold when the disposition resolves on jurisdiction-only postures (remand, special appearance, plea to the jurisdiction, removability, transfer) or on Rule 91a / Rule 166(g) / motion to dismiss. Every other posture is coded merits. The split is computed live in the browser from the posture field; see bucketFor() in dashboard.js for the exact keyword list.
Ruling categories. Five buckets are recognized: granted, denied, mixed, remanded, other. The category is derived from the leading token of the ruling field with two fall-throughs (dismissed, substantive ruling) folded into other. The full ruling text is preserved verbatim and displayed in the matrix.
Primary-source linkage. Every opinion in the matrix carries a pdf_url that resolves directly to txcourts.gov. No CourtListener, Westlaw, Lexis, or other aggregator URL appears in the dataset (primary-sources rule).
Cell-level filtering. Every visualization element (iceberg segment, Sankey stream, heatmap cell, judge card, division-month cell, ribbon dot) is a click target. Clicking applies a filter to the matrix below and scrolls into view. Filter chips appear above the matrix and clear individually or via the Reset button.
Coverage caveats. The Court does not publish an order docket with file-date metadata; commencement-date coding for HB 19 § 8 questions traces to the opinion text plus the underlying state-court petition where verified. Petition-level pleaded-claim coding (which differs from the opinion's claim-adjudication coding) is incomplete and only displayed where flagged pleading verified.
HEADLINE FINDING · AS OF June 15, 2026
After 21 months of operation, the Texas Business Court has issued 103 substantive opinions across five divisions — but only 39% reach the merits, and 35% of the corpus is concentrated in just two judges (Whitehill, Bullard). Threshold rulings still outnumber merits-reaching opinions in the corpus to date.

02 · From courtroom to outcome
Division → procedural posture → ruling
Every published opinion traces a single path. It enters at one of the five operational divisions (1st · Dallas, 3d · Austin, 4th · San Antonio, 8th · Fort Worth, 11th · Houston), encounters a specific procedural posture (motion to remandi, plea to the jurisdictioni, Rule 91ai, summary judgmenti), and exits with a ruling. Stream width tracks opinion volume; stream color encodes the ruling category.
The corpus's largest single posture-disposition concentration: 19 of 29 remand-posturedi opinions (66%) resulted in the canonical disposition granted. Grants outnumber denials at remand by a wider margin than at any other posture in the corpus. Click any stream to filter the matrix below.
Streams thinner than two opinions are dimmed for legibility. Rare postures and rulings are grouped under "Other".
03 · Production over time
Opinion volume by division and month
Each cell is the number of opinions a division published in a given month. Darker = more opinions. The heatmap surfaces the corpus's two-track tempo: month-to-month volume is uneven, and the divisions do not stack on the same monthly cycle. Click any cell to filter the matrix to those opinions.
Volume builds through 2025; the 1st (Dallas) and 11th (Houston) divisions account for the densest cells, and the most recent month on the right is typically the largest as the court hits its stride. Cells with zero opinions appear muted; click any populated cell to drill in.
Cells colored on a 0–5+ scale; the Court has produced at most a handful of opinions per division per month. Months on the X-axis run from October 2024 to May 2026.

Divisions
The geographic units of the Texas Business Court. The 88th Texas Legislature created eleven divisions in HB 19; five — the 1st, 3d, 4th, 8th, and 11th — received funding and opened for filings on September 1, 2024. Tex. Gov't Code Ann. §§ 25A.002, 25A.003 (West 2025); HB 19, 88th Leg., R.S. (Tex. 2023). Across these five divisions the corpus contains 103 opinions (48 full published; 55 memorandum), October 2024 through June 2026.
Procedural postures
The specific motion or vehicle that put each opinion in front of the Court. These are the doctrinal levers — they determine the burden, the standard of review, and what the Court is actually deciding.
Rulings
"Granted" and "denied" carry posture-dependent operative consequences. A granted plea to the jurisdiction dismisses the suit for lack of subject-matter jurisdiction as filed; a granted motion to remand sends the action to the state district court from which it was removed. Posture and ruling must be read together. Of 19 granted remand motions in the corpus, 2 rest on § 25A.004(d) monetary-floor reasoning (Clean-Co under (d)(1); OWL Assetco 1 under (d)(2)); the remainder rest on commencement-date bars, counterparty status, or other statutory predicates.

