Which of these decisions bind the Crown Court?

The decisions of the High Court bind the Crown Court due to the hierarchical structure of the English legal system. The Crown Court is generally bound to follow the legal principles established by the High Court, as they are both part of the same hierarchy but at different levels. This means that when the High Court makes a ruling, the Crown Court must apply that ruling in similar cases, ensuring consistency and predictability in the application of the law.

In contrast, while decisions made by the County Court do establish precedents within their own jurisdiction, they do not have the authority to bind the Crown Court. Similarly, the rulings of the Court of Appeal and the Supreme Court are higher in the hierarchy than the High Court. Decisions from these courts would create binding precedents on the Crown Court, but not the other way around. Thus, the High Court's decisions hold binding authority over the Crown Court, confirming that the correct answer is indeed the decisions of the High Court.
