Judge García-Castellón asks to locate the ERC deputy Rubén Wagensberg, currently in Switzerland. The judge has adopted this decision considering that "one of the purposes" of the investigation phase is to "ensure" the availability before the court of those allegedly responsible for the facts investigated.

Wagenberg announced that he had moved to Switzerland due to "fear" of suffering "arbitrary detention" A few months ago, the judge asked the Supreme Court to take up this case as both Wagensburg and the former Catalan president Carles Puigdemont were convicted.
