Water Pollution Control Act Article 66-2

For those benefited from violating this Act, fine may be increased to the extent appropriate within the scope of the benefit gained.A person who, having made another person liable for penalty in consequence of an act in breach of duty under administrative law committed by him for the benefit of such person, has nevertheless received no penalty himself despite the fact that he has gained benefits in property as a result of such act, may be demanded to have such benefits in property returned to a certain extent within the scope of the value of the benefits which he has gained.If a person is liable for penalty by reason of his commission of an act in breach of duty under administrative law, but another person who, despite the fact that he has gained benefits in property as a result of such act, has received no penalty therefor, the latter may be demanded to have such benefits in property returned to a certain extent within the scope of the value of the benefits which he has gained.The demand for returning of benefits under the three preceding paragraphs shall be made in the form of an administrative disposition to be delivered by the competent agency imposing the sanction; the benefit mentioned before must include conspicuous benefits and inconspicuous benefits; inconspicuous benefits are the costs that should have been made but were avoided. The central competent authority shall determine the method to calculate the amount of returning benefit.
