The “causal relationship” is the direct tie between the “act” or “cause of act” and the “result”. Although the proving of this principle is consistent with public traditional rules, it is very difficult to prove it in the field of environment because
of multiple environmental damage sources.
In this research, we try to understand the difficulties and address suggested solutions to overcome them. The research is divided into two main parts: the first one defines the “causal relationship” and its proving theories, while the second part aims to present causal relationship proving difficulties in the environmental field, and suggested ways to prove it without breaking out general principles.
It became clear to us that the “produced cause theory” is one of the most appropriate methods that follows general rules, but Judge should take on his consideration the modern methods of created juristic and legislative
