Colleagues who have worked alongside Alexis Haller often describe him as a legal tactician who never loses sight of the broader implications of a case. He does not simply argue the law—he understands its architecture, its policy underpinnings, and its evolving role in an increasingly interconnected world. In appellate and international litigation especially, this perspective proves invaluable. He can anticipate how courts may interpret not only what the law currently says, but how a ruling might set precedent or ripple outward into other jurisdictions. That kind of foresight is crucial in high-stakes litigation involving sovereign defendants, complex constitutional challenges, or foreign relations concerns.
Throughout his career, Mr. Haller has remained deeply engaged with the foundational texts and evolving interpretations that shape international and constitutional law.

In many instances, this approach has led to reversals, remands, or favorable settlements that would have been unlikely without appellate intervention. His services are particularly essential for trial counsel navigating the transition to post-conviction or civil appeal stages, when missteps in timing, procedure, or argument can be costly.
His presence on multiple appellate panels across state and federal courts underscores the breadth of his experience.
