CommentaryAn Iranian court has announced that crude removed from the US-owned Advantage Sweet tanker has been sold for $36 million to $37 million. The proceeds, held by Iran’s judiciary, are intended to satisfy a damages judgment for 771 Iranians with epidermolysis bullosa (EB) over sanctions-related barriers to medical supplies. The vessel was released in 2024. For purposes of execution, oil has become money; the dispute can now follow the proceeds.
The seizure occurred in 2023, before the conflict that began in February 2026. The reported completion of the sale nevertheless reads like a preview. Within three weeks, Iran’s Persian Gulf Strait Authority expanded its blacklist in successive rounds—from 45 vessels to 56 and then to 77—threatening fines, detention, or cargo confiscation for breaches of its Hormuz transit rules. Houston’s US attorney has also confirmed Justice Department preparations for prize proceedings over vessels and cargo captured by American forces.
The sale, blacklist, and contemplated prize proceedings are not legal equivalents. Together, they expose the rival legal histories being assigned to ships, cargo, and proceeds. Iranian judgment execution, American civil forfeiture, and wartime prize each use a different rule to convert custody into value. The choice determines what must be proved, who may intervene, which earlier interests survive, and where the proceeds go. Capture supplies control. Value depends on a process that identifies the asset, ranks claims, and produces a title capable of surviving another court.
A Judgment Still Needs an Asset
The Iranian proceedings began with liability. According to the court’s public account, its judgment—said to exceed 100 pages—found that US restrictions had obstructed access to essential dressings and awarded material and punitive damages. UN mandate holders separately recorded reports that exempt medical shipments for EB patients faced serious delays attributed to licensing complexity and sanctions over-compliance. Injury, however, does not identify property available for execution.
Iran’s 2012 jurisdiction law rests expressly on reciprocity. Article 8 removes immunity from execution for property belonging to a covered foreign state, its officials, representatives, or dependent or controlled entities. The limiting word is “belonging.” Article 8 can remove immunity from property within those categories; it cannot by itself establish that a privately owned cargo falls within them. Reciprocity can explain domestic execution authority. It cannot compel recognition elsewhere.
The public account says the Tehran court conducted inquiries and determined that the cargo belonged to the US government. It does not disclose the chain of title supporting that conclusion or identify whether Chevron or another proprietary claimant received notice before sale.
Elsewhere, the same property has been described differently. The Advantage Sweet sailed under the Marshall Islands flag and was chartered by Chevron. In March 2026, a California insurance ruling described the vessel as carrying “Chevron crude oil” valued at approximately $51 million. That description arose in coverage litigation, not a final title adjudication, but it exposes the problem with calling the vessel American or treating every US connection as US government ownership. Even proof of Chevron’s title would not, without a further showing, establish that the cargo fell within Article 8’s covered categories.
Flag, charter, insurance status, and cargo ownership perform different legal functions. A flag determines the ship’s nationality. A charter allocates commercial use. An insurance policy may confer a right to recover for loss without conferring title. Cargo ownership depends on the transaction, including its documents and the contractual point at which title passed. One company may occupy several positions; none follows automatically from another.
The US Supreme Court confronted the same underlying distinction in Bank Markazi v. Peterson. Judgment creditors could pursue a specified pool of Iranian assets only after the statutory conditions were met, including a determination that Iran held equitable title or a beneficial interest. A judgment establishes what the debtor owes. Execution requires another proposition: the law makes this asset answerable for that debt. The Iranian plaintiffs’ medical injuries and the destination chosen for the proceeds do not establish that proposition. A compelling beneficiary cannot substitute for proof that the cargo fell within the execution statute.
Three Routes Move Value to Different Hands
The legal route matters because it begins distributing value before the auctioneer appears. Iran’s process treats the cargo as an executable asset of the United States and directs its proceeds to successful plaintiffs. American civil forfeiture instead treats property as connected to a statutory offense. Prize treats it as a wartime capture and, if condemned, directs the net proceeds to the Treasury. The route from custody to sale is distributive, not clerical.
