What principle must not be violated to ensure an arrest is considered valid?

To ensure that an arrest is considered valid, it is essential to adhere to the principle of fundamental justice. This principle is rooted in legal doctrines that safeguard an individual's rights and freedoms, ensuring that the law is applied fairly and equitably. Fundamental justice encompasses various aspects, including the right to be informed of the reasons for arrest, the right to legal counsel, and the right to a fair trial.

In practice, this means that an arrest must not take place without reasonable grounds and must adhere to due process. If an arrest violates fundamental justice, it could be deemed unlawful, resulting in the potential for charges to be dismissed or evidence obtained during the arrest being excluded in court.

While public interest, authority of the officer, and documentation of the event are important considerations in the context of law enforcement, they do not carry the same foundational weight as the principle of fundamental justice. An arrest might be conducted with a relevant public interest or proper authority, but if it violates fundamental justice, it jeopardizes the validity of the entire process.
