MADRID  - A Spanish court Friday delayed a corruption hearing of King Juan Carlos’ daughter Princess Cristina after prosectors lodged an appeal against her summons. Pending the result of the appeal, Judge Jose Castro agreed to postpone his summons for her to testify as a suspect on April 27 at his court in Palma on the Mediterranean island of Mallorca. “Once a decision has been given on the appeal, if its content so allows, a new date will be set,” he said. The anti-corruption prosecutor said it was basing its challenge to the summons on the principle of “equality before the law”, implying that the princess was being unfairly treated because of her royal rank.
