Environmental rights mean the constitutional rights that is not stipulated theirs contents and scopes. Without the legal for this, it is not easy to protect environmental rights in the concrete. But in case of being infringed on them, they can be protected by a nuisance prohibition. The invasion of environmental rights can be similar to a nuisance. A nuisance implies living obstacles by smoke, gas, a liquid, the a disturbance right to enjoy sunshine, a noise, vibration and so on.
In the relief on a nuisance, an illegality is an important element. If someone violate another's environmental right, that is an illegal act in itself. This is the environmental right theory. The judgment of an illegality in general settles the theory of sufferable limit. A court has admitted them as legal rights, when environmental interests which a proprietor has possessed from old times are estimated objectively as having worth as living advantages. When the trespass for environmental interests exists and the trespass gets out of sufferable limit, a proprietor's rights are protected. An illegality is to be against the limit of sufferance.
Standards of judgment for sufferable limit are mostly the comparison of violence and the benefit and protection of the law, the public interest and a utility, the importance of damage, the existence of an assaulter's law-observance, local conditions and order relations of a land use. The problem of an illegality judgement can be easy, when environmental interests are materialized by living advantages.
