Working Methods: Note S/2017/507 and Recent Reforms
How Note S/2017/507 codifies Security Council working methods, the penholder debate, and reform tracks from the Liechtenstein veto initiative to the 2024 Pact for the Future.
The Codification Project: From Note 507 to the Living Compendium
The Security Council's working methods are not codified in the Charter. Article 30 grants the Council authority to "adopt its own rules of procedure," and the Provisional Rules of Procedure (S/96/Rev.7, last revised in 1982) remain formally "provisional" more than seven decades after their first adoption in 1946. The substantive working methods have instead evolved through a layered corpus of presidential notes, the most consequential of which is Note by the President S/2017/507, issued on 30 August 2017 under the Japanese presidency and chaired by the Informal Working Group on Documentation and Other Procedural Questions (IWG), then led by Ambassador Koro Bessho.
S/2017/507 consolidated and superseded more than 80 prior presidential notes dating back to S/26015 (1993). It runs to 138 paragraphs organized under headings including Provisional Agenda, Implementation of Resolutions, Consultations of the Whole, Briefings, Penholders, Subsidiary Organs, and Cooperation with Troop- and Police-Contributing Countries. The Note is not legally binding in the Charter sense, but it operates as the authoritative reference invoked by elected members (E10) when challenging the procedural prerogatives of the Permanent Five (P5).
Penholdership, Transparency, and the Wrap-Up Session
The penholder system — by which a single delegation drafts resolutions on a given file — is the most contested working-methods question. Paragraph 80 of S/2017/507 states that "any member of the Council may be a penholder" and that "more than one Council member may act as co-penholders." In practice, the United Kingdom, France, and the United States hold roughly 80 percent of country-file penholderships. The E10's December 2022 Joint Statement, delivered by Norway and Mexico in their final month on the Council, demanded broader distribution; Albania and Brazil have since taken co-penholder roles on Colombia and Haiti respectively.
S/2017/507 also entrenches three transparency innovations. First, paragraph 38 commits the Council to hold "open" briefings as the default, reserving closed consultations for genuinely sensitive negotiation. Second, paragraph 116 institutionalizes the monthly "wrap-up session," pioneered by Singapore in 2001 and now routine. Third, paragraphs 50–55 require penholders to circulate draft resolutions in "blue" (the provisional printing) sufficiently in advance to allow E10 capitals to instruct — historically a 24-hour minimum, though Russia and China have repeatedly objected to compressed timelines, most visibly during the February 2022 negotiations on resolution 2623 (Ukraine), where the procedural vote under the Uniting for Peace framework moved the file to the General Assembly within 72 hours.
The Note further regulates Arria-formula meetings (paragraphs 65–69), an informal mechanism named for Venezuelan Ambassador Diego Arria, who convened the first such session in March 1992 on Bosnia. Arria meetings permit Council members to hear from non-state actors — NGOs, victims, special rapporteurs — outside the formal record. Since 2017, video-teleconference Arrias have proliferated; the 14 April 2022 Arria on the Bucha killings, co-hosted by France and Mexico, illustrated their utility for evidentiary briefing when a P5 member blocks formal consideration.
Recent reform pressure has centered on the veto. General Assembly resolution 76/262 of 26 April 2022 (the "Liechtenstein initiative") now requires the GA to convene within 10 working days of any veto cast in the Council, obliging the vetoing state to explain its position. While not a working-methods text in the strict S/2017/507 sense, it has reshaped the political cost calculus of vetoes — invoked seven times between April 2022 and the Russian veto on the DPRK Panel of Experts mandate in March 2024.
