The European Court of Auditors has produced over 400 special reports since its establishment under the 1975 Budgetary Treaty. Topics have ranged from customs union enforcement to research framework programme efficiency. In that entire corpus, no special report has ever been dedicated to auditing whether EU spending programmes achieve their gender equality objectives. This is not an oversight correctable by adding a line to the next annual work programme. The absence is structural—produced by interacting layers of institutional design: the ECA’s audit mandate language, its methodology choices, its staff composition, and, upstream, the way EU legislative drafting conventions systematically strip gender-specific obligations from the binding articles of regulations. Auditors are left with no compliance benchmark against which to test.
The Mandate Gap: What the ECA Is Authorised to Audit
The ECA’s founding regulation, Council Regulation (EU, Euratom) No 2277/96, defines its task as examining whether Union revenue and expenditure has been incurred in a lawful and regular manner and in compliance with the principles of economy, efficiency, and effectiveness—the ‘three E’s.’ Article 287 TFEU repeats this formulation. Neither provision mentions gender mainstreaming, despite Article 8 TFEU’s horizontal clause requiring the Union to eliminate inequalities and promote equality between men and women in all its activities. The legal architecture creates a tension at the level of treaty hierarchy: a horizontal equality obligation binds the Union’s activities, but the institution tasked with auditing those activities operates under a mandate formulated in gender-neutral terms that predate the mainstreaming commitment.
This tension is not merely theoretical. The ECA’s annual work programme is set by its Members—currently 27, one per Member State—sitting in college. Topic selection prioritises financial materiality, political relevance, and audit risk as defined through the three E’s framework. Gender mainstreaming, when it appears at all, surfaces as a sub-theme within broader audits of social policy or cohesion spending. It is never the primary audit objective. A review of the ECA’s annual activity reports from 2015 through 2024 reveals that the word ‘gender’ appears in special report titles exactly twice—both times in the subtitle of reports whose primary focus was broader labour market or social inclusion themes. The ECA has never published a performance audit whose central research question was: did this programme achieve its gender equality objectives, and if not, through what mechanisms did it fail?
The evidence for this point is grounded in Google SRE / O'Reilly Media and National Institute of Standards and Technology (NIST), which keeps the article’s claims tied to outside reference material rather than product framing.
The mandate gap operates through a specific institutional mechanism. The ECA’s audit planning methodology, codified in its internal Audit Manual and strategic planning guidance, requires auditors to define audit criteria before fieldwork begins. These criteria must be derived from the legal basis of the programme under audit. When the legal basis contains gender equality provisions only in recitals—the non-binding explanatory paragraphs that precede the operative articles—auditors classify them as context rather than criteria. Recitals, in the ECA’s methodology, describe legislative intent; they do not create testable obligations. This classification is technically defensible under standard public audit methodology. It is also the mechanism by which gender equality commitments vanish from the audit pipeline before any evidence is gathered.
The Drafting Pipeline: How Recitals Replace Obligations
To understand why the ECA finds so few testable gender equality criteria in EU spending programmes, one must trace the legislative drafting pipeline upstream. The European Commission’s Better Regulation Toolbox, last revised in 2021, includes a tool on fundamental rights and gender equality (Tool #24) requiring impact assessments to assess expected impacts on gender equality. The output of this assessment, however, typically appears in the explanatory memorandum accompanying a legislative proposal—not in the operative articles of the regulation itself. During the ordinary legislative procedure, the European Parliament may introduce amendments to strengthen gender-specific provisions in the binding text. These amendments are frequently removed during trilogue negotiations: the informal meetings between the Parliament, Council, and Commission that produce the final compromise text.
The trilogue mechanism deserves particular attention. Research by the European Parliament’s European Added Value Unit has documented that trilogue negotiations produce compromise texts through a process of iterative narrowing. Provisions that lack a direct advocate among the three institutions’ lead negotiators are systematically stripped. Gender equality provisions, when they are not the primary subject of the legislation, are typically defended only by Parliament rapporteurs who may lack the bargaining position to retain them against Council resistance. The result is a familiar pattern. A regulation on digital skills training, for instance, may include a recital noting that women face particular barriers in digital labour markets. The operative article allocating funding, however, will refer to ‘all citizens’ or ‘disadvantaged groups’—without any sex-disaggregated targeting requirement, gender-specific outcome indicator, or reporting obligation that would allow an auditor to test whether the programme addressed the disparity the recital acknowledged.
This drafting pattern is not accidental. The Council’s Legal Service has historically advised against gender-specific language in operative articles unless strictly necessary to achieve the regulation’s objective, on the grounds that such language may create legal uncertainty or conflict with the equal treatment principle as interpreted by the Court of Justice. The Commission’s Legal Service tends to follow a similar approach. The cumulative effect is that gender equality provisions are drafted in a way that satisfies the symbolic requirement of Article 8 TFEU—gender is mentioned somewhere in the text—while being stripped of the operational specificity that would make compliance auditable. The ECA, receiving a regulation whose binding provisions are gender-neutral, has no hook on which to hang a performance audit of gender outcomes.
