A Comparative Analysis of the Precautionary Principle in Civil Liability under Modern French Law, Islamic Jurisprudence, and Iranian Law

The precautionary principle, in the context of civil law—especially when dealing with environmental issues and public health—basically means we have to take preventive measures to avoid potential harm. What this principle is really getting at is that liability doesn't only make sense after damage has already happened; rather, it has its roots in forward‑looking actions that stop harm from occurring in the first place. At the international and European levels, this idea has become well established as a turning point—shifting away from a purely compensatory logic toward a preventive one—and it's pushed national legal systems toward accepting liability even when there's scientific uncertainty.
 
Now, looking at French law: judges there, relying on a duty of caution and foresight, have taken the traditional concept of fault to a whole new stage. These days, simply failing to anticipate or properly assess a risk can itself be treated as a source of liability. That's how the precautionary principle, alongside compensation for damages, turns into a standard for careful conduct. Its goal was to protect collective interests before any injury actually occurs. In Iranian law, by drawing on jurisprudential foundations like the rules of *lā ḍarar* (no harm) and *tasbīb* (causation), it's actually possible to align this approach with the spirit of distributive justice. Why? Because in this legal system, failing to exercise foresight and caution is seen as causing harm to someone else—and that elevates civil liability from a merely compensatory institution to a preventive one. The bottom line is that civil liability, when viewed through the lens of the precautionary principle, becomes an active mechanism for safeguarding the public interest and maintaining social order. Its role shifts from mere compensation to effective prevention.
