In February 2003 the French NCP received a request for review from a trade union alleging that a Swiss multinational enterprise had breached the environment, disclosure, and employment and industrial relations provisions of the Guidelines with its mining activities in France.

The NCP offered its goods offices to the parties and co-ordinated with the Swiss NCP during the process. The examination of the specific instance took some time due to long-standing parallel judicial proceedings. The NCP concluded the specific instance in 2008, reminding the multinational enterprise of the French and European legislations relating to rehabilitation of polluted soil.
