Heading II.
Third party at fault and mandatory government order


Article 15.5.3. An operator is not obliged to bear the costs of measures taken by virtue of this title, if he is able to demonstrate that the environmental damage or the immediate threat that such damage will occur was caused by a third party, despite the fact that appropriate safety measures were taken and insofar as the third party involved is not a legal predecessor, representative, appointee or agent of the operator.

Article 15.5.4. An operator is not obliged to bear the costs of measures taken by virtue of this title, if he is able to demonstrate that the environmental damage, or the immediate threat that such damage will occur, results from the following of a enforcement order or instruction issued by a government authority, unless it is an order or instruction resulting from an emission or incident caused by the activities of the operator himself.
