In this case the article in question was published by a newspaper, in fact due to legal requirement. So the law here is totally messed up. It says the data must be published, but must not be findable. A farce.
sure, I agree.
In this case I think the mistake was made by the Ministry of Labour and Social Affairs who didn't understand the consequences of publishing one person's sensitive information on the internet. In my utopia though, the newspaper would have asked (and forcefully obtained in this case thanks to the Ministry authority) permission to Mr Gonzalez to access his sensitive information, only for the amount of time required by the bidding process.
The legal requirement is for the information to be published (once) and then, in the normal course of events "forgotten" after a period of time.
It is not the publication that is a concern, it is the permanence of it, and the ease of access that the ruling deals with.
