Which legal principle allows for exceptions to the right to liberty?

The legal principle that allows for exceptions to the right to liberty is based on the notion of arrest or imprisonment under just cause. This principle is firmly rooted in legal standards worldwide, often framed within the context of ensuring public safety and order.

In order to lawfully deprive an individual of their liberty, there must be a justified reason, which typically involves the presence of a legal framework that outlines the conditions under which an arrest can be made. For example, the police must have reasonable grounds or probable cause to believe that a person has committed a crime or is about to do so, which justifies the infringement on that person's right to liberty.

This principle is essential for maintaining the balance between individual rights and the broader needs of society. It safeguards individuals from arbitrary detention and ensures there is accountability in the law enforcement process, providing a clear justification for any deprivation of liberty that occurs within the legal system. The other options relate to broader concepts that might touch upon reasons for restrictions on liberty, but they do not specifically encapsulate the principle of lawful detention based on just cause.
