The U.S. Court of International Trade has dismissed an appeal from Byungmin Chae, who challenged the denial of his customs broker license. The ruling, issued on July 8, 2026, affects Chae's ability to operate as a customs broker, a position requiring a passing score on a specific examination. The court's decision highlights the importance of adhering to legal procedures and deadlines in administrative appeals.
Chae's case centers on his dissatisfaction with the results of the April 2018 Customs Broker License Examination (CBLE), administered by U.S. Customs and Border Protection (Customs). The court's ruling means that Chae cannot pursue further claims regarding the denial of credit for a specific question on the exam, which he argued was unfairly graded.
Background
Byungmin Chae, a resident of Omaha, Nebraska, has been attempting to obtain a customs broker license for several years. To qualify, applicants must pass the CBLE, which consists of 80 questions. A score of at least 75 percent is necessary to pass. Chae initially scored 65 percent on the exam, prompting him to appeal to Customs’ Broker Management Branch (BMB).
After his appeal, Customs awarded Chae credit for two questions, raising his score to 67.5 percent. He then appealed to the Executive Assistant Commissioner, who granted credit for three additional questions, bringing his score to 71.25 percent. However, this score still fell short of the required passing mark.
Chae first filed a lawsuit in March 2020, challenging the denial of his license application. The U.S. Court of International Trade allowed him to amend his complaint after initially dismissing it for lack of subject matter jurisdiction. In subsequent rulings, the court upheld Customs' decisions, stating they were supported by substantial evidence.
The Ruling
In the latest ruling, Judge Timothy M. Reif granted the United States' motion to dismiss Chae's complaint. The court found that Chae's claims were barred by the doctrine of claim preclusion, which prevents parties from relitigating issues that have already been decided in a final judgment.
The court ruled, "Claim preclusion bars not only claims that were actually litigated but also claims and legal theories that could have been raised in the prior action."
The court noted that Chae's current appeal was his third challenge regarding the same issue, specifically focusing on Question No. 27 from the 2018 exam. The judge emphasized that Chae had previously raised similar arguments and had ample opportunity to present his case in earlier proceedings.
Reif's opinion also addressed Chae's argument that a recent legal decision constituted new evidence that could alter the outcome of his case. The court dismissed this claim, stating that the legal change did not qualify as newly discovered evidence and that Chae could have raised the argument in his previous cases.
Impact
This ruling has significant implications for Chae, who has now exhausted his legal options regarding the customs broker license denial. The court's decision reinforces the importance of timely and thorough legal arguments in administrative appeals. It also serves as a reminder to applicants that they must carefully follow the legal process and deadlines when contesting decisions made by government agencies.
Moreover, this case illustrates the challenges faced by individuals navigating the complexities of administrative law and the judicial system. The court's adherence to the doctrine of claim preclusion emphasizes the need for litigants to present all relevant arguments in their initial filings.
What's Next
Chae's options for appeal are limited following this ruling. He may not have further recourse in the U.S. Court of International Trade, as the court has dismissed his claims. There is no indication of any related cases pending that could affect this outcome. The court's decision appears to be final, barring any extraordinary circumstances that could warrant reopening the case.
