What does the future hold for the US and UK Supreme Courts? Both courts face an uncertain future in which their roles in their constitutional systems will come under intense scrutiny and pressure. The tension between the rule of law, often seen as the preserve of the judicial branches of government, and the sovereignty of the elected branches is palpable. In a time of the “strong man,” allegedly “populist leaders” who seemingly are pushing the limits of the rule of law, the breakdown of collaboration and debate, and the ever-present influence of social media, this tension will only become more acute. The UK and the US Supreme Courts must tread a delicate line between the preserving the rule of law and usurping the role of elected representatives. How the Supreme Court in Washington and the Supreme Court in London address these challenges will have a tremendous impact on their respective futures.
