A bridge too far? Court splits on who controls the Kerch Strait

Back in 2016, after Russia started building a 19-kilometre bridge across the Kerch Strait to link mainland Russia with Crimea, Ukraine decided to challenge the move in an international court. Fast forward to April 22, but made public only on Monday, the Permanent Court of Arbitration in The Hague delivered a split decision: it agreed that Russia skipped proper environmental checks when it put up the bridge, yet it rejected most of Ukraine’s arguments that Moscow was trying to lock down the strait as its private waterway.

The judges did not order Russia to pay any compensation and told both sides to cover their own legal bills after a ten-year legal marathon. The case sits among a much broader set of lawsuits that Ukraine has filed since 2014, when Russia took control of Crimea and later launched a full-scale invasion in 2022. For Russia, the bridge is a vital supply line—linking fuel, food and other goods to Crimea, with the historic port of Sevastopol still hosting the Black Sea Fleet. What makes the ruling striking is not just the outcome but the gap between the environmental finding and the failure to recognize broader control claims. The court essentially said, “Yes, Moscow bent some sea rules, ” but stopped short of saying, “Yes, Moscow is illegally monopolizing the strait. ” That leaves the door open for future arguments about who really calls the shots in waters that sit between two countries with a tense history.
