The fundamental right to the protection of personal character data, as a very personal law, has to be exercised necessarily by the headline of the data, or, in the terms that he foresees the LOPD and the RLOPD, for third parties in name and representation of the person concerned. The regulations of protection of particulars do not apply to the data of deceased persons, except in the suppositions indicated in article 2.4 of the RLOPD. The request of access to determinate medical information of a dead relative does not constitute a demonstration of the law of foreseen access in the article 15 of the LOPD, but it has to be solved with regard to the applicable sectorial regulations (Law 41/2002). The medical center has to check out the fulfillment of this article, especially, the principle of proportionality.
