Which amendment prevents a judge from deciding a case

All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.

The Due Process Clause requires that the decision to deprive a person of a protected interest be entrusted to an impartial decision maker. This rule applies to both criminal and civil cases.1 Footnote
Tumey v. Ohio, 273 U.S. 510 (1927) ; In re Murchison, 349 U.S. 133 (1955) ; Goldberg v. Kelly, 397 U.S. 254, 271 (1970) . See also Amdt14.S1.5.5.2 Impartial Judge and Jury. The Supreme Court has explained that the “neutrality requirement helps to guarantee that life, liberty, or property will not be taken on the basis of an erroneous or distorted conception of the facts or the law” and “preserves both the appearance and reality of fairness . . . by ensuring that no person will be deprived of his interests in the absence of a proceeding in which he may present his case with assurance that the arbiter is not predisposed to find against him.” 2 Footnote
Marshall v. Jerrico, 446 U.S. 238, 242 (1980) ; Schweiker v. McClure, 456 U.S. 188, 195 (1982) . Thus, a showing of bias or of strong implications of bias was deemed made where a state optometry board, made up of only private practitioners, was proceeding against other licensed optometrists for unprofessional conduct because they were employed by corporations. Since success in the board’s effort would redound to the personal benefit of private practitioners, the Court thought the interest of the board members to be sufficient to disqualify them. Gibson v. Berryhill, 411 U.S. 564 (1973) . Similarly, the Court has held that the conduct of deportation hearings by a person who, while he had not investigated the case, was also an investigator who must judge the results of others’ investigations just as one of them would some day judge his, raised a substantial problem. The Court resolved the issue through statutory construction. Wong Yang Sung v. McGrath, 339 U.S. 33 (1950) .

There is a “presumption of honesty and integrity in those serving as adjudicators,” so the burden is on an objecting party to show a conflict of interest or some other reason for disqualification of a specific officer or for disapproval of an adjudicatory system as a whole. The Court has held that combining functions within an agency, such as by allowing members of a State Medical Examining Board to both investigate and adjudicate a physician’s suspension, may raise substantial concerns, but does not by itself establish a violation of due process.3 Footnote
Withrow v. Larkin, 421 U.S. 35 (1975) . Where an administrative officer is acting in a prosecutorial, rather than judicial or quasi-judicial role, a lower standard of impartiality applies. Marshall v. Jerrico, 446 U.S. 238, 248–50 (1980) (regional administrator assessing fines for child labor violations, with penalties going into fund to reimburse cost of system of enforcing child labor laws). But “traditions of prosecutorial discretion do not immunize from judicial scrutiny cases in which enforcement decisions of an administrator were motivated by improper factors or were otherwise contrary to law.” Id. at 249. The Court has also held that the official or personal stake that school board members had in a decision to fire teachers who had engaged in a strike against the school system in violation of state law was not sufficient to disqualify them.4 Footnote

Sometimes, to ensure an impartial tribunal, the Due Process Clause requires a judge to recuse himself from a case. In the 2009 case Caperton v. A. T. Massey Coal Co. , the Court noted that “most matters relating to judicial disqualification [do] not rise to a constitutional level,” and that “matters of kinship, personal bias, state policy, [and] remoteness of interest, would seem generally to be matters merely of legislative discretion.” 5 Footnote
556 U.S. 868, 876 (2009) (citations omitted). The Court added, however, that “the Due Process Clause incorporated the common-law rule that a judge must recuse himself when he has ‘a direct, personal, substantial, pecuniary interest’ in a case.” 6 Footnote
Id. (quoting Tumey v. Ohio, 273 U.S. 510, 523 (1927) ). In addition, although “[p]ersonal bias or prejudice ‘alone would not be sufficient basis for imposing a constitutional requirement under the Due Process Clause,’” there are “circumstances ‘in which experience teaches that the probability of actual bias on the part of the judge or decision maker is too high to be constitutionally tolerable.’” 7 Footnote
Id. Those circumstances include “where a judge had a financial interest in the outcome of a case” or “a conflict arising from his participation in an earlier proceeding.” 8 Footnote
Id. at 877 .

In judicial recusal cases, the Court has explained, “[t]he inquiry is an objective one. The Court asks not whether the judge is actually, subjectively biased, but whether the average judge in his position is ‘likely’ to be neutral, or whether there is an unconstitutional ‘potential for bias.’” 9 Footnote
Id. at 881 . In Caperton , a company appealed a jury verdict of $50 million, and its chairman spent $3 million to elect a justice to the Supreme Court of Appeals of West Virginia at a time when “[i]t was reasonably foreseeable . . . that the pending case would be before the newly elected justice.” 10 Footnote
Id. at 886 . The justice was elected, declined to recuse himself, and joined a 3-2 decision overturning the jury verdict. The Supreme Court, in a 5-4 opinion written by Justice Anthony Kennedy, concluded that there was “a serious risk of actual bias—based on objective and reasonable perceptions—when a person with a personal stake in a particular case had a significant and disproportionate influence in placing the judge on the case by raising funds or directing the judge’s election campaign when the case was pending or imminent.” 11 Footnote
Id. at 884 .

Subsequently, in the 2016 case Williams v. Pennsylvania , the Court found that the right of due process was violated when a judge on the Pennsylvania Supreme Court who participated in a case denying post-conviction relief to a prisoner convicted of first-degree murder and sentenced to death had, in his former role as a district attorney, given approval to seek the death penalty in the prisoner’s case.12 Footnote
136 S. Ct. 1899, 1903 (2016) . Relying on Caperton , which the Court viewed as having set forth an “objective standard” that requires recusal when the likelihood of bias on the part of the judge is “too high to be constitutionally tolerable,” 13 Footnote
Id. (internal quotations omitted). the Williams Court held that there is an impermissible risk of actual bias when a judge had previously had a “significant, personal involvement as a prosecutor in a critical decision regarding the defendant’s case.” 14 Footnote
Id. at 1905 . The Court based its holding, in part, on earlier cases that had found impermissible bias occurs when the same person serves as both “accuser” and “adjudicator” in a case.15 Footnote
Id. at 1905 (citing In re Murchison, 349 U.S. 133, 136–37 (1955) ). The Court also noted that “[n]o attorney is more integral to the accusatory process than a prosecutor who participates in a major adversary decision.” Id. at 1906 . It reasoned that authorizing another person to seek the death penalty represents “significant personal involvement” in a case,16 Footnote
Id. at 1907 . See also id. at 1907–08 (noting that the judge in this case had highlighted the number of capital cases in which he participated when campaigning for judicial office). and took the view that the involvement of multiple actors in a case over many years “only heightens” —rather than mitigates—the “need for objective rules preventing the operation of bias that otherwise might be obscured.” 17 Footnote
Id. at 1907 . As a remedy, the Court remanded the case for reevaluation by the reconstituted Pennsylvania Supreme Court. Notwithstanding the fact that the judge in question did not cast the deciding vote, the Williams Court viewed the judge’s participation in the multi-member panel’s deliberations as sufficient to taint the public legitimacy of the underlying proceedings and constitute reversible error.18 Footnote
Id. at 1909–10 . Likewise, the Court rejected the argument that remanding the case would not cure the underlying due process violation because the disqualified judge’s views might still influence his former colleagues, as an “inability to guarantee complete relief for a constitutional violation . . . does not justify withholding a remedy altogether.” Id. at 1910 .
