¶1Plaintiff moves for summary judgment to set aside an order of the defendant, a Deputy Commissioner, Bureau of Employees’ Compensation, Department of Labor, which rejected plaintiff’s application to reopen his claim for compensation. Defendant has filed a cross-motion for summary judgment.
¶2Plaintiff was injured on March 31, 1946, while engaged as a freight handler in discharging a float in the North River at New York City. He received a temporary total and temporary partial disability award on March 29, 1951. On February 21, 1952, plaintiff made application to reopen his claim, asserting a substantial change in his condition. Thereafter the case was reopened and hearings were conducted before the defendant under the provisions of the Longshoremen’s and Harbor Workers’ Compensation Act, hereafter the Act, 33 U.S.C.A. § 922. Defendant, finding that no substantial change in plaintiff’s condition had occurred since his first award, rejected plaintiff’s application.
¶3Plaintiff contends that he was denied due process of law in that, at the hearing, the Deputy Commissioner refused to (1) allow plaintiff’s attorney, upon cross-examination, to impeach a Dr. Hyslop, one of the carrier’s medical experts, by confronting him with statements in a medical treatise tending to contradict his opinion; (2) allow plaintiff’s attorney, upon cross-examination, to question a Dr. Brock, designated as an impartial specialist, as to possible improper interest or bias.
¶4Defendant, on the other hand, urges that no rights were denied the plaintiff since common law and statutory rules of evidence and technical rules of procedure are not binding on a deputy commissioner, when he conducts hearings under the Act. Defendant further urges that since the record as a whole supports the deputy commissioner’s decision, that decision must stand.
¶5Except where certain procedural and evidentiary rules are prescribed, Section 923 of the Act makes clear that a deputy commissioner conducting a hearing “shall not be bound by common law or statutory rules of evidence or by technical or formal rules of procedure … but may make such investigation or inquiry or conduct such hearing in such manner as to best ascertain the rights of the parties.”
¶6Decision turns, therefore, not on any purported authority of the deputy commissioner to prevent or arbitrarily limit cross-examination, for he has no such áuthority, but on whether the deputy commissioner denied the substantial rights of the plaintiff by not allowing plaintiff’s attorney to proceed with the *234questions he sought to ask Doctors Hyslop and Brock. Southern Stevedoring Co., Inc. v. Voris, supra; F. H. McGraw & Co. v. Lowe, supra. The first ques-. tion, directed to Dr. Hyslop was as follows :
“Q. Do you agree, doctor, with this statement as expressed by Dr. Savitsky that ‘too frequent diagnosis of malingering is in our opinion to a large extent the expression of the underlying hostility on the part of many physicians towards patients seeking compensation ?’ ”
¶7The question was never answered for the carrier’s counsel objected.
“Mr. O’Hae: I will object to the question unless this doctor that made that statement is produced here for cross-examination.
“Mr. Sher: Well, we can’t produce Savitsky. Unfortunately, he died last week.
“The Deputy Commissioner: I will sustain the objection.”2
¶8While it is proper to confront an expert witness with a portion of a medical treatise of recognized authority and ask his opinion of the views there expressed, Travelers Ins. Co. v. Branham, D.C.1945, 61 F.Supp. 637, 638-639, no denial of due process resulted from the deputy commissioner’s ruling here. For one reason, there is no showing in the record that plaintiff established, or that Dr. Hyslop recognized, that Dr. Savitsky was an authority on the subject in dispute.
¶9The second question in issue here was directed to Dr. Brock, who coneededly did work for many insurance companies and was a consulting physician for the United States Marine Hospital and the Veterans Administration. Plaintiff’s counsel asked Dr. Brock:
“Is there one single case that you examined for an insurance company in the year 1952 where you gave causal relation?”
¶10Defendant’s objection to the question was sustained. While the deputy commissioner might have allowed plaintiff to pursue this line of questioning further in an attempt to show possible bias, it certainly cannot be said that plaintiff was denied due process of law because the deputy commissioner sustained defendant’s objection. Dr. Brock admittedly was often called as a neuro-psychiatric consultant by both insurance companies and by claimants. The deputy commissioner was well aware of this fact
¶11Finally, an examination of the record as a whole reveals substantial evidence to support the deputy commissioner’s finding that no change in plaintiff’s condition had occurred, since the original order of compensation was made. O’Leary v. Brown-Pacifie-Maxon, 1951, *235340 U.S. 504, 508, 71 S.Ct. 470, 95 L.Ed. 483. Four doctors, two for each side, testified at the hearings. Their opinions were conflicting. It is significant, however, that the one doctor who saw plaintiff both shortly after the accident in 1946, and again in 1953, testified that no significant change in plaintiff’s condition had occurred between the two examinations. This evidence, as well as the testimony of Dr. Brock, gives substantial support to the findings of the deputy commissioner.
¶12The plaintiff’s motion is denied; the defendant’s cross-motion is granted.

¶16. Examination of the testimony shows that plaintiff mentioned the names of four persons: Ncgeli and Reichert and Strauss and Savitsky (Record, pp. 125, 127). Nothing shows, however, that they were admitted authorities in the “field”. (It is not stated to which “field” plaintiff refers.)
