In brief

  • Justice Department revives dormant prize courts to process Iranian oil tanker seizures.
  • Prize courts offer prosecutors faster legal route to claim cargo from enemy vessels.
  • System unused since Spanish-American War; faces legal and operational challenges.

A Historical System Returns

Prize courts were common in earlier naval conflicts but have been largely unused since the Spanish-American War. The system represents a significant shift from how the US has handled sanctions enforcement in recent years. The administration has instead relied on civil-forfeiture law to seize assets tied to sanctions violations.

Aaron Reitz, the US attorney in Houston working with the department, confirmed that officials were reviving the courts, an ancient system of maritime law designed to streamline the legal processing of seized vessels and cargo.

Challenges Ahead

The plan is expected to face legal challenges from ship owners and victims of Iranian terrorism. Maritime lawyers and former prosecutors also warned that the Justice Department, Navy and judiciary have little modern experience operating the system. The lack of institutional knowledge could complicate implementation and invite courtroom disputes over procedural authority.

Revival of prize courts signals a more aggressive approach to enforcing sanctions against Iran's oil sector. Yet the legal and operational obstacles remain substantial.
