All questions of law arising upon the pleadings or in any other way arising from the cause, subsequent to the filing of the declaration of taking and the deposit of the fund, and subsequent to the filing of a notice of appeal, if any, shall be passed on by the presiding judge who may, from time to time, make such orders and give such directions as are necessary to speed the cause, and as may be consistent with justice and due process of law; but no jury trial shall be had except in open court.
