Reg. §201.700. Initiation of proceedings for SRO proposed rule changes and for proposed 

NMS plans and plan amendments.

(a) Rules of Practice. For purposes of these Rules of Practice contained at 17 CFR 201.700-

701, the following Rules of Practice apply:

(1) Rule 103, 17 CFR 201.103 (Construction of Rules);

(2) Rule 104, 17 CFR 201.104 (Business Hours); and

(3) Rule 160, 17 CFR 201.160 (Time Computation).

(b) Institution of proceedings; notice and opportunity to submit written views.

(1) Generally. If the Commission determines to initiate proceedings to determine 

whether a self- regulatory organization’s proposed rule change or whether a proposed national 

market system (“NMS”) plan or a proposed amendment to an effective NMS plan (proposed 

NMS plan or NMS plan amendment hereinafter collectively referred to as “NMS plan filing”) 
should be disapproved, it shall provide notice thereof to the self-regulatory organization that filed 

the proposed rule change or to the NMS plan participants, as well as all interested parties and the 

public, by publication in the Federal Register of the grounds for disapproval under 

consideration.

(i) Prior to notice. If the Commission determines to institute proceedings prior 

to initial publication by the Commission of the notice of the self-regulatory 

organization’s proposed rule change or the notice of the NMS plan filing in the Federal 

Register, then the Commission shall publish notice of the proposed rule change or the 

NMS plan filing simultaneously with a brief summary of the grounds for disapproval 

under consideration.

(ii) Subsequent to notice. If the Commission determines to institute proceedings 

subsequent to initial publication by the Commission of the notice of the self-regulatory 

organization’s proposed rule change or the notice of the NMS plan filing in the Federal 

Register, then the Commission shall publish separately in the Federal Register a brief 

summary of the grounds for disapproval under consideration.

(iii) Service of an order instituting proceedings. In addition to publication in the

Federal Register of the grounds for disapproval under consideration, the Secretary, or 

another duly authorized officer of the Commission, shall serve a copy of the grounds for 

disapproval under consideration to the self-regulatory organization that filed the 

proposed rule change by serving notice to the person listed as the contact person on the 

cover page of the Form 19b-4 filing and shall serve a copy of the grounds for 

disapproval under consideration to the NMS plan participants by serving notice to the 

contact person for the NMS plan. Notice shall be made by delivering a copy of the 
order to such contact person either by any method specified in § 201.141(a) or by 

electronic means including email.

(2) Notice of the grounds for disapproval under consideration. The grounds for 

disapproval under consideration shall include a brief statement of the matters of fact and law on 

which the Commission instituted the proceedings, including the areas in which the Commission 

may have questions or may need to solicit additional information on the proposed rule change or 

NMS plan filing. The Commission may consider during the course of the proceedings additional 

matters of fact and law beyond what was set forth in its notice of the grounds for disapproval 

under consideration.

(3) Demonstration of consistency with the Exchange Act.

(i) The burden to demonstrate that a proposed rule change is consistent with the 

Exchange Act and the rules and regulations issued thereunder that are applicable to the 

self-regulatory organization is on the self-regulatory organization that proposed the rule 

change. As reflected in the General Instructions to Form 19b-4, the Form is designed to 

elicit information necessary for the public to provide meaningful comment on the 

proposed rule change and for the Commission to determine whether the proposed rule 

change is consistent with the requirements of the Exchange Act and the rules and 

regulations thereunder applicable to the self-regulatory organization. The selfregulatory organization must provide all information elicited by the Form, including the 

exhibits, and must present the information in a clear and comprehensible manner. In 

particular, the self-regulatory organization must explain why the proposed rule change is 

consistent with the requirements of the Exchange Act and the rules and regulations 

thereunder applicable to the self-regulatory organization. A mere assertion that the 
proposed rule change is consistent with those requirements, or that another selfregulatory organization has a similar rule in place, is not sufficient. Instead, the 

description of the proposed rule change, its purpose and operation, its effect, and a legal 

analysis of its consistency with applicable requirements must all be sufficiently detailed 

and specific to support an affirmative Commission finding. Any failure of the selfregulatory organization to provide the information elicited by Form 19b-4 may result in 

the Commission not having a sufficient basis to make an affirmative finding that a 

proposed rule change is consistent with the Exchange Act and the rules and regulations 

issued thereunder that are applicable to the self-regulatory organization.

(ii) The burden to demonstrate that a NMS plan filing is consistent with the 

Exchange Act and the rules and regulations issued thereunder that are applicable to 

NMS plans is on the plan participants that filed the NMS plan filing. In particular, these 

plan participants must explain why the NMS plan filing is consistent with the 

requirements of the Exchange Act and the rules and regulations thereunder applicable to 

NMS plans. A mere assertion that the NMS plan filing is consistent with those 

requirements is not sufficient. Instead, the description of the NMS plan filing, its 

purpose and operation, its effect, and a legal analysis of its consistency with applicable 

requirements must all be sufficiently detailed and specific to support an affirmative 

Commission finding. Any failure of the plan participants that filed the NMS plan filing 

to provide such detail and specificity may result in the Commission not having a 

sufficient basis to make an affirmative finding that a NMS plan filing is consistent with 

the Exchange Act and the rules and regulations issued thereunder that are applicable to 

NMS plans.
(c) Conduct of hearings.

