When Law Is Silent: How to Compensate for the Harm to the Health or Property in the Absence of a Particular Harm-Doer?

Abstract Legal rules aimed at compensation for the harm caused by a particular state, individual, or legal entity (for example, oil pollution of the sea due to a tanker accident) are well studied and constantly used in scientific literature and international law practice. Meanwhile, every year, the number of cases of harm when the particular guilty party cannot be established grows; this is why it is almost impossible to compensate for the harm caused. Such cases include collisions of satellites causing space debris; the consequences of climate change for agriculture, forestry, and the health of citizens; and the pollution of the World Ocean with plastic debris, ballast water, and abandoned nets. There are more such cases at the national level. After studying acts of international environmental law, national legislation, and several examples from judicial practice, we show that compensation for the harm caused to life, health, or property in the absence of a particular harm-doer is difficult or impossible to prove. This is why actions that can prevent subjectless environmental harm are taken at the national level in certain countries by developing measures to mitigate and adapt to climate change, licensing space activities, and taking preventive measures against the formation of plastic debris and its pollution of the seas, etc. This trend should be continued, and the experience gained by certain states should be used in developing new acts of international environmental law. This will ensure the next step towards preventing environmental harm where it is impossible to establish the doer’s name.
