What is the implication of laws that lack clear definitions according to principles of fundamental justice?

Laws that lack clear definitions can lead to arbitrary enforcement, which is a significant concern in the context of fundamental justice. The principles of fundamental justice, as guaranteed under Section 7 of the Canadian Charter of Rights and Freedoms, ensure that individuals are treated fairly, that laws are clear, and that individuals are not subject to unpredictable or irrational application of the law.

When laws are vague or ambiguous, it can result in law enforcement and judicial interpretations that lack consistency. This unpredictability can mean that individuals facing similar situations may be treated differently based on how a law is applied. Such arbitrariness undermines the rule of law and can violate an individual's rights by failing to provide a clear standard for behavior, thus infringing on the principles of fairness and justice.

This understanding highlights the importance of precision and clarity in legal texts, as it allows individuals to understand their rights and obligations, and prevents the abuse of power by authorities who may apply vague laws in a discriminatory or unjust manner.
