The Proportionality-Function Model for Global Human Rights Litigation

Thesis Abstract

This study addresses the fragmentation and inefficiency in global human rights litigation by proposing the Proportionality-Function Model (PFM), a framework that integrates proportionality assessment with functional force multipliers to optimize outcome relevance, legitimacy, and deterrence across diverse juridical contexts. The aim is to develop a theory-driven model that enables courts, international bodies, and civil society to calibrate litigation strategies according to proportionality thresholds and functional impact across varying jurisdictions, while preserving core human rights guarantees. Specific objectives include (1) delineating the conceptual intersections between proportionality analysis and functional effectiveness in human rights advocacy; (2) operationalizing a measurement scheme for proportionality sensitivity and function-performance across public, private, and transnational litigation settings; (3) testing the model’s predictive validity for case outcomes and normative legitimacy in a sample of global cases; (4) identifying contextual determinants (jurisdictional, political, and socio-economic) that modulate the PFM’s applicability; and (5) proposing policy and procedural procedures to harmonize cross-border litigations under the model. The study adopts a mixed-methods design, combining a comparative legal-empirical approach with qualitative thematic analysis. The population comprises Supreme and regional courts, international human rights bodies, and transnational advocacy organizations involved in at least one precedential case between 2000 and 2023 (n ? 300 cases). Stratified sampling yields a total of 120 cases for quantitative analysis, complemented by 40 in-depth interviews with judges, prosecutors, referees, and NGO counsel to capture interpretive and procedural nuances. Data collection employs codified case-law datasets, official court syllabi, and NGO impact reports, supplemented by semi-structured interviews and expert surveys. Instrument validity is enhanced through triangulation across case-law databases, institutional records, and respondent corroboration; reliability is ensured via inter-coder agreement (Cohen’s kappa > 0.78) for coding frameworks and pilot testing of interview guides. Quantitative analysis applies multilevel regression to assess the relationship between proportionality scales, functional impact indicators (policy change, enforcement, deterrence), and case outcomes, with robustness checks using fixed-effects models and sensitivity analyses. Qualitative data undergo thematic analysis to extract constructs related to legitimacy, stakeholder alignment, and procedural fairness, followed by matrix coding to integrate findings with the quantitative results. A joint display technique will synthesize quantitative results with qualitative insights to evaluate the PFM’s explanatory power and boundary conditions. Theoretical anchoring draws on Dworkin’s rights as trumps, Kantian cosmopolitanism, and legal realism, while incorporating modern theories of judicial legitimacy, effectiveness, and social construction of norms. The study also engages proportionality doctrine in constitutional, international, and comparative law to innovate a cross-jurisdictional analytical tool. Expected findings indicate that the Proportionality-Function Model enhances predictive accuracy for case success and normative acceptance by system actors when proportionate balancing is augmented by targeted function multipliers such as deterrence, compliance incentivization, and policy reform catalyzers. It is anticipated that higher alignment between proportionality reasoning and functional impact correlates with greater perceived legitimacy among courts and NGOs, as well as more durable policy changes. Contextual factors—such as constitutional design, treaty specificity, and domestic judicial culture—are expected to moderate the PFM’s effectiveness, producing clearly delineated boundary conditions and scenario-based guidance for practitioners. The study contributes to knowledge by offering a rigorous, operationalizable framework that bridges doctrinal analysis and empirical outcomes in global human rights litigation, enabling standardized cross-jurisdictional assessments and informing reforms in adjudicatory reasoning, procedural norms, and international advocacy strategies. It also provides a transferable methodological blueprint for future research on legal frameworks that seek to harmonize universal rights with local enforceability. The main conclusion posits that the Proportionality-Function Model, when calibrated to jurisdictional function profiles and audience legitimacy considerations, offers a robust and scalable approach to optimize both justice delivery and normative diffusion in global human rights litigation. Recommendations include the development of an open-access PFM toolkit for courts and NGOs, training modules for proportionality assessors, and policy guidelines to standardize cross-border litigation protocols while preserving local autonomy and context sensitivity.
