A district attorney may recuse himself, whether a motion for his recusation has been filed or not, in any case in which a ground for recusation exists. A motion to recuse the district attorney shall be in writing and shall set forth the grounds therefor. The motion shall be filed in accordance with Article 521, and shall be tried in a contradictory hearing. If a ground for recusation is established the judge shall recuse the district attorney.