Civil forfeiture has been Washington’s established instrument against Iranian oil. On September 14, federal prosecutors filed an in rem complaint seeking forfeiture of approximately $61 million in cryptocurrency alleged to be proceeds of black-market sales of sanctioned Iranian crude oil and petroleum products. The complaint has not been adjudicated. Its pleaded res is neither oil nor a tanker, but value allegedly traced from oil sales into digital assets. Supplemental Rule G requires a verified complaint and notice to potential claimants. In specified circumstances, it separately permits an interlocutory sale, after which the proceeds stand as a substitute res pending judgment. Under 18 USC §983, the government generally must establish forfeitability by a preponderance of the evidence; an innocent owner or qualifying bona fide purchaser may resist. Upon forfeiture, qualifying funds may be directed, in whole or in part, to the United States Victims of State Sponsored Terrorism Fund.
The contest between forfeiture and judgment enforcement is not hypothetical. In Estate of Levin, the D.C. Circuit held in 2025 that terrorism judgment creditors could pursue Iranian blocked funds despite an earlier federal forfeiture action over the same res. It rejected arguments that the earlier forfeiture proceeding and its license from the US Treasury’s Office of Foreign Assets Control (OFAC) automatically displaced the creditors’ Terrorism Risk Insurance Act remedies, but did not decide final priority. On remand, the district court reserved that question in March 2026, leaving the competing interests to be ranked after fuller briefing on final disposition.
Prize changes both the predicate and the distribution. Washington does not need to create a new tribunal: 28 USC §1333 already gives federal district courts exclusive original jurisdiction over prize cases. What the Justice Department must reconstruct is a procedure that has lain dormant. The prize chapter of Title 10, beginning at 10 USC §8851, applies to captures “during war,” language that could turn the conflict’s changing temporal status into a litigated question rather than a political label.
The absence of a formal declaration of war does not, by itself, disable prize law. In the Prize Cases, the Supreme Court held that an actual state of war may exist without one. The same decision made clear that neutrals could dispute a blockade’s existence and legal authority, and that condemnation for breach required notice. Modern litigants could also challenge the lawfulness of a particular capture, including whether a neutral vessel or its cargo was susceptible to seizure. The San Remo Manual, an influential restatement rather than a treaty, likewise treats vessel and cargo separately; a vessel’s neutral flag does not determine the character of everything aboard.
The US government’s shifting vocabulary makes timing more than academic. On April 30, an administration official said hostilities had “terminated” for purposes of the War Powers Resolution. The mid-April naval blockade nevertheless remained; it was later briefly lifted and reimposed. After renewed exchanges beginning August 30, Vice President JD Vance rejected the war label on September 3: major combat operations, he said, had lasted about six weeks, although fighting had since “flared up.” Six days later, President Donald Trump called it a “war” and predicted that it would end after the November midterm elections. Those descriptions do not settle §8851. An armistice suspends military operations without ending the state of war, and “hostilities” under the War Powers Resolution need not be coextensive with “war” under the prize statute. A court would still need a coherent account of when belligerent capture powers operated, especially for property taken during a lull or an arrangement suspending some operations but not others. No single word—war, ceasefire, or blockade—can do that work without the facts and applicable rule.
Prize may also alter earlier private interests. In the concerning steamer The Battle, the Supreme Court said capture as prize overrode prior liens. In The Hampton case, it was found that even a bona fide mortgage held by a loyal creditor did not take priority over the captor. Those Civil War decisions do not settle the status of modern secured interests or judgments that Congress made enforceable against Iran. A process promoted as a faster alternative to forfeiture might displace or subordinate the very victim claims that other federal statutes sought to protect.
Sale need not wait for every issue to be resolved. Under 10 USC §8865, a prize court must order sale after condemnation or earlier upon finding that the property is perishable, liable to deteriorate or depreciate, or disproportionately expensive to preserve. Section 8868 then sends the net proceeds of property ultimately condemned to the Treasury. The cargo can enter commerce while ownership, capture, and priority are still being litigated. Recent oil-price swings expose another allocation: sale replaces a volatile commodity with the price realized at one moment, while later market gains or losses travel with the cargo to the buyer. The physical cargo may disappear; what survives is a fund and the claims attached to it.
A Sale Must Survive Another Court
The missing participant in most accounts of maritime seizure is the buyer. A domestic order can authorize a sale without preventing a creditor from pursuing the property in another port, an insurer from asserting subrogation rights, or an alleged owner from tracing proceeds. A purchaser buys oil or steel together with the transaction’s jurisdictional history.
Nineteenth-century prize doctrine contains a striking distinction. In Cushing v. Laird, the Supreme Court explained that when a vessel is condemned as prize and sold by court order, the decree is conclusive as to the lawfulness of capture and the purchaser’s title. Yet the decree need not establish that the property originally belonged to the enemy: neutral property could also be condemned for conduct such as attempting to breach a blockade. Prize adjudication could thus clear the purchaser’s title without settling every antecedent dispute between private parties.
