On September 23, 2025, the U.S. Court of Appeals for the District of Columbia Circuit set aside the key provision of the Federal Maritime Commission’s Final Rule on Demurrage and Detention Billing Requirements, 46 C.F.R. § 541.4, which allowed invoices for demurrage and detention to be issued only to contracting shippers and consignees. World Shipping Council v. Fed. Mar. Comm’n, 152 F.4th 215 (D.C. Cir. 2025). Why did the Court find this rule arbitrary and capricious? Who may now be charged for demurrage and detention? These questions are explored in this article.

When the Ever Given, a large container ship, became lodged in the Suez Canal in March 2021, it blocked one the world’s busiest maritime routes for several days. This incident led to a significant disruption in global trade, as hundreds of ships were delayed or forced to reroute around the southern tip of Africa instead of passing through the canal. Rerouting around the southern tip of Africa, known as the Cape of Good Hope route, can add approximately 7 to 10 days to a ship’s journey. This longer route increases fuel consumption and operational costs. Can the carrier recover the increased shipping costs from the charterer? This question is analyzed in this article.
