Review Questions

• How does the principle of legality interact with the rule of law in protecting individual rights?
  • The principle of legality is a key aspect of the rule of law as it ensures that individuals are only held accountable under laws that are clear and publicly available. This interaction protects individual rights by preventing arbitrary actions by the state. If laws are vague or retroactively applied, it undermines citizens' ability to understand their obligations and limits their freedoms.
• Discuss the implications of parliamentary sovereignty on the principle of legality regarding retrospective legislation.
  • Parliamentary sovereignty allows Parliament to make or unmake any law; however, this can conflict with the principle of legality if Parliament attempts to pass retrospective legislation. Such actions may violate the fundamental notion that individuals should not be punished for actions that were not illegal at the time they were committed. This highlights a tension between legislative authority and individual rights under the principle of legality.
• Evaluate how judicial interpretation upholds the principle of legality within the framework of human rights protections.
  • Judicial interpretation plays a crucial role in upholding the principle of legality by ensuring that laws align with human rights standards. Courts often scrutinize legislation to confirm that it provides adequate protection against arbitrary state actions. This evaluation not only reinforces the rule of law but also emphasizes that any limitations on individual rights must be clearly stated in law, thus fostering a legal environment where citizens can trust in their protections against unjust governance.
