FINRA Rule 9100 is the series-level marker for the Application and Purpose division of the 9000 Code of Procedure — the organizational designation grouping the general provisions rules that apply universally across all Code proceedings. Its title — Application and Purpose — announces the subject matter of the rules that follow and signals their foundational character: these are not rules governing a specific type of proceeding but rules establishing the general procedural infrastructure that governs every type of proceeding throughout the Code. FINRA Rule 9100 has no operative text. Its FINRA.org page returns no rule text under The Rule tab — only the table of contents listing its child rules. The significance of FINRA Rule 9100 is architectural and substantive simultaneously: as an organizational marker it delineates the general provisions framework; as a reference in legal argument it carries the collective weight of every rule from FINRA Rule 9110 through FINRA Rule 9160 as a unified body of threshold procedural law.
FINRA Rule 9100 sits within the 9000 Code of Procedure as the first major division, positioned between FINRA Rule 9000's top-level marker and the first substantive rule FINRA Rule 9110. The Rule 9100 division was adopted as part of the original Code of Procedure through SR-NASD-97-28 effective August 7, 1997 and has been maintained as the general provisions organizational marker through all subsequent Code amendments.
The Rule 9100 Application and Purpose division organizes its rules into five functional clusters confirmed from the FINRA Rule 9000 table of contents and the FINRA Rule 9100 page directly.
FINRA Rules 9110 and 9120 — Application and Definitions — are the threshold rules establishing that the Code applies to all proceedings under the Rule 9000 Series unless a specific provision otherwise provides, and defining the thirty-five-plus defined terms used throughout the Code whose precise legal meaning determines the outcome of procedural disputes.
FINRA Rule 9130 — Service; Filing of Papers — and its seven subordinate rules FINRA Rules 9131 through 9138 — govern how every document in every Code proceeding is served on parties and filed with adjudicators. These rules define the authorized service methods for complaints, adjudicator-issued orders and decisions, party-to-party service, and the general methods and procedures for service; establish the filing procedures with adjudicators; define the form requirements for all papers; establish the signature requirements and certification effect of filing; and provide the time computation framework that governs every deadline in the Code.
FINRA Rule 9140 — Proceedings — and its subordinate rules FINRA Rules 9141 through 9148 — govern the procedural rights and restrictions applicable throughout all Code proceedings: who may appear and represent parties, how attorneys withdraw, the ex parte communication prohibition, the separation of functions requirement, the rules of evidence and official notice, motions practice, Hearing Officer authority to rule on procedural matters, and the general prohibition on interlocutory review with the sole FINRA Rule 9280 exception.
FINRA Rule 9150 — Exclusion From Rule 9000 Series Proceeding — governs the authority to exclude attorneys and representatives who engage in contemptuous conduct and cross-references FINRA Rule 9280's contemptuous conduct framework.
FINRA Rule 9160 — Recusal or Disqualification — is the universal impartiality standard establishing that no person shall participate as an Adjudicator in any matter as to which that person has a conflict of interest or bias or in which their fairness might reasonably be questioned, and identifying FINRA Rules 9233, 9234, and 9332 as the specific implementing rules for different categories of Adjudicators.
The most operationally significant provision in the entire Rule 9100 division is FINRA Rule 9110(a)'s universal applicability principle — the provision establishing that the rules in the Rule 9100 series apply to all proceedings under the Rule 9000 Series, unless a specific rule within the Rule 9000 Series provides otherwise. This principle makes the Rule 9100 general provisions the default procedural framework for every Code proceeding regardless of type. A disciplinary proceeding, an eligibility proceeding, an expedited proceeding, an exemption proceeding, and an automated systems grievance proceeding are all governed by the Rule 9100 service rules, filing rules, time computation rules, ex parte rules, separation of functions rules, and impartiality rules — unless a more specific provision within their respective series explicitly provides a different standard.
The universal applicability principle is one of the most important structural features of the entire Code and explains why the Rule 9100 general provisions are tested extensively on the Series 24 examination across multiple proceeding contexts.
FINRA Rule 9100 is tested on the Series 7 and Series 24 examinations as the organizational marker for FINRA's general provisions framework — the body of procedural rules that applies universally across all Code proceedings.
The key points to retain are these: FINRA Rule 9100 is the series-level marker for the Application and Purpose general provisions division — it has no operative text but organizes FINRA Rules 9110 through 9160 as the universal procedural infrastructure for all Code proceedings; the division contains five functional clusters — Application and Definitions covering FINRA Rules 9110 and 9120, Service and Filing covering FINRA Rule 9130 and FINRA Rules 9131 through 9138, Proceedings covering FINRA Rule 9140 and FINRA Rules 9141 through 9148, Exclusion from Proceedings covering FINRA Rule 9150, and Impartiality covering FINRA Rule 9160; FINRA Rule 9110(a)'s universal applicability principle makes every Rule 9100 provision the default standard for every Code proceeding unless a specific rule provides otherwise; and the Rule 9100 division was adopted as part of the original 1997 Code of Procedure and has been maintained as the general provisions organizational marker through all subsequent Code amendments.