(1) Initial comment period in writing. Unless otherwise specified by the Commission 

in its notice of grounds for disapproval under consideration, all interested persons will be given 

an opportunity to submit written data, views, and arguments concerning the proposed rule 

change or NMS plan filing under consideration and whether the Commission should approve or 

disapprove the proposed rule change or NMS plan filing.

(i) The self-regulatory organization that submitted the proposed rule change may 

file a written statement in support of its proposed rule change demonstrating, in specific 

detail, how such proposed rule change is consistent with the requirements of the 

Exchange Act and the rules and regulations thereunder applicable to the self-regulatory 

organization, including a response to each of the grounds for disapproval under 

consideration. Such statement may include specific representations or undertakings by 

the self-regulatory organization. The Commission will specify in the summary of the 

grounds for disapproval under consideration the length of the initial comment period.

(ii) The NMS plan participants may file a written statement in support of a NMS 

plan filing demonstrating, in specific detail, how such NMS plan filing is consistent with 

the requirements of the Exchange Act and the rules and regulations thereunder 

applicable to NMS plans, including a response to each of the grounds for disapproval 

under consideration. Such statement may include specific representations or 

undertakings by the plan participants. The Commission will specify in the summary of 

the grounds for disapproval under consideration the length of the initial comment period.

(2) Oral. The Commission, in its sole discretion, may determine whether any issues 

relevant to approval or disapproval would be facilitated by the opportunity for an oral 
presentation of views.

(3) Rebuttal.

(i) At the end of the initial comment period, the self-regulatory organization that 

filed the proposed rule change will be given an opportunity to respond to any comments 

received. The self-regulatory organization may voluntarily file, or the Commission may 

request a self-regulatory organization to file, a response to a comment received 

regarding any aspect of the proposed rule change under consideration to assist the 

Commission in determining whether the proposed rule change should be disapproved. 

The Commission will specify in the summary of the grounds for disapproval under 

consideration the length of the rebuttal period.

(ii) At the end of the initial comment period, the NMS plan participants will 

be given an opportunity to respond to any comments received. The plan participants 

may voluntarily file, or the Commission may request the plan participants to file, a 

response to a comment received regarding any aspect of such NMS plan filing under 

consideration to assist the Commission in determining whether such NMS plan filing 

should be disapproved. The Commission will specify in the summary of the grounds for 

disapproval under consideration the length of the rebuttal period.

(4) Non-response.

(i) Any failure by the self-regulatory organization to provide a complete 

response, within the applicable time period specified, to a comment letter received or to 

the Commission’s grounds for disapproval under consideration may result in the 

Commission not having a sufficient basis to make an affirmative finding that a proposed 
rule change is consistent with the Exchange Act and the rules and regulations issued 

thereunder that are applicable to the self-regulatory organization.

(ii) Any failure by the NMS plan participants to provide a complete response, 

within the applicable time period specified, to a comment letter received or to the 

Commission’s grounds for disapproval under consideration may result in the 

Commission not having a sufficient basis to make an affirmative finding that a NMS 

plan filing is consistent with the Exchange Act and the rules and regulations issued 

thereunder that are applicable to NMS plans.

(d) Record before the Commission.

(1) Filing of papers with the Commission. Filing of papers with the Commission shall 

be made by filing them with the Secretary, including through electronic means. In its notice 

setting forth the grounds for disapproval under consideration for a proposed rule change or a 

NMS plan filing, the Commission shall inform interested parties of the methods by which they 

may submit written comments and arguments for or against Commission approval.

(2) Public availability of materials received. During the conduct of the proceedings, 

the Commission generally will make available publicly all written comments it receives without 

change. In its notice setting forth the grounds for disapproval under consideration for a proposed 

rule change or a NMS plan filing, the Commission shall inform interested parties of the methods 

by which they may view all written communications relating to the proposed rule change or a 

NMS plan filing between the Commission and any person, other than those that may be withheld 

from the public in accordance with the provisions of 5 U.S.C. 552.

(3) Record before the Commission. The Commission shall determine each matter on 

the basis of the record.
(i) The record shall consist of the proposed rule change filed on Form 19b-4 by 

the self- regulatory organization, including all attachments and exhibits thereto, and all 

written materials received from any interested parties on the proposed rule change, 

including the self-regulatory organization that filed the proposed rule change, through 

the means identified by the Commission as provided in paragraph (d)(1) of this section, 

as well as any written materials that reflect communications between the Commission 

and any interested parties.

(ii) The record shall consist of the NMS plan filing filed by the plan participants, 

including all attachments and exhibits thereto, and all written materials received from

any interested parties on such NMS plan filing, including the plan participants, through 

the means identified by the Commission as provided in paragraph (d)(1) of this section, 

as well as any written materials that reflect communications between the Commission 

and any interested parties.

(e) Amended notice not required. The Commission is not required to amend its notice of 

grounds for disapproval under consideration in order to consider, during the course of the 

proceedings, additional matters of fact and law beyond what was set forth in the notice of the 

grounds for disapproval under consideration.
