Which of the following statements is untrue?

The statement that decisions of the Supreme Court override statute is untrue because, in the hierarchy of the legal system, statutes enacted by Parliament take precedence over common law, including judicial decisions made by the Supreme Court. While the Supreme Court can interpret statutes and set important precedents, its decisions cannot nullify or override the statutes directly; this is a fundamental principle of parliamentary sovereignty.

In contrast, the other statements reflect accurate principles of legal operation in the context of the Supreme Court. Appeals from the Supreme Court may have limited routes for further appeal, but under specific circumstances, if there are questions of EU law, matters can be referred to the European Court of Justice. Furthermore, the Supreme Court has the flexibility to depart from its own previous decisions when it sees fit, which distinguishes it from lower courts that must adhere to established precedents. Lastly, decisions made by the Supreme Court indeed bind all lower courts, establishing a uniform application of law throughout the judicial system. This interaction between statutes, judicial decisions, and the hierarchy of courts is crucial for understanding the functioning of the legal framework.
