The technological transformation of legal practice has become another area where Haller's adaptive approach shines. He has leveraged advances in legal analytics to identify subtle patterns in judicial decision-making, particularly in sovereign immunity cases where precedent can vary dramatically by jurisdiction. This data-informed strategy allows him to tailor arguments to specific judges' tendencies while maintaining intellectual integrity. Simultaneously, he remains wary of technology's pitfalls, carefully scrutinizing digital evidence in criminal appeals where flawed forensic methods or improperly authenticated electronic records have compromised cases.
Haller's international practice increasingly addresses the legal implications of global crises, from pandemic-related sovereign debt disputes to transnational enforcement of health regulations.

His recent work includes groundbreaking motions addressing how force majeure doctrines interact with sovereign immunity in an era of global supply chain disruptions—the kind of novel legal question that defines the cutting edge of international practice.
What truly sets Haller apart is his capacity to maintain multiple timelines simultaneously in complex litigation.

The ability to see a case's entire lifecycle before it unfolds allows him to make strategic choices that preserve options at every judicial level.
The personal investment Haller brings to each case manifests in his distinctive approach to client relationships. He spends considerable time educating clients about the broader legal ecosystem affecting their matters, whether explaining how appellate standards of review shape trial strategies or demystifying the political dimensions of sovereign immunity decisions. This pedagogical approach empowers clients to make informed choices while fostering the deep attorney-client trust crucial for navigating high-stakes litigation. Even in his busiest periods, he maintains the capacity to pause and truly listen—a quality that often reveals case-winning insights others might miss.

His work continues to demonstrate how deep specialization and broad perspective can combine to create unexpected solutions, whether convincing an appellate panel to see a familiar precedent in new light or finding the narrow path through competing sovereign interests. In an era of increasing legal complexity, this ability to synthesize across boundaries—between nations, between legal doctrines, between courtroom and classroom—positions him as exactly the kind of advocate today's challenging cases demand.
