What this dot point is asking
This WJEC AS topic asks you to explain the role and independence of the judiciary and to evaluate how effectively it protects civil liberties and checks the executive. You need to understand the Supreme Court, judicial review, the Human Rights Act, and the tension between an independent judiciary and parliamentary sovereignty.
The answer
The role and independence of the judiciary
Independence and neutrality are protected by security of tenure (senior judges cannot easily be removed by ministers), salaries paid from a protected source, appointment through the independent Judicial Appointments Commission, and the convention that politicians do not comment on active cases.
The Supreme Court
Judicial review
Judicial review is the process by which courts examine the lawfulness of decisions and actions by public bodies, including ministers. A court can rule that the executive has acted ultra vires (beyond its legal powers), unreasonably, or unfairly, and quash the decision. This is one of the main ways the judiciary checks the executive, though it reviews the legality of how power is used rather than the merits of policy.
The Human Rights Act and civil liberties
The Human Rights Act 1998 incorporated the European Convention on Human Rights into UK law. It requires public bodies to act compatibly with Convention rights and allows courts to interpret legislation in line with those rights. Where a statute cannot be reconciled with the Convention, a court may issue a declaration of incompatibility, which signals the problem to Parliament but does not strike the law down, preserving parliamentary sovereignty.
How effectively does the judiciary protect rights?
Supporters argue that judicial review and the Human Rights Act give real protection and that an independent, increasingly assertive Supreme Court has checked the government in major cases. Critics argue that the protection is limited because parliamentary sovereignty prevents courts from striking down Acts, that rights legislation can be amended or repealed, and that unelected judges lack democratic legitimacy when their decisions look political. The judiciary therefore offers strong but not unlimited protection.
Examples in context
The limit set by sovereignty. The declaration of incompatibility captures both the strength and the limit of judicial protection. When a court finds that an Act breaches Convention rights, it can publicly declare the incompatibility, putting political pressure on the government and Parliament to change the law. But it cannot annul the statute, because Parliament remains sovereign. This single device shows why the judiciary can check the executive and uphold rights, yet stops short of the power a supreme court has under a codified, entrenched constitution.

A short-answer question testing AO1 knowledge of the judiciary.
Judicial independence is protected by: security of tenure (senior judges cannot easily be dismissed by government), salaries paid from a source not subject to annual political vote, appointment through the independent Judicial Appointments Commission rather than by ministers alone, the creation of a separate Supreme Court in 2009 to divide the top court from Parliament, and the convention that politicians do not comment on cases before the courts (sub judice).
The best answers explain why each feature matters for impartial justice rather than just listing them.

An extended evaluation requiring a balanced judgement.
Case for effective protection: judicial review lets courts strike down unlawful executive action; the Human Rights Act 1998 allows courts to uphold Convention rights and issue declarations of incompatibility; an independent and increasingly assertive Supreme Court has checked the government in high-profile cases.
Case for limits: parliamentary sovereignty means courts cannot strike down an Act of Parliament, only declare it incompatible; the government can in theory amend or repeal rights legislation; judges are unelected, raising questions of legitimacy when they make political-looking decisions.
The top band weighs judicial review and the Human Rights Act against parliamentary sovereignty and democratic legitimacy, and reaches a supported judgement.
