  Mr. Justice Jackson
  delivered the opinion of the Court.
  One Cunningham applied to the Interstate Commerce Commission for a certificate of public convenience and necessity to authorize extension of his existing motor carrier route. A railroad and eleven motor carriers, including appellee, intervened to oppose. The issues were referred to an examiner who after hearing recommended that, with exceptions not material here, a certificate be granted. Appellee excepted, whereupon Division 5 of the Commission, in substance, approved the recommendation. Appellee requested reconsideration by the full Commission, which was denied, and then petitioned for “extraordinary relief,” which also was refused. The Commission thereupon issued a certificate to Cunningham. Appellee, upon the ground that .the evidence did not show need for the additional transportation service, petitioned the District Court to set aside the certificate and order. The Commission and the United States answered and a three-judge court was convened.
  On the day appointed for hearing, appellee moved for leave to amend its petition to raise, for the first time, a contention that the Commission’s action was invalid for want of jurisdiction because the examiner had not been appointed pursuant to § 11 of the Administrative Procedure Act. The District Court allowed amendment and, upon proof that the appointment had not been in accordance with that Act, invalidated the order and certificate without going into the merits of the issue tendered in the original complaint. This appeal by the United States and the Interstate Commerce Commission raises but a single question — whether such an objection, first made at that stage of the proceedings, was not erroneously entertained. We hold that it was.
  Appellee did not offer nor did the court require any excuse for its failure to raise the objection upon at least one of its many opportunities during the administrative proceeding. Appellee does not claim to have been misled or in any way hampered in ascertaining the facts about the examiner’s appointment. It did not bestir itself to learn the facts until long after the administrative proceeding was closed and months after the case was at issue in the District Court, at which time the Commission promptly supplied the facts upon which the contention was based and sustained.
  The apparent reason for complacency was that it was not actually prejudiced by the conduct or manner of appointment of the examiner. There is no suggestion that he exhibited bias, favoritism or unfairness. Nor is there ground for assuming it from the relationships in the proceeding. He did not act and was not expected to act both as prosecutor and judge. The Commission, which appointed him, did not institute or become a party in interest to the proceeding. Neither it nor its examiner had any function except to decide justly between contestants in an adversary proceeding. The issue is clearly an afterthought, brought forward at the last possible moment to undo the administrative proceedings without consideration of the merits and can prevail only from technical compulsion irrespective of considerations of practical justice.
  In Riss & Co. v. United States, 341 U. S. 907, this Court held that officers hearing applications for certificates of convenience and necessity under § 207 (a) of the Interstate Commerce Act are subject to the provisions of the Administrative Procedure Act. But timeliness of the objection was not before us, because in that case the examiner’s appointment had been twice challenged in the administrative proceedings, once, as it should have been, before the examiner at the hearings and again before the Commission on a petition for rehearing. That decision established only that a litigant in such a case as this who does make such demand at the time of hearing is entitled to an examiner chosen as the Act prescribes.
  We have recognized in more than a few decisions, and Congress has recognized in more than a few statutes, that orderly procedure and good administration require that objections to the proceedings of an administrative agency be made while it has opportunity for correction in order to raise issues reviewable by the courts. It is urged in this case that the Commission had a predetermined policy on this subject which would have required it to overrule the objection if made. While this may well be true, the Commission is obliged to deal with a large number of like cases. Repetition of the objection in them might lead to a change of policy, or, if it did not, the Commission would at least be put on notice of the accumulating risk of wholesale reversals being incurred by its persistence. Simple fairness to those who are engaged in the tasks of administration, and to litigants, requires as a general rule that courts should not topple over administrative decisions unless the administrative body not only has erred but has erred against objection made at the time appropriate under its practice.
  It is argued, however, that this case falls outside of this general rule and the result below is technically compelled because, if the appointment of the hearing examiner was irregular, the Commission in some manner lost jurisdiction and its order is totally void. This inference is drawn from our decision in Wong Yang Sung v. McGrath, 339 U. S. 33, for it is contended we could not have sustained a collateral attack by writ of habeas corpus in that case unless we found the defect in that examiner’s appointment to be one of jurisdictional magnitude. We need not inquire what should have been the result upon that case had the Government denied or the Court considered whether the objection there sustained was taken in time. The effect of the omission was not there raised in briefs or argument nor discussed in the opinion of the Court. Therefore, the case is not a binding precedent on this point. Even as to our own judicial power or jurisdiction, this Court has followed the lead of Mr. Chief Justice Marshall who held that this Court is not bound by a prior exercise of jurisdiction in a case where it was not questioned and it was passed sub silentio.
  The question not being foreclosed by precedent, we hold that the defect in the examiner’s appointment was an irregularity which would invalidate a resulting order if the Commission had overruled an appropriate objection made during the hearings. But it is not one which deprives the Commission of power or jurisdiction, so that even in the absence of timely objection its order should be set aside as a nullity.
  The judgment is reversed and the cause remanded to the District Court for determination on the merits.
  Reversed.

  100 F. Supp. 432.
  Our decision in the Riss case was announced after the administrative proceeding herein, but before the District Court’s hearing. Riss apparently prompted appellee to raise the point about the examiner’s qualifications in the District Court.

  Section 9 (a) of the Securities Act of 1933, 15 U. S. C. §77i; §25 (a) of the Securities Exchange Act of 1934, 15 U. S. C. § 78y; § 24 of the Public Utility Plolding Company Act, 15 U. S. C. § 79x; § 10 of the Pair Labor Standards Act, 29 U. S. C. §210; § 10 (e) of the National Labor Relations Act, 29 U. S. C. § 160 (e).
  The Government informs us that in about five thousand cases commenced after the effective date of the Administrative Procedure Act, orders are for an indefinite period vulnerable to attack if no timely objection during the administrative process is required. The policy of the Commission is to grant application for rehearing in cases where applicant made the objection before the examiner. Since its established practice is not to consider issues not raised before the examiner, it will refuse rehearings in other cases.
