Final answer:
The responsibility to prove that a limitation on a charter-guaranteed freedom is reasonable rests upon the government (A). The government must show that such limits are justified and necessary for the greater societal good and that they are proportional to the aim pursued.
Step-by-step explanation:
The onus of proving that a limit on a right & freedom guaranteed by the charter is reasonable & demonstrably justified in a free & democratic society rests upon the government (A). In situations where individual rights and societal interests conflict, the balance must be carefully considered. The government has the responsibility to secure the rights and liberties of the people while ensuring the broader societal good. This involves the government justifying any limitations placed on individual freedoms, often in a court setting, demonstrating that such limitations serve a compelling societal interest and are proportionate to the objective they seek to achieve.
Constitutionalism entails a delicate balance between government authority and individual freedom, where the government must have legitimate reasons to place restrictions on individual rights. In rule-of-law countries, these rationales must be clear and convincing evidence that supports the restrictions. It is the role of judiciary systems, and particularly the Supreme Court in some jurisdictions, to ensure that any infringement upon rights and liberties is justified in the name of the common good. Therefore, it is up to the government to demonstrate that a limitation on a constitutional right is warranted, aligning with legal principles such as the necessity and proportionality of the limitation.
