A code-based corporate-governance architecture in a common-law country. The Texas Business Organizations Code consolidated a fragmented statutory regime in 2003; the 2025 reform cycle made it the center of a new strategy. This page maps the code, the common-law fiduciary baseline, the 2025 statutory hooks, and the Business Court and Fifteenth Court of Appeals that now adjudicate it.
HEADLINE FINDING · AS OF AUGUST 3, 2026
In the public-company governance areas mapped on this page, Texas now places more of the operating architecture directly into statutory text than Delaware typically does. The 2025 reform cycle codified a business-judgment rule, an elected derivative-threshold cap, an opt-in shareholder-proposal submission threshold, special-committee pre-certification, and governing-document forum authority for internal entity claims — against Delaware’s Court of Chancery tradition, which dates to 1792.

Some public commentary frames Texas largely as a change in forum. The statutory structure is different. Texas has moved several public-company governance rules into statutory text that Delaware often addresses through case law, and channels internal-entity disputes that meet the Business Court’s jurisdictional thresholds (Tex. Gov’t Code ch. 25A) to a specialized Business Court and a dedicated Fifteenth Court of Appeals rather than through Delaware’s Court of Chancery tradition (the Court of Chancery was established in 1792). Fiduciary duties remain principally common-law, but the common law now operates inside a much denser statutory envelope: forum-selection authority, jury-waiver authority, business-judgment-rule codification, derivative-standing thresholds, shareholder-proposal thresholds, books-and-records narrowing, and an express Texas-first source-of-law rule are all on the statute books as of 2025.1
This page maps that architecture in ten numbered sections plus a consolidated source list, with six inline figures, and ties every statutory and judicial citation in body text to a primary source: statutes.capitol.texas.gov for codified Texas statutes, capitol.texas.gov for enrolled bills, txcourts.gov for Texas judicial opinions, courts.delaware.gov for Delaware opinions, delcode.delaware.gov for the DGCL, and sec.gov for SEC filings. Practitioner commentary may appear in the prose as commentary but is never used as a primary citation target for a statute, case, or filing.2

METHOD · STANDING RULES
Four standing rules behind every statutory claim on this page.
V04 is a statutory reference, not a practitioner essay. The rules below govern every citation, every chart cell, and every claim about the 2025 reform cycle.
RULE 01
Primary sources only
Every statute links to statutes.capitol.texas.gov or delcode.delaware.gov; every enrolled bill to capitol.texas.gov; every opinion to txcourts.gov or courts.delaware.gov where the issuing court serves it, otherwise to an authoritative mirror (Justia, CourtListener) recorded in the link ledger.
RULE 02
Statute beats commentary
Where a 2025 reform statute is the operative authority, the cite is to the statute as enacted — not to a practitioner client alert or law-firm summary. Practitioner sources appear as commentary, never as primary citation targets.
RULE 03
Bluebook 21st throughout
Statutes follow TBOC § X.YYY form; cases follow Bluebook 21st short-form discipline with pin cites where available; signal words (see, cf., but see) carry their strict Bluebook senses.
RULE 04
Version-stamped
Each release of this page carries an explicit v#.# stamp and date in the hero block. The current edition reports the statutory state of Texas corporate law as of August 3, 2026 (frozen editorial as-of date; not auto-updated).
