The main secondary legal source of environmental liability in the European Union is the Directive 2004/35/CE of the European Parliament and of the Council of 21 April 2004 on environmental liability with regard to the prevention and remedying of environmental damage. Even though it was modified several times since then, it still remains the basic norm in the environmental field by establishing the regulatory frames by means of the polluter pays principle and the principle of prevention. The present study makes an overview of recent and potential further legislative steps in Hungary with regards to its implementation.