Five doctrines, by share of substantive holdings in the first 21 months
Five doctrinal questions account for the largest share of substantive holdings in the corpus. Each is anchored in a specific statutory text, a controlling Texas Business Court opinion, and a practitioner-facing takeaway. Click any doctrine for plain-English meaning, the black-letter rule, the controlling TBC opinion, and the Bluebook authority.
04 · What was being argued, in what shape
Claims discussed or adjudicated × motion type
Across the merits-reaching opinions, this matrix shows which claims travel with which motion types. Rows are the claims discussed or adjudicated in each opinion (coded from court text, not from petitions); columns are the motions that produced the opinion. Darker cells = more opinions at that intersection. Heatmap counts opinion-claim pairs (an opinion deciding multiple claims contributes once per claim); the merits-reaching tile counts opinions. Pair total ≠ opinion total when an opinion adjudicates more than one claim.
On the heatmap's coding — claims on which an opinion's disposition actually operates on the merits — no single claim-by-posture cell dominates the early corpus. The largest cell is breach of fiduciary duty × other-merits rulings at 4 opinions, followed by breach of contract × summary judgment at 3. A broader pleaded-claim coding (claims present in the complaint but not necessarily reached on the merits) produces a larger contract footprint and is reported separately in the Methods section. Click any cell to drill into those opinions.
05 · Doctrine deep dive
Clean-Co Systems v. Enterprise Products Operating — the springing-aggregation question under § 25A.004(d)(1)
A Texas Business Court judge sent a $688,142 invoice fight back to district court, ruling that two decades of unrelated work under an umbrella service contract cannot be added together to clear the court's $5 million jurisdictional floor.
In 2003 a chemical-cleaning company, Clean-Co, signed an umbrella service agreement with an Enterprise Products affiliate. That agreement promised nothing on its own — work was ordered, one purchase order at a time, over the next 22 years. In 2025 Clean-Co performed work on a single purchase order; Enterprise didn't pay; Clean-Co sued in regular district court to collect about $688,000. Enterprise tried to move the case to the Texas Business Court — a specialized court for high-dollar commercial disputes — by arguing that because it had paid Clean-Co more than $7.8 million across all the purchase orders since 2003, the relationship as a whole cleared the court's $5 million jurisdictional floor.
Judge Grant Dorfman rejected that "add it all up" theory and sent the case back to district court. The point of the $5 million floor, he reasoned, is that the transactions giving rise to the lawsuit must themselves be big enough — not the parties' entire historical relationship. The 22 years of prior work spanned different facilities, different scopes, and possibly different Enterprise entities; only one purchase order was actually in dispute. None of the rest was in controversy. The decision is the first Texas Business Court opinion to reject this kind of "cumulative-payments-under-an-MSA" jurisdictional theory, and it tightens what defendants must show to keep a case in the specialized court.
The doctrinal hinge is § 25A.001(14)'s "series of related transactions" element, not the § 25A.004(d)(1) jurisdictional grant standing alone. The court signals a four-factor relatedness test as a matter of law: temporal span, scope congruence, facility/geographic congruence, and counterparty/affiliate continuity — applied against the transactions-in-controversy limitation the plaintiff advanced (P9, P11). The court reaches this result even on the deferential pleading-only standard of C Ten 31, LLC v. Tarbox, 2025 Tex. Bus. 1, ¶¶ 49–50 (3d Div.), and explicitly declines to make the hearsay ruling load-bearing (P8). The open question is what happens when temporal span is short, scope is congruent, and the same affiliated counterparty signs every order — Clean-Co does not foreclose aggregation in that fact pattern; it tightens it.
For a defendant invoking § 25A.004(d)(1) under MSA-pleading: (i) plead transaction-by-transaction relatedness with specificity, not a global cumulative-payment number; (ii) attach admissible business-records evidence of the cumulative figure (the Gold affidavit's failure is instructive); (iii) be prepared to address affiliate continuity across the MSA-signatory, the order-issuer, and the work-tasker (P7 n.6); (iv) consider pleading single-integrated-transaction in the alternative under Shell W. E&P (P10); and (v) anchor consideration value to time-of-contracting, not cumulative ex post performance, per Reed v. Rook TX, 2025 Tex. Bus. 34, ¶ 17 (P4 n.3).
In Clean-Co Systems v. Enterprise Products Operating, 2026 Tex. Bus. 32 (Dorfman, J., 11th Div., May 20, 2026), Enterprise argued that a "qualified transaction"i within the meaning of Tex. Gov't Code Ann. § 25A.001(14) (jurisdictional grant at § 25A.004(d)(1)) is established once cumulative payments under a long-running master service agreement clear the $5 million aggregate-value threshold, even when the single Purchase Order in dispute had an original not-to-exceed cap of $154,360 and a now-claimed invoice value of $688,141.87 after scope-of-work changes — an amount the plaintiff itself characterized as "less than one million dollars" (P9). The slider below illustrates how that aggregation would reshape the jurisdictional analysis.
Judge Dorfman granted remand on one dispositive ground: the historical purchase orders invoked by Enterprise do not constitute a qualifying "series of related transactions" under Tex. Gov't Code § 25A.004(d)(1) because they "span more than two decades, involve differing scopes of work, and were performed at diverse facilities" The Court separately sustained a hearsay objection to Enterprise's Oracle payment records. Judge Dorfman expressly rested the remand on the related-transactions ground; the opinion does not state, and does not depend on, the evidentiary ruling as an alternative ground. The holding is fact-bound rather than categorical. The Court did not announce a per-se rule against aggregation under § 25A.001(14); it held that the MSA history before it did not constitute "a series of related transactions" on the facts pleaded. Based on SMU CGI's survey of all 103 coded Texas Business Court opinions in the SMU CGI canonical corpus as of the most recent build, Clean-Co appears to be the first to reject the cumulative-payments-under-an-MSA aggregation theory advanced under § 25A.001(14)'s "series of related transactions" definition; the opinion itself does not claim first-impression status. The § 25A.004(d)(1) qualified-transaction floor governs this analysis; § 25A.004(d)(2)'s amount-in-controversy threshold is doctrinally separate and not at issue. Of 19 opinions in which the procedural posture is remand and the canonical disposition is granted, only two turn on a § 25A.004(d) monetary floor: Clean-Co (§ 25A.004(d)(1) qualified-transaction floor) and 2025 Tex. Bus. 30, OWL Assetco 1 v. EOG Resources (Bullard, J.) (§ 25A.004(d)(2) amount-in-controversy floor, addressing aggregation of joined-party claims under § 25A.004(i)). The remaining 11 turn on commencement-date bars (HB 19 § 8i), counterparty status (TBC jurisdiction over non-business-court parties), or other statutory predicates.
06 · Who is writing the doctrine
The bench at a glance
Ten Business Court judges have authored published opinions in the corpus's first 21 months. Each card shows that judge's opinion volume, grant rate, share of threshold-only rulings, and doctrinal signature — the procedural posture each judge has authored most often. Counts describe opinion output, not case difficulty, caseload, reversal risk, or judicial quality.
Whitehill (19) and Bullard (17) are the corpus's highest-output opinion authors; together they account for 36 of 103 opinions (35%). Bullard authored the leading opinions on HB 40 retroactivityi (2025 Tex. Bus. 47); Bullard also authored the AIC-aggregation remand in 2025 Tex. Bus. 30 (OWL Assetco 1 v. EOG Resources) under § 25A.004(d)(2), a separate qualified-transaction question from HB 40 retroactivity. Adrogué authored the leading opinions on the HB 19 § 8 commencement-date bar (2024 Tex. Bus. 8; 2025 Tex. Bus. 2 and 8); Andrews authored the leading opinions on Rule 166(g)i early-legal-issue rulings and on the Marathon Oil force-majeurei arc; Dorfman authored Clean-Co Systems.

