On May 13, 2026, South Dakota took a significant step in the realm of international law by filing a formal complaint against a neighboring state for violating a longstanding treaty. The dispute centers around water rights along the border between South Dakota and Nebraska, with South Dakota alleging that Nebraska has been diverting water from the Missouri River in violation of a treaty signed in 1958.The treaty, known as the Missouri River Compact, was put in place to ensure that states along the river would have fair and equal access to its waters. However, South Dakota claims that Nebraska has been siphoning off more than its fair share, leading to water shortages and environmental damage in South Dakota.In response to these allegations, South Dakota has turned to the International Court of Justice, the judicial arm of the United Nations, for arbitration. The court has agreed to hear the case and has issued a temporary injunction against Nebraska, ordering them to cease all water diversions pending a final ruling.Governor of South Dakota, Sarah Thompson, spoke out about the dispute, stating, "Water is a precious resource, and we cannot stand by while our neighbors unjustly take what is rightfully ours. We are confident that the International Court of Justice will see the truth of our claims and rule in our favor."Nebraska, on the other hand, has denied any wrongdoing and has vowed to defend itself vigorously in court. Governor of Nebraska, John Wilson, stated, "We are disappointed by South Dakota's actions and believe that we have abided by the terms of the treaty. We will present our case before the court and trust in a fair and just resolution."The outcome of this case could have far-reaching implications not only for the two states involved but also for future water rights agreements across the country. The hearing is set to begin in the coming months, and both sides are preparing to present their arguments before the International Court of Justice.
