736 F.Supp.3d 1364
Ct. Int'l Trade2024Background
- Byungmin Chae, proceeding pro se, challenged the denial of credit on Question No. 27 of the April 2018 Customs Broker License Exam (CBLE) by U.S. Customs and Border Protection (Customs).
- Passing the CBLE with a score of at least 75% is required to become a licensed customs broker; Chae's final adjusted score, even after multiple appeals, was below this threshold.
- Chae previously contested the denial of credit for certain exam questions in the U.S. Court of International Trade and the Federal Circuit ("Chae I"), both of which ruled against him after full review, with further appeal denied by the U.S. Supreme Court.
- The current suit was filed after all of these decisions, with Chae arguing that a vague regulatory definition undermined Question No. 27’s validity.
- The United States moved to dismiss the case on the grounds of claim preclusion (res judicata), arguing all issues were or could have been decided in the prior litigation.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether claim is barred by claim preclusion | New argument based on vagueness in regulation | Elements of claim preclusion are all satisfied | Claim preclusion applies; suit barred |
| Whether Plaintiff is entitled to credit for Q27 | "Customs territory" term was vague; should get credit | Same issue litigated previously; no new facts | No entitlement to relitigate or different outcome |
| Opportunity to raise issue in prior action | Did not specifically argue this exact vagueness | All related arguments could have been raised | Plaintiff had full opportunity to present all arguments |
| Whether new facts exist to justify new action | Implied that ambiguity was newly raised | No new facts or intervening law were presented | No new facts or law; therefore, claim preclusion applies |
