The members of the Boards of Directors of the municipal companies can access determinate particulars of the workers of these companies only in so far as this access is necessary for the achievement of the functions that they have assigned as members of the organ of direction. The particulars of the workers in which they have access have to be suitable, pertinent and non excessive, depending on the legitimate purpose that is alleged in each case and will not be able to be treated for other different purposes in which they justified its access.
