A creator can only prevent a performer from using a work that has not yet been disseminated, in other words prior to its premiere performance. The moral right held by creators with respect to their own works empowers them to decide whether their work should be disseminated and in what way.
In general terms, once the work has been disseminated, the creator cannot prohibit any performer from using the work. Nonetheless, the author may exceptionally notify the Management Entity (in this case, the SGAE) that the use of a particular work is prohibited by a specific performer. In this way, whenever the Society licenses that specific item from the repertoire, it will have to state on the licence the condition imposed by the creator.
