The court to which the action is removed must proceed to trial and judgment therein the same in all respects as if the action had been commenced in such court. If it is necessary to have any of the original pleadings or other papers before such court, the court from which the action is removed must at any time upon the application of the district attorney or the defendant, order such papers or pleadings to be transmitted by the clerk, a certified copy thereof being retained.
