In 1975 Don Javier abdicated as the Carlist king in favor of Carlos Hugo and according to a source, he would have expelled Sixto from Carlism for refusing to recognize the decision. It is not clear what his view on the commencing Spanish transición was; following the 1976 Montejurra events he lamented the dead, officially disowned the political views of Don Sixto and called for Carlist unity. However, in a private letter, Don Javier claimed that at Montejurra "the Carlists have confronted the revolutionaries", which has been interpreted as the followers of Don Sixto being the real Carlists according to Don Javier.