That effect depends on competence and procedure. In Rose v. Himely, the Supreme Court examined whether the foreign tribunal ordering condemnation had jurisdiction consistent with the law of nations. In Windsor v. McVeigh, it refused effect to a confiscation judgment entered after the claimant had been denied the opportunity to appear and defend. Control over the res can support in rem adjudication. Notice, jurisdiction, and an opportunity to be heard give its judgment a chance of traveling.
The most relevant modern model entered into force in February 2026. The Beijing Convention creates a cross-border system in which notice precedes sale, an official certificate records that clean title has been conferred, and an International Maritime Organization repository makes notices and certificates publicly accessible. Other States Parties must give effect to the resulting clean title; the Convention also provides for deregistration or transfer of registration and bars later arrest based on pre-sale rights extinguished by the sale, subject to a narrow public-policy exception.
The Convention does not govern the Advantage Sweet cargo. It concerns ships, not oil; neither Iran nor the United States appears among the listed parties; and its definition assumes that sale proceeds are made available to creditors, unlike prize proceeds directed to the US Treasury. It leaves priority and distribution to other law. It supplies the title half of a solution, not the claims half. The Convention treats clean title as an international system of notice, certification, and recognition, not a status created by attaching the word “judicial” to a sale.
What a Settlement Should Cover
A pause in military operations can stop the next capture without reversing the last one. It cannot restore cargo already sold, revive a lien extinguished by condemnation, or recover money already distributed. The first property task in any settlement is therefore classification: assets still held; assets sold with proceeds preserved; and assets sold after the proceeds have left the court’s control. Release may work for the first group. The second requires adjudication against a substitute fund. The third may leave only compensation between states or claimants.
Iran and the United States already possess a bilateral precedent for converting scattered litigation into an administered settlement. The 1981 Algiers Declarations terminated covered court proceedings, nullified attachments and judgments, placed assets in escrow, created a security account, and channeled claims to binding arbitration. They made the decisions and awards of the new Iran-United States Claims Tribunal final and binding, with awards against either government enforceable through national courts in accordance with domestic law. The tribunal still maintains pending cases. Its jurisdiction over private claims, however, was confined to claims outstanding in January 1981, followed by a one-year filing period. It supplies an institutional precedent, not jurisdiction over today’s seizures.
A property protocol attached to a ceasefire or peace agreement should adapt that precedent rather than pretend the old docket can be reopened. It should cover vessels, cargo, substitute proceeds, and sale-related claims arising during a defined period. Further distributions would stop, while perishable or depreciating property could be sold into neutral escrow. A public registry would identify each seizure, the asserted owner, known mortgages and liens, the legal basis for detention, valuation, sale, purchaser, and location of proceeds. Direct notice would go to registered owners, secured creditors, insurers with subrogation rights, judgment creditors, and other reasonably identifiable claimants.
A time-limited chamber would then decide attribution and priority under agreed rules. A defined filing period would close residual claims after adequate notice. Proprietary and secured interests would be separated from general unsecured claims; insurers would recover only to the extent of payment and subrogation; double recovery would be barred; and good-faith purchasers would receive protection only after notice and review. Once the chamber issued a clean-title certificate, unresolved claims would follow the escrowed proceeds rather than the asset. Flag, port, and financial states could join the recognition arrangement, because a bilateral agreement alone cannot command their courts.
The protocol would also require domestic authority. Dames & Moore v. Regan upheld the nullification of attachments and suspension of claims implementing Algiers in a narrow setting shaped by statutory authority, historical practice, and congressional acquiescence. It did not recognize plenary executive power to settle private claims. Legislation would provide the clearest authority for displacing or reprioritizing statutory judgment rights. An executive agreement alone could not override §8868’s command that prize proceeds be paid into the Treasury. Iran would likewise need rules capable of binding its courts and protecting certified sales.
This machinery may look remote amid recurring hostilities around Hormuz. It is already late for the oil taken from the Advantage Sweet. A sale has occurred, distribution has been ordered, and Iranian and US legal records describe the same cargo through incompatible accounts of entitlement. More captures would multiply that problem faster than courts can resolve it. By the time the fighting ends, the hardest property disputes may concern oil that no longer exists as oil.
