**The founding document of Major League Baseball's modern governance structure** and the document that created the Office of the Commissioner. Executed January 12, 1921, by the NL, AL, and their sixteen constituent clubs in the aftermath of the 1919 Black Sox scandal. Article I, Section 1 declares: 'The office of Commissioner is hereby created.' Article I, Section 6 names **Kenesaw Mountain Landis** as the first commissioner — the same Judge Landis who had presided over the 1915 Federal League case (the case files of which are also in this archive, as the NARA collection). The agreement is the textual ancestor of every subsequent version of the MLB Constitution (the post-2005 versions of which are in this archive). The original document is 1,230 words across nine articles. **Most consequential provisions**: (1) Article I Sec. 2(a) — the Commissioner's authority to investigate 'any act, transaction or practice charged, alleged or suspected to be detrimental to the best interests of the national game of base ball' (the 'best interests of baseball' clause, which becomes the doctrinal foundation of the 1978 Finley v. Kuhn ruling); (2) Article VII Sec. 1 — clubs and leagues 'severally waive all right of recourse to the courts as would otherwise have existed in their favor,' establishing the structural framework that the 1922 Federal Baseball SCOTUS exemption would then constitutionalize; (3) Article I Sec. 5 — seven-year Commissioner term at $50,000/year; (4) Article IX Sec. 1 — anti-amendment clause: 'no diminution or powers of the present or any succeeding Commissioner shall be made during his term of office,' the constitutional anti-coup provision.

Background

Every modern 'Commissioner's best interests of baseball' citation (Astros sign-stealing, Pete Rose, the steroid era, gambling discipline under Rule 21) ultimately traces to this document. Article I Sec. 2(a)'s 'best interests' language was carried into every subsequent version of the MLB Constitution; the Constitution chain in this archive (2005-06, ~2008 amendment, 2013/through-2018 amendment) all preserve essentially identical 'best interests' language traceable to 1921. The Black Sox scandal produced the Commissioner; the structural 'court-waiver' in Article VII Sec. 1 is the textual antecedent of the posture the 1922 Federal Baseball SCOTUS decision constitutionalized into the baseball antitrust exemption. The same Judge Landis who sat on the 1915 Federal League case (case files in this archive) and let it settle in favor of organized baseball became the first Commissioner six years later, with the powers his bench had effectively recognized codified into the 1921 Agreement. The Article IX anti-amendment clause — 'no diminution of powers... during his term' — is the structural reason Commissioners are functionally removable only at end-of-term or by mutual consent (e.g., the 1975 Kuhn-Seitz episode worked because Seitz served at the parties' pleasure as a neutral arbitrator, NOT as Commissioner).

Key provisions

  • Article I, Sec. 1 — 'The office of Commissioner is hereby created.'
  • Article I, Sec. 2(a) — Commissioner authority to investigate 'any act, transaction or practice charged, alleged or suspected to be detrimental to the best interests of the national game of base ball.' [Origin of the 'best interests' doctrine.]
  • Article I, Sec. 2(b) — Authority to determine 'what preventive, remedial or punitive action is appropriate.'
  • Article I, Sec. 2(c)-(d) — Final authority to hear disputes between major leagues and disputes 'to which a player is a party.'
  • Article I, Sec. 3 — Punitive action enumeration: public reprimand, $5,000 fine cap (club/league), suspension or removal of officers/employees, declaration of player ineligibility (no cap on duration).
  • Article I, Sec. 5 — Seven-year Commissioner term, $50,000 annual compensation, eligible to succeed self.
  • Article I, Sec. 6 — Kenesaw M. Landis named as the first Commissioner. Successor chosen 'by a vote of the majority of the clubs composing the two major leagues.' Anti-deadlock provision: after 3 months without election, the major leagues may request the President of the United States to designate a Commissioner.
  • Article II — Advisory Council (Commissioner + two league presidents), structured as a Commissioner-led body.
  • Article VII, Sec. 1 — 'The major leagues, and their constituent clubs, severally agree to be bound by the decisions of the Commissioner, and the discipline imposed by him under the provisions of this Agreement, and severally waive all right of recourse to the courts as would otherwise have existed in their favor.' [Source of the structural court-waiver doctrine.]
  • Article VII, Sec. 2 — All player contracts and major-league-officer contracts must contain a clause submitting the contracting parties to Commissioner discipline. [Origin of the modern UPC's submission-to-jurisdiction clauses.]
  • Article VIII, Sec. 1 — 'This Agreement shall remain in force for twenty-five years.' [The 25-year duration ends 1946 — see related history of the 1946 MLB Steering Committee on the wantlist.]
  • Article IX, Sec. 1 — 'No diminution or powers of the present or any succeeding Commissioner shall be made during his term of office.' [The Commissioner anti-coup provision.]

What's in the agreement

Nine articles, 1,230 words. Article I creates the Commissioner's office and names Landis as the first. Article VII waives the constituent clubs' right of recourse to the courts. Article VIII sets a 25-year duration. Article IX prohibits diminishing Commissioner powers during a term.

Why this matters

Every modern "best interests of baseball" exercise by the Commissioner — gambling enforcement under Rule 21, the Astros sign-stealing report, Pete Rose's lifetime ban — traces directly to Article I, Section 2(a) of this 1921 document. The current MLB Constitution chain in the archive (2005-06 true update, post-2005 ~2008 amendment, 2013 through-2018 amendment) all preserve essentially identical "best interests" language.

The same Judge Landis who let the 1915 Federal League case settle in favor of organized baseball (those case files are in this archive as the NARA collection) was then handed the powers his bench had effectively recognized — written into the 1921 Agreement. The Article VII court-waiver provision is the textual ancestor of the antitrust-immunity posture that the 1922 SCOTUS Federal Baseball decision constitutionalized.

Acquisition status

needs_review. Single online source: Doug Pappas's SABR transcription. Second-source confirmation needed — strongest route would be a direct check against the 1921 Reach Baseball Guide pp. 41-42 (the original primary source), which is public domain and likely available on Hathi Trust, Google Books, or the Library of Congress. The Hall of Fame Library would have the physical Reach Guide as well.