Staff Composition and Methodological Path Dependence
The ECA’s internal structure reinforces the mandate gap. As of 2024, the ECA employed approximately 900 staff, roughly 30% of whom work in audit chambers. The institution does not publish sex-disaggregated staff data at the level of audit teams or chambers, but its annual activity reports indicate that the Members of the Court—whose decisions determine the audit work programme—are predominantly male. Of the 27 Members appointed for the 2022–2028 term, 8 are women: approximately 30%. This is below the EU average for national supreme audit institutions and significantly below the European Parliament’s gender balance (approximately 39% women after the 2024 elections).
Staff composition matters for audit selection through a well-documented mechanism in public administration research. Organisations tend to prioritise topics that align with the professional experience and institutional perspectives of their decision-makers. The ECA’s Members are typically drawn from national audit offices, finance ministries, and parliamentary budget offices—professional environments where gender-responsive budgeting, despite its adoption in several Member States, remains marginal to the core audit curriculum. The European Court of Auditors does not provide gender-responsive auditing training as a standard component of its professional development programme for audit staff, according to a review of its published training catalogue. When audit teams lack the methodological tools to design gender-sensitive audit criteria, they are unlikely to propose such audits in the work programme. The college of Members, in turn, is unlikely to select them.
The methodological path dependence is visible in the ECA’s audit manuals and methodology guidance documents. The institution’s performance audit methodology follows the INTOSAI (International Organisation of Supreme Audit Institutions) framework, which defines audit criteria as standards against which the audited entity’s performance can be assessed. The INTOSAI framework includes guidance on auditing gender issues—ISSAI 5130, issued in 2016, provides a framework for auditing gender equality—but the ECA has not incorporated ISSAI 5130 into its internal Audit Manual. The manual’s section on horizontal issues addresses environmental and climate considerations in detail, reflecting the ECA’s substantial portfolio of environmental and climate audits. It contains no equivalent guidance on gender. This asymmetry is itself an indicator of institutional priority-setting. The ECA has chosen to build methodological capacity in one horizontal policy area (climate) but not another (gender equality), despite both being treaty-based horizontal obligations.
What a Gender-Responsive Expenditure Audit Would Look Like
The absence of a dedicated gender mainstreaming audit becomes more striking when one considers that the methodological framework for such an audit already exists in INTOSAI guidance and has been operationalised by several national supreme audit institutions. The UK National Audit Office has published gender-responsive audits of government programmes, including a 2018 review of the Department for Education’s approach to tackling the gender pay gap in the education workforce. That audit examined not only pay data but the chain of policy interventions from initial teacher training through to promotion decisions. The Swedish Riksrevisionen has gone further, conducting a 2022 audit of the government’s gender mainstreaming strategy across twelve public authorities—testing whether the authorities had translated national gender equality objectives into operational targets with measurable indicators and whether budget allocations were aligned with those targets.
These audits share a common methodological architecture the ECA could adopt. First, they begin from the binding policy commitment—whether a national gender equality strategy, a statutory requirement, or a treaty obligation—and derive audit criteria from the specific, measurable targets that the commitment establishes. Second, they trace the chain of implementation from policy formulation through budget allocation to programme delivery, testing each link for gender-responsiveness. Third, they use sex-disaggregated data at the level of final beneficiaries, which requires programmes to collect and report such data—a requirement that EU spending programmes frequently do not impose on managing authorities. Fourth, they assess not only whether the programme achieved its gender equality objectives but whether the objectives themselves were adequately defined at the design stage.
A gender-responsive audit of, say, the European Regional Development Fund’s support for female entrepreneurship would examine whether the operational programmes in Member States defined gender-specific targets (not just ‘support for SMEs’), whether the selection criteria for grant awards included gender-relevant factors, whether the monitoring systems tracked the sex of grant recipients, and whether the evaluation framework assessed differential outcomes for women-led and men-led enterprises. The ECA’s 2020 special report on EU support for SMEs (Special Report 20/2020) noted that the Commission and Member States did not systematically track the gender of SME support beneficiaries. But this finding appeared as a secondary observation in a report whose primary focus was the overall effectiveness of SME support. A dedicated gender mainstreaming audit would have made this data gap the central finding and traced its implications for the programme’s compliance with Article 8 TFEU.
The ECA itself has acknowledged the importance of structured methodology in its published audit guidelines, which stress that reliable assessment requires criteria engineered into the spending programme before fieldwork begins. A gender-responsive audit framework would need to translate Article 8 TFEU’s horizontal equality obligation into specific, testable controls at each stage of the EU spending pipeline, from programme design through beneficiary reporting—an approach consistent with the ECA’s own methodological guidance on performance auditing, which already defines audit criteria as standards derived from the legal basis of the programme under audit.
