Law of Civil Procedure

If there is ground for the judge to be disqualified and he fails to recuse himself, a litigant may request his disqualification. If the ground for disqualification is not stated in Article 96 of this Law, a motion for disqualification shall be filed before any defense or plea is presented in the case; otherwise such right is forfeited. Nevertheless, such motion may be filed if the grounds therefor occurred afterwards or if the petitioner proves that he had no knowledge thereof. In any case, no motion for disqualification may be granted after closing of arguments.
