How can governance be legitimate when there is no world government? This question has driven the subfield of global governance in international law since the mid-twentieth century. The problem is not simply that states resist external authority; it is that the very idea of legitimate rule presupposes a political community that does not exist at the global level. Over seven decades, a sequence of frameworks has offered competing answers, each responding to the limitations of its predecessors while preserving, narrowing, or transforming key insights. The story of global governance in international law is one of persistent disagreement about the source of authority, the proper scope of regulation, and the role of law in a world of sovereign states.
The first systematic framework to address global governance after 1945 was Liberal Internationalism. Rooted in the conviction that international institutions could tame power politics, this approach saw the United Nations system, the Bretton Woods institutions, and the emerging human rights regime as the scaffolding of a new world order. Liberal Internationalists argued that states could bind themselves through treaties and organizations, creating a framework for cooperation that would gradually expand. The framework's distinctive contribution was its optimism about institutional design: if the right rules and organizations were put in place, states would find it in their interest to comply. Yet by the 1960s, critics noticed a gap between the institutional vision and actual state behavior. The Cold War paralyzed the Security Council, decolonization exposed the Western bias of many institutions, and economic inequality deepened. Liberal Internationalism had not solved the problem of authority; it had merely relocated it to institutions that lacked democratic accountability and enforcement power.
International Legal Process emerged in the 1960s as a more pragmatic alternative. Rather than assuming that institutions would automatically generate compliance, this framework focused on how law actually operates through persuasion, bargaining, and incremental decision-making. International Legal Process scholars studied the informal mechanisms—diplomatic exchanges, bureaucratic routines, dispute settlement procedures—through which states and international organizations manage conflict without a central authority. The framework narrowed the ambitions of Liberal Internationalism: instead of building a grand institutional architecture, it sought to understand the micro-processes that make governance possible. Its method was descriptive and contextual, tracing how legal arguments are deployed in real-world negotiations. This approach coexisted with Liberal Internationalism rather than replacing it entirely; many scholars used process theory to explain why some institutions worked better than others. But the framework's state-centered focus and its reluctance to question the underlying distribution of power left it vulnerable to more radical critiques.
Critical International Legal Theory emerged around 1990 as a direct challenge to both Liberal Internationalism and International Legal Process. Drawing on post-structuralism, Marxism, and post-colonial thought, critical theorists argued that mainstream frameworks had obscured the ways international law perpetuates hierarchy. The very categories of global governance—sovereignty, development, security—were shown to be products of historical power relations. Critical International Legal Theory did not offer a new institutional blueprint; instead, it insisted that any claim to legitimate authority must be interrogated for its exclusions. This framework transformed the subfield by making power visible where earlier approaches had seen only neutral rules or pragmatic processes. It absorbed some insights from International Legal Process—particularly the attention to informal practices—but turned them toward deconstructive ends. The critical turn did not displace earlier frameworks entirely; rather, it created a permanent tension between those who seek to improve governance institutions and those who question whether those institutions can ever be legitimate.
Feminist Approaches to International Law developed alongside the critical turn in the 1990s, sharing its suspicion of universal claims but adding a specific focus on gender. Feminist scholars showed that the institutions and concepts of global governance—sovereignty, security, the public/private distinction—are not gender-neutral. The state itself, they argued, is a gendered structure that excludes women's experiences and interests. Feminist Approaches engaged directly with governance debates by analyzing how international institutions design policies that affect women differently, from peacekeeping operations to trade agreements. This framework did not simply add women to existing governance models; it questioned the foundational assumptions about authority, representation, and legitimacy. Feminist scholars have remained in living disagreement with both Global Administrative Law and International Legal Constitutionalism, arguing that these frameworks often ignore how governance institutions reproduce gender hierarchies even when they adopt formal equality measures.
By the 1990s, the sheer proliferation of transnational regulatory bodies—from the World Trade Organization to private standard-setting organizations—created a new problem: how to hold these actors accountable without a global state. Two frameworks emerged in response, offering competing visions.
Global Administrative Law (GAL) argued that the solution lies in extending administrative law principles—transparency, participation, reason-giving, review—to global regulatory bodies. Drawing on domestic administrative law as a model, GAL scholars proposed that legitimacy could be achieved through procedural mechanisms rather than democratic representation. This framework preserved the institutional focus of Liberal Internationalism but narrowed it to procedural accountability. GAL's strength is its practical orientation: it offers concrete tools for improving the accountability of bodies like the Codex Alimentarius Commission or the World Bank Inspection Panel.
Global Legal Pluralism rejected this approach as too state-centric and too focused on formal procedures. Pluralists argued that global governance is characterized by overlapping, often conflicting legal orders—state law, international law, religious law, customary law, private regulation—that cannot be harmonized into a single administrative hierarchy. Instead of seeking procedural unity, pluralists advocated for mechanisms of mutual recognition, conflict-of-laws rules, and deliberative engagement across legal orders. This framework absorbed the critical insight that power is dispersed but rejected the critical conclusion that legitimacy is impossible. Global Legal Pluralism and Global Administrative Law remain in active competition today: GAL offers clarity and accountability, while pluralism offers flexibility and respect for diversity. Their disagreement is not merely academic; it shapes how scholars evaluate the legitimacy of institutions like the International Criminal Court or transnational arbitration regimes.
International Legal Constitutionalism emerged around 2000 as a direct response to the fragmentation that pluralism celebrated and that GAL tried to manage procedurally. Constitutionalists argued that global governance needs a normative hierarchy—a set of fundamental principles that override ordinary rules. Drawing on domestic constitutional theory, they proposed that certain values (human rights, the prohibition of aggression, environmental protection) constitute a global basic law that limits the authority of states and international organizations. This framework revived the liberal internationalist ambition of a unified legal order but grounded it in constitutional rather than institutional terms. International Legal Constitutionalism stands in sharp contrast to Global Legal Pluralism: where pluralists see fragmentation as inevitable and even desirable, constitutionalists see it as a threat to legal coherence and human rights protection. The two frameworks remain in fundamental disagreement about whether global governance needs a constitutional moment or whether it can function through pluralist accommodation.
Today, no single framework dominates the subfield. The leading approaches—Critical International Legal Theory, Feminist Approaches, Global Administrative Law, Global Legal Pluralism, and International Legal Constitutionalism—coexist in a state of productive tension. They agree on several points: that global governance is a distinct domain requiring theoretical attention, that legitimacy cannot be assumed from state consent alone, and that power operates through both formal and informal channels. But they disagree sharply on the source of legitimate authority. Global Administrative Law locates it in procedural fairness; Global Legal Pluralism finds it in mutual recognition across orders; International Legal Constitutionalism insists on normative hierarchy; Critical and Feminist approaches question whether any governance arrangement can escape the taint of exclusion and domination. The subfield's vitality comes from these unresolved disagreements. Students entering the field today inherit a conversation in which the foundational question—how can governance be legitimate beyond the state?—remains open, and each framework offers a partial but powerful answer.
