The U.S. Supreme Court has issued a ruling that effectively permits a president to allow millions of undocumented immigrants to enter the country but restricts the ability of a succeeding president to deport them. Critics argue that this decision creates a legal paradox where one administration can facilitate large-scale illegal immigration, while the next is legally barred from removing those immigrants without individual deportation trials, which are deemed impractical for millions. Lawmakers and commentators have expressed frustration with the ruling, stating it undermines immigration enforcement and the rule of law, and raises questions about the country's sovereignty and immigration system's functionality.
