What is a key factor that must justify a limitation on a right?

A key factor that must justify a limitation on a right is the consideration of public interest and societal importance. This principle is rooted in international human rights law, which recognizes that rights are not absolute and may be subject to restrictions that are necessary to achieve significant societal goals.

Public interest serves as a crucial foundation for imposing limitations, as it balances individual rights against the welfare, safety, or health of the community at large. This means that limitations are most justifiable when they are aimed at protecting fundamental public interests such as national security, public safety, or the rights and freedoms of others.

For a limitation to be legitimate, it must be proportionate and necessary, addressing a pressing social need rather than merely serving arbitrary or discriminatory purposes. Thus, any restriction on a right must be carefully scrutinized to ensure it aligns with notable public benefits and does not infringe upon rights more than necessary.
