A trial could be heard as early as 2025 to decide if the owner of the containership that brought down a bridge in Baltimore will face the full multi-billion-dollar impact of the world’s most costly maritime claim, according to a respected casualty lawyer.

More than 45 groups and individuals — from the US government to families moving home – have now lodged claims against the owner and operator of the 9,962-teu Dali (built 2005) after it hit and brought down the Francis Scott Key Bridge in Baltimore in March.

A week after the deadline to file claims, US federal judge James Bredar issued guidance on how he planned to run the case with a focus first on the shipowner’s bid to limit liability to less than $44m before turning to other issues, according to a memo.

Bredar, the chief judge of the US District Court for the District of Maryland, published the document setting out a series of steps to “efficiently and expeditiously” conclude the case being heard in Baltimore.

One experienced lawyer said the judge’s approach could mean that the trial on the attempt to limit liability could be heard as early as 2025 or 2026.

James Mercante, a partner at law firm Gallo Vitucci Klar, said: “Before this court order came down, I anticipated that it would be seven to 10 years before the hearing on limitation came to a head.

“But this judge has short-circuited all of that showing he's a no-nonsense federal judge and I would imagine the hearing on limitation would take place by the end of 2025 or early 2026.”

The question of limiting liability is key to the case with the US state of Maryland looking to claim damages from Singapore-based shipowner Grace Ocean and manager Synergy Marine for the $1.7bn needed to replace the bridge alone.

The state also wants damages for the impacts of the bridge disaster ranging from lost taxes to environmental costs.

But the owner and operator has sought to limit liability to less than $44m based on an 1851 US maritime law.

The bid is opposed by claimants including the city of Baltimore and the families of the six construction workers who died when the bridge came down.

They claim the ship was unseaworthy and should never have left port and that electrical faults that contributed to the crash were avoidable. A spokesman for the owner has said it looks forward to presenting its case in court.

If the shipowner and operator are successful, the comparatively small settlement would have a knock-on impact on the finances of the 12-strong group of protection and indemnity clubs and potential cost of future shipping reinsurance rates.

The judge has scheduled a hearing for 29 October to decide the outline timetable for the case and has told counsel for two of the claimants, the US government and the state of Maryland, to prepare a status report. He said the report should include a proposed timetable that was “detailed and precise”

“Only after resolution of the questions of whether petitioners are entitled to exoneration from or limitation of liability does the court anticipate setting deadlines” for other parts of the case, said the judge.

The judge has also urged claimants to band together to limit the number of people in court with nominated lawyers representing the dead workers, cargo claims, the government and private sector interests.

“With more than 45 claimants of various categories, judicial management of the case is going to be extremely important,” Mercante said.

Even if the liability part of the case is heard in 2025 or 2026, the case is still likely to run for years. Given the scale of the claims, whatever ruling emerges on liability is likely to be appealed, said Mercante.
