Takeaway
In short, this case establishes that an administrative agency may investigate, find probable cause, and later adjudicate the same matter unless additional facts show actual bias or a constitutionally intolerable risk of unfairness.
Wisconsin’s Medical Examining Board both regulated physicians and enforced state medical-practice laws. It could investigate alleged misconduct, warn or reprimand licensees, find probable cause for criminal or license-revocation proceedings, and temporarily suspend a license.
Dr. Duane Larkin, a Michigan physician licensed in Wisconsin by reciprocity, performed abortions in Milwaukee. The Board notified him that it would conduct a closed investigative hearing concerning alleged professional misconduct. Larkin and his lawyer could attend, but they could not cross-examine witnesses. After the investigation, the Board scheduled a contested hearing to determine whether Larkin had committed specified violations and whether his license should be temporarily suspended.
Larkin brought a § 1983 action seeking to stop the Board’s proceedings. A three-judge District Court restrained the contested hearing and later preliminarily enjoined the Board from using the temporary-suspension statute against Larkin. The court reasoned that due process required an independent decisionmaker: the same Board could not investigate charges and then adjudicate them. While the injunction was in place, the Board made findings of probable cause and forwarded a verified complaint to the Milwaukee County District Attorney seeking revocation and criminal proceedings.
The Supreme Court noted probable jurisdiction and reversed. It held that the mere combination of investigative and adjudicative functions within an administrative agency does not, without more, create an unconstitutional risk of bias.
Issue #1
Whether the Supreme Court had jurisdiction under 28 U.S.C. § 1253 to review the three-judge District Court’s preliminary injunction.
Holding
Yes. The Court had jurisdiction because the three-judge court had entered a preliminary injunction against enforcement of a state statute based on the asserted likelihood that Larkin’s constitutional challenge would succeed.
Reasoning
Section 1253 permits a direct appeal to the Supreme Court from an order granting or denying an interlocutory or permanent injunction in a case required to be heard by a three-judge district court. An injunction against enforcing a state statute on constitutional grounds, including a preliminary injunction resting on a high likelihood of success, falls within that provision.
Although the District Court later narrowed its order to protect only Larkin rather than declaring the statute invalid as to everyone, the case still presented a reviewable preliminary injunction against application of the state law to him.
Issue #2
Whether the District Court could declare the Wisconsin temporary-suspension statute unconstitutional and enjoin its enforcement against all licensees while granting preliminary relief.
Holding
No. A preliminary injunction should preserve the plaintiff’s interests pending final litigation, not finally declare a state statute unconstitutional or broadly bar its enforcement against nonparties.
Reasoning
Under Mayo v. Lakeland Highlands Canning Co., the question at the preliminary-injunction stage is whether serious constitutional questions are raised and whether enforcement pending a final hearing would cause irreparable injury. It is not a final determination that the challenged law is constitutional or unconstitutional.
The District Court’s original judgment therefore erred by declaring § 448.18(7) unconstitutional and enjoining the Board from using it against any licensee. Its later amended judgment removed the declaration and limited the injunction to Larkin, effectively resolving the overbreadth problem.
Issue #3
Whether deficiencies in the District Court’s findings and injunction order required vacatur and remand under Federal Rules of Civil Procedure 52(a) and 65(d).
Holding
No. Although the District Court’s original findings and order lacked sufficient specificity, a remand for fuller findings would not materially assist resolution because the controlling question was legal rather than fact-dependent.
Reasoning
Rules 52(a) and 65(d) ordinarily require adequate findings, conclusions, and reasons supporting injunctive relief. The District Court’s original opinion and judgment did not fully satisfy those requirements.
Its amended judgment did state that Larkin faced irreparable injury and had a high likelihood of success. More importantly, the District Court’s decision rested on its categorical legal premise that an agency that investigates may not adjudicate the resulting charges, not on disputed facts unique to Larkin’s case. The Supreme Court therefore decided the merits rather than ordering a costly remand for more elaborate wording.
Issue #4
Whether due process bars a state medical board from investigating alleged misconduct and then conducting an adversary hearing to decide whether to suspend the physician’s license.
Holding
No. Combining investigative and adjudicative functions in the same administrative body does not, without additional evidence of actual bias or an intolerably high risk of unfairness, violate due process.
Reasoning
Due process requires a fair tribunal and forbids decisionmakers whose financial interests, personal conflicts, or other circumstances create an unconstitutional probability of bias. But administrative adjudicators are presumed to act honestly and with integrity, and a party challenging their impartiality must overcome that presumption with more than the fact that they previously investigated the matter.
The Court’s precedents rejected the proposition that prior institutional investigation or expression of a preliminary view automatically disqualifies an agency from adjudicating. In FTC v. Cement Institute, the Federal Trade Commission could adjudicate matters it had previously investigated and on which it had expressed views. Likewise, a hearing examiner was not disqualified merely because earlier rulings against a party were reversed, and the Court had sustained administrative systems in which an official both developed facts and made an initial disability decision.
Congress itself had adopted no universal separation-of-functions rule. The federal Administrative Procedure Act generally separates investigative or prosecutorial staff from adjudicatory employees, but expressly exempts the agency itself and its members. That legislative choice reflected the practical variety of administrative structures and reinforced the conclusion that combining functions is not inherently unconstitutional.
In re Murchison did not control. There, a judge acting as a one-man grand jury personally accused witnesses of contempt and then tried them while relying on untestable personal impressions from secret proceedings. The Wisconsin Board, by contrast, did not become a personal adversary of Larkin, and nothing in the record showed that its members had irrevocably prejudged the evidence.
The Board’s exposure to evidence during a nonadversary investigation was insufficient by itself to establish bias at a later contested hearing. Larkin’s counsel attended the investigative sessions, knew the evidence presented, and Larkin was offered an opportunity to explain that evidence. The record contained no specific basis to conclude that the Board could not fairly decide the case on the evidence developed in the adversary proceeding.
Issue #5
Whether the Board’s post-investigation findings of probable cause and referral of revocation and criminal matters to the district attorney made the Board constitutionally unable to adjudicate a later suspension proceeding.
Holding
No. A preliminary probable-cause determination and the ultimate adjudication serve different purposes; their combination in the same agency does not itself establish unconstitutional prejudgment.
Reasoning
Judges routinely decide whether probable cause exists for an arrest warrant or whether evidence warrants holding a defendant for trial, yet those preliminary decisions do not ordinarily disqualify them from presiding at trial. Similarly, agencies commonly receive investigative results, approve charges, and later take part in adjudication.
A finding of probable cause is not a finding of ultimate liability. The Board could conclude after a full adversary hearing that Larkin’s license should not be suspended without contradicting its earlier conclusion that the available preliminary evidence justified further proceedings.
The Court left open the possibility that special facts in another case could show an intolerably high risk of unfairness—for example, if an agency’s prior view effectively foreclosed genuine consideration of the later evidence. But Larkin had not made that showing here, so the District Court abused its discretion by issuing the preliminary injunction.
