Judge Francisco de Jorge issued the order earlier this week for Rubiales to answer his questions at Spain’s National Court.
Rubiales kissed Spain forward Jenni Hermoso on the lips during the awards ceremony after Spain beat England to win the title on 20 August in Sydney, Australia. He said she had consented to the kiss, but Hermoso has denied that repeatedly.
Rubiales did not speak before entering the courthouse with his lawyer.
Spanish state prosecutors formally accused Rubiales last week of alleged sexual assault and an act of coercion when, according to Hermoso, he pressured her to speak out in his defence immediately after the scandal erupted.
Rubiales announced on Sunday that he was resigning from his post, from which he had already been provisionally suspended by FIFA.
De Jorge is carrying out the preliminary investigation into the accusations against Rubiales, and will then decide whether the case should go to trial.
According to a sexual consent law passed in Spain last year, Rubiales could face a fine or a prison sentence of one to four years if found guilty of sexual assault. The new law eliminated the difference between “sexual harassment” and “sexual assault,” sanctioning any non-consensual sexual act.