Repeat-appearance ribbon
Fifteen captions account for 40 of 103 opinions (39%). Each horizontal lane is one caption; each dot is one opinion, positioned on a time axis from October 2024 to today and color-coded by ruling. "Caption" denotes a distinct adverse-party pairing as it appears on the face of the opinion; captions are not deduplicated by underlying business dispute.
Primexx Energy Opportunity Fund v. Primexx Energy Corporation generated five opinions across partnership, drag-along, fiduciary-duty, and personal-jurisdiction questions. Slant Operating v. Octane Energy Operating produced four. Marathon Oil v. Mercuria Energy America traces the Winter Storm Uri force-majeure arc across three opinions (two published, one memorandum). A small set of multi-opinion captions accounts for a substantial share of the corpus's published output to date.

FIGURE · OPINION-ISSUANCE VELOCITY
From a slow start to a 16-opinion month.
Twenty-one months in, the Texas Business Court’s opinion output is still climbing. The cumulative curve marks three inflection points: the first published opinion (Oct 2024), the first 9-opinion month (Dec 2025), and a record 16-opinion May 2026; June 2026 is in progress.
How to read. The red line is cumulative; the orange bars (lower band) are per-month issuance. May 2026 closed at 16 opinions—the largest single month to date; June 2026 is in progress. Twelve months elapsed before the corpus crossed 30 opinions; the next 30 came in five months; the most recent 30 in five months. A docket maturing as five divisions hit stride.
