The sudden resignation of Karim Khan as Chief Prosecutor of the International Criminal Court marked an abrupt end to a high-profile international career. Yet as the dust settles on allegations of serious misconduct that precipitated his departure, observers across the globe are grappling with a more nuanced question: will Khan's historical record be consumed entirely by the scandal, or might his earlier work command lasting recognition despite the dramatic conclusion?

Khan's tenure at the ICC was characterised by boldness and a willingness to pursue cases that many of his predecessors had avoided or deprioritised. His decision to pursue investigations into situations in Ukraine, Palestine, and Afghanistan represented a significant shift in the court's operational approach. These investigations signalled an institutional commitment to examining alleged crimes regardless of the political sensitivities involved, a departure from perceptions that the court had focused disproportionately on African nations. For many observers, particularly in the Global South, this geographical and political rebalancing represented a crucial evolution for an institution that had faced decades of criticism over its perceived biases.

The Ukraine investigation, initiated shortly after Russia's 2022 invasion, demonstrated Khan's capacity to mobilise the court's resources rapidly in response to contemporary conflicts. The decision to issue arrest warrants related to alleged war crimes in Ukraine showcased the ICC's potential to function as a responsive institution in real-time crisis situations rather than merely examining historical atrocities years after they occurred. This represented a meaningful departure from the court's traditional operating patterns and suggested an institutional evolution that many saw as overdue.

However, Khan's aggressive expansion of prosecutorial scope also attracted criticism from those who questioned whether the court possessed adequate resources and capacity to conduct credible investigations across such a diverse portfolio of situations. The simultaneous pursuit of cases spanning multiple continents, each involving complex geopolitical dimensions, raised practical questions about investigative depth and the court's ability to sustain rigorous legal proceedings. These concerns were not merely technical; they spoke to fundamental questions about the ICC's institutional sustainability and whether Khan's ambitions exceeded realistic operational capabilities.

The allegations that ultimately forced Khan from office centred on claims of serious misconduct, the details of which immediately overshadowed assessments of his prosecutorial record. The personal nature of the accusations meant that Khan's departure became inseparable from the scandal itself, a phenomenon that typically dominates public memory and media narratives surrounding departures from high office. The court's response to investigating these allegations would itself become a test of institutional integrity and governance standards that Khan himself had advocated for throughout his tenure.

For Southeast Asian observers and policymakers, Khan's legacy carries particular significance given the ICC's evolving relationship with the region. While no Southeast Asian nation is currently under ICC investigation, the institutional patterns established during Khan's tenure will shape future interactions between regional states and the court. His approach to Palestine and Afghanistan investigations carried implicit messages about the court's willingness to examine situations involving powerful nations and non-state actors, signals that resonate throughout Asia where concerns about international justice mechanisms' political neutrality remain pronounced.

Scholar assessments of Khan's impact have begun to emerge with considerable divergence in perspective. Some observers emphasise his role in expanding the court's geographic and thematic scope, viewing this as a necessary correction to historical patterns that had rendered the institution vulnerable to accusations of selective justice. Others argue that his prosecutorial ambitions, while laudable in principle, may have contributed to institutional strain that could ultimately undermine the court's credibility if investigations falter due to resource constraints or investigative complications.

The question of legacy is further complicated by the question of causation and institutional responsibility. Khan operated within a system shaped by the ICC's governance structures, state relationships, and resource limitations that predated his appointment. Isolating his specific contributions from these broader institutional contexts remains a challenge for historians and analysts attempting to apportion credit or blame for particular outcomes. The court's foundational tensions—between aspirations of universal justice and the political constraints that member states impose—existed long before Khan assumed office and will persist long after his departure.

Looking forward, Khan's tenure may ultimately be remembered as a pivotal moment when the ICC attempted a significant institutional recalibration, attempting to position itself as a more geographically balanced and contemporaneously responsive institution. Whether this reorientation survives his departure, becomes refined through his successors' approaches, or reverses entirely will significantly shape how historians ultimately characterise his impact. The allegations that ended his career may occupy considerable space in obituaries and initial assessments, but the substance of institutional change he championed or initiated may prove more durable than the personal scandal that occasioned his exit.

The international justice community watches carefully as the ICC navigates leadership succession and institutional accountability. Khan's replacement will inherit not only the investigations he initiated but also the question of how the institution reconciles commitments to expanded accountability with realistic operational capabilities. For nations across Southeast Asia and beyond, the court's next chapter will provide crucial signals about whether the ICC's attempted transformation toward more universal justice represents a lasting institutional evolution or merely a temporary deviation from established patterns.
