Any legislation in a field which is governed by the Agreement shall be dealt with according to the procedures laid down in the Agreement and the Contracting Parties shall endeavour to elaborate corresponding EEA rules.
In all other cases the Contracting Parties shall inform the EEA Joint Committee of the measures and, whenever necessary, endeavour to adopt provisions to ensure that the measures are not circumvented through the territory of the other Contracting Parties.
If no agreement can be reached on such rules or provisions, the Contracting Party concerned may take measures necessary to prevent circumvention.
