Article 17.


If on the basis of the provisions of this decree a number of persons are responsible for the same soil contamination, they are jointly and severally liable.


In that case, those who have reimbursed the party suffering the damage have recourse against the other liable parties to the extent the different emissions for which they are liable have contributed to the cause of the land contamination.


The provisions of this decree are without prejudice to the possibilities of the person responsible to exercise recourse based on another legal foundation.
