A change of venue may be allowed upon motion:
(1) Where there is reason to believe that an impartial trial cannot be had in the district or municipal court in which the action was commenced; or
(2) Where the convenience of witnesses or the ends of justice would be forwarded by the change.
When such change is ordered, it shall be to the district court of another district in the same county, if any, otherwise to the district court of an adjacent district in another county: PROVIDED, That where an affidavit of prejudice is filed against a judge of a municipal court the cause shall be transferred to another department of the municipal court, if one exists, otherwise to a judge pro tempore appointed in the manner prescribed by law. The court to which a case is removed on change of venue under this section shall have the same jurisdiction, either civil or criminal to hear and determine the case as the court from which the case was removed.
