It is contended by the plaintiff in error that the full board did not fulfill its legal function in this case of conducting a de novo1 investigation, but undertook to sit only as an appellate body. Where it appears from the award entered that the board acts upon the case only in an appellate capacity without deciding anew the issues raised, such action is illegal and the award must be. reversed.

296 (
In two instances during the hearing, once in ruling over the objection of counsel for the. employer that certain testimony was admissible, and again in refusing, over objection, to admit documentary evidence, the deputy director hearing the case stated in connection with his ruling: “I’m not bound by the rules of evidence and with the discretion given to the deputy director, I’m not admitting it.” It is contended that the rulings were erroneous, prejudicial to the employer’s case, and constitute reversible error.
Neither this court nor the Supreme Court has ever made a statement which can reasonably be construed to grant immunity from the rules of legal procedure to the Board of Workmen’s Compensation, sitting either as a body or individually, nor has the legislature in creating the. law which these courts interpret ever intimated that hearings may be conducted outside the fundamental framework of the law. The provision for appeal to the courts is of itself sufficient indication of this fact. “The State Board of Workmen’s Compensation is an administrative commission, with such jurisdiction, powers, and authority as may be conferred upon it by the General Assembly.”

It is true that an aggrieved party cannot assign error, as he can in a case tried before a court, on the illegal admission or ex-

elusion of evidence, and it may be this that the director had in mind in stating he was not bound by the rules of evidence. It will form a basis for review, however, that the board acted in excess of its powers, and an arbitrary and material disregard of those fundamental legal rules under which issues must be decided would be in excess of the powers of the board acting in a quasi-judicial capacity, and would also be a decision under an erroneous legal theory.

However, the appeal here is not from the decision of the deputy director but from the decision of the full board. The hearing before the full board is

the parties may offer additional evidence, and the board has a discretion in hearing additional testimony. Code § 114-707;

296, supra. Had the plaintiff in error desired to' insist upon the admissibility and materiality of the documentary evidence rejected at the first hearing it could and should have offered the same upon the appeal, but it did not do so. While under Code § 114-707 the full board has a discretion as to whether or not it shall hear new evidence or review only the evidence before the deputy director, that discretion does not extend to cases where evidence was
properly offered
in the first instance and erroneously rejected, and is re-offered when the case is under consideration by the full board. Upon a review by the full board of all the evidence which was before the single director, it is the duty of that body to consider all evidence properly before the single director, even though erroneously excluded and not considered by him. The evidence was not before the board, and it is not included in the record here. Whether or not error existed in its exclusion is impossible to say, but the error, if any, was not committed by the full board, from the decision of which this appeal is taken. Nor will it be presumed that the full board gave weight to testimony objected to as hearsay (assuming but not deciding that the testimony was ini fact subject to the objection), for which reason the admission of hearsay

testimony would not be a ground for reversal.
