We have just received notice of an encouraging report in the on-line version of the French News which describes measures proposed by maires in the Var Departement to obstruct the upcoming presidential elections in their region in the event of candidates being unwilling to give assurances regarding shale gas exploration/exploitation. Here is the link to the report by journalist Ken Pottinger
You will see from our last report that other measures are progressively being introduced including local laws or arrêtés banning the use of roads and water for instance. Numerous communes in the Lot including the Grand Cahors administration have taken such powers.
You may wish to ask your maire if anything similar is planned.
