The Inquisition was an ecclesiastical court. It had no jurisdiction over Jews.
"With energy and connections, it was inevitable that Torquemada should rise to power. After studying theology at the Dominican convent of San Pablo in Valladolid, he became prior of Santa Cruz convent in Segovia. He also became confessor to the royal court.
There he whispered in the ears of King Ferdinand and Queen Isabella that many Jewish converts were secretly practicing Judaic rites while outwardly pretending to be Christians."
The Catholic church claims to have jurisdiction over everyone whether they like it or not.
