In tort law, liability is primarily based on the infringement of a legal right, regardless of actual damage.
- A person can be held liable even if no physical damage occurred, as long as a legal right is violated (known as actionable per se).
- Option A is incorrect because quantum of damage is relevant for compensation, not establishing liability.
- Option B is incorrect because intention is not always required (e.g., negligence).
- Option D (public interest) is relevant in constitutional law or PIL, not torts.
