Artist Stops Oil Pipeline Cold
Alberta artist, Peter von Tiesenhausen, has effectively stopped oil corporations from putting a pipeline through his 800 acre property by covering it with artwork and copyrighting the top six inches of his land as an artwork. Realizing that mining companies can legitimately lay claim to any land underneath private property to a depth of six inches, van Tiesenhausen contacted a lawyer who drew up an intellectual property/copyright claim that said that if the oil company disturbed the top six inches in any way, it would be a copyright violation.