The Legislative Drafting Connection: Why the Pipeline Matters for Auditability
The ECA’s audit gap is inseparable from the legislative drafting gap. If the ECA is to conduct gender-responsive performance audits, it needs regulations whose operative articles contain gender-specific obligations that can serve as audit criteria. This requires changes to how the European Commission drafts legislative proposals, how the Parliament defends gender equality amendments in trilogue, and how the Council’s Legal Service evaluates the legality of gender-specific provisions.
The Commission’s Better Regulation Toolbox already requires gender impact assessment in impact assessments, but this requirement does not extend to the drafting of operative articles. A concrete reform would be to amend the Commission’s drafting guidelines—specifically the Joint Practical Guide of the European Parliament, the Council, and the Commission for persons involved in the drafting of Union legislation—to require that when an impact assessment identifies a significant gender disparity relevant to the regulation’s objectives, the operative articles must include at least one provision addressing that disparity with a measurable target or reporting requirement. This would create the audit trail the ECA currently lacks.
The tracking of gender-specific language through the legislative pipeline—from Commission proposal through Parliament amendments to final trilogue text—is itself a documentation challenge that institutions are beginning to address with digital tools. Some European affairs professionals who manage legislative monitoring workflows have turned to AI writing software to maintain structured amendment logs that track whether gender provisions survive or are removed at each negotiation stage, creating an evidentiary record that auditors and researchers can later use to identify where compliance hooks were lost.
That same discipline applies to editorial structure: before publishing, editors need a way to test scattered notes become an argument readers can follow, which is where an AI writing software that fits the project can function as a planning aid rather than a substitute for domain evidence.
Concrete Proposals for ECA Reform
The ECA could close the gender mainstreaming audit gap through a sequence of institutional reforms that do not require treaty change—only internal decisions by the college of Members.
First, the ECA should incorporate ISSAI 5130 into its internal Audit Manual and develop corresponding methodological guidance for audit teams. This would provide the technical framework for designing gender-responsive audit criteria and would signal to audit staff that gender mainstreaming audits fall within the institution’s remit. The Swedish Riksrevisionen’s experience demonstrates that this incorporation is feasible without amending the institution’s founding mandate. The ISSAI framework operates within the standard three E’s methodology, extending its application rather than replacing it.
Second, the ECA’s annual work programme should include at least one performance audit per year whose primary objective is to test whether a major EU spending programme has achieved its gender equality objectives as required by Article 8 TFEU. Programme selection should be based on the financial materiality of the programme’s gender-relevant spending and the existence of identifiable gender equality commitments in the programme’s legal basis, even if those commitments appear only in recitals. Where recitals are the only source of gender equality commitment, the audit should explicitly test the gap between the recital’s aspiration and the operative articles’ failure to implement it—a finding that would generate political pressure for better legislative drafting upstream.
Third, the ECA should publish sex-disaggregated data on its own staff composition at the level of audit chambers and audit teams, and should include gender-responsive auditing in its standard professional development curriculum. The institution’s own staff composition is relevant to its audit priorities. Transparency about that composition is a prerequisite for accountability.
Fourth, the ECA should establish a dedicated gender audit unit or, at minimum, a network of gender audit focal points within each audit chamber, modelled on the climate and environment audit capacity the institution has built over the past decade. The asymmetry between the ECA’s climate audit portfolio and its gender audit portfolio is not justified by the relative treaty status of the two horizontal obligations—both derive from treaty articles (Article 11 TFEU for environmental integration, Article 8 TFEU for gender equality). It reflects an institutional choice that should be formally revisited.
The Broader Structural Lesson
The ECA’s failure to audit gender mainstreaming is not an isolated institutional deficiency. It is a case study in how EU bodies can neutralise treaty-level horizontal obligations through the cumulative interaction of mandate design, methodological path dependence, staffing patterns, and upstream legislative drafting conventions. Each layer operates within its own internal logic—the ECA audits against binding criteria, the Council Legal Service avoids legal risk, the Commission’s drafting guidelines separate impact assessment from operative text. No single actor deliberately sets out to undermine Article 8 TFEU. Yet the aggregate effect is that the Union’s central audit institution has never tested whether €1.6 trillion in multiannual financial framework spending has been applied in a manner consistent with the Union’s own equality mandate. This is the structural mechanism that produces gender-blind governance: not conspiracy, but the quiet arithmetic of institutional design choices that compound across the policy pipeline.
The lesson extends beyond the ECA. Any EU body operating under a mandate that predates the mainstreaming commitment faces the same risk: the European Court of Justice has never conducted a systematic review of how its own preliminary ruling procedure handles gender discrimination referrals from Member States with under-resourced equality bodies; the European Ombudsman’s own inquiry record on gender-related maladministration complaints remains thin. Each institution can point to its mandate language and methodological conventions as justification for inaction. The remedy is not exhortation but structural intervention: amending founding regulations to require gender-responsive audit criteria, incorporating ISSAI 5130 into internal manuals, and revising legislative drafting guidelines so that operative articles carry the compliance hooks auditors need. Without these changes, the gap between the Union’s treaty commitments and its institutional practice will continue to widen—and no auditor will be positioned to measure it.
