11.1.1. Despite any provision to the contrary in any Act, the expropriation indemnity for property to which section 11 or 11.1 applies is fixed on the basis of the value of the property and of the damage directly caused by the expropriation on the date of the expropriation, but without taking into account the increased value attributable to the public announcement, made by the Government or the authority responsible for carrying out a shared transportation infrastructure project, of the planned route for the shared transportation system or the planned site of its stations.
