The modern Texas corporate-law arc runs from a 1955 statutory baseline modeled on the Model Business Corporation Act through a 2003 unified-code consolidation, two Texas Supreme Court fiduciary-duty narrowings (2014, 2022), the 2023 institutional buildout, the 2024 Delaware redomiciliation catalyst, the 2025 three-statute reform cycle, and the December 19, 2025 Delaware Supreme Court reversal that doctrinally closed the loop. Twelve inflection points define the modern arc (1955 baseline; 2003 TBOC consolidation; 2014 Ritchie; 2022 Estate of Poe; 2023 H.B. 19/S.B. 1045 institutional buildout; January 30, 2024 Tornetta I; June 13, 2024 Tesla redomiciliation; 2025 S.B. 29; 2025 S.B. 1057; 2025 H.B. 40; December 19, 2025 Delaware Supreme Court reversal; and March 17, 2026 Gusinsky first federal enforcement of § 21.552). Each carries a statutory or judicial citation, and each is plotted in Figure 1.3
