Abstract:

This paper investigates whether U.S. bankruptcy judges exhibit in-group gender bias. Using a newly assembled dataset of over 3.6 million bankruptcy filings from 2010 to 2018, I exploit the quasi-random assignment of cases to judges to estimate the effect of debtor-judge gender matching on bankruptcy outcomes. I find precisely estimated null effects: female debtors do not receive systematically different outcomes when assigned to female judges. These null effects persist across chapters, in settings where judicial discretion or gender salience may be more pronounced, and across judge characteristics. The findings suggest that, despite the importance of judicial identity in some legal settings, the structured and administrative nature of the consumer bankruptcy system may limit the role of debtor-judge gender matching in bankruptcy outcomes.

No "Sisterhood on the Bench"? New Research Finds No Evidence of Gender Matching Bias in Consumer Bankruptcy

Michelle Miller's new empirical paper, No Sisterhood on the Bench: Investigating In-Group Gender Bias in the U.S. Bankruptcy Court, asks an important question that has become increasingly prominent throughout the legal system: do judges favor litigants who share their demographic characteristics?

Using an impressive dataset of more than 3.6 million individual consumer bankruptcy cases filed between 2010 and 2018 across 61 bankruptcy courts, the paper exploits the quasi-random assignment of cases to bankruptcy judges to isolate whether female debtors fare better when their cases are assigned to female judges.

Summary

The answer, according to this study, is no.

The author finds no statistically or economically meaningful evidence that female debtors obtain better outcomes simply because their cases are assigned to female bankruptcy judges. The principal measure was whether debtors received a discharge, but the study also examined case conversion, case duration, Chapter 7 and Chapter 13 cases separately, and a variety of circumstances where judicial discretion might reasonably be expected to play a larger role. The null results remained remarkably consistent.

The paper also tested situations where one might expect gender to matter more, including Chapter 13 cases, asset cases, high-debt cases, cases with numerous creditors, secured debt, nondischargeable debt, and pro se debtors. Yet none of these settings produced evidence that female judges systematically favored female debtors.

The author further examined whether female bankruptcy trustees might exhibit similar in-group bias. While trustee assignment appeared less purely random than judicial assignment, the study still found no convincing evidence that debtor-trustee gender matching explained bankruptcy outcomes.

One interesting finding remains: female debtors were modestly more likely than similarly situated male debtors to receive a discharge. However, that difference did not appear to result from being assigned to female judges. Instead, the explanation apparently lies elsewhere.

Commentary:

This paper reinforces something many bankruptcy practitioners have experienced firsthand.

Consumer bankruptcy is unlike many other areas of litigation. Bankruptcy judges unquestionably exercise judgment and discretion, particularly in contested matters. But the overwhelming majority of consumer cases are driven by the Bankruptcy Code, Federal Rules of Bankruptcy Procedure, local rules, trustee administration, standardized forms, and objective financial information.

In many Chapter 7 cases, the judge never even sees the debtor unless a dispute develops. In Chapter 13, judges certainly play a more active role, but standing trustees perform much of the day-to-day administration of cases, with confirmation standards and statutory requirements constraining judicial discretion. Those institutional features make bankruptcy a poor environment for unconscious favoritism based simply on shared gender—a conclusion entirely consistent with this study.

That does not mean judicial identity never matters. Different judges have different approaches to statutory interpretation, procedural management, evidentiary rulings, attorney compensation, mortgage litigation, student loan issues, confirmation standards, and countless other recurring bankruptcy questions. Those differences can significantly affect litigants. But this study suggests that simply matching the gender of the judge and debtor is not one of them.

The paper also fits nicely alongside two other recent pieces of empirical bankruptcy scholarship that examine different aspects of fairness in the bankruptcy system.

First is the pending paper Racial Disparities and Bias in Consumer Bankruptcy by Sasha Indarte and her coauthors. Rather than asking whether judges favor litigants who share their demographic characteristics, that paper examines whether racial disparities emerge more broadly throughout the consumer bankruptcy system. The preliminary findings suggest that race may influence outcomes in ways that deserve careful study.

Second is Jason Iuliano's Gendered Outcomes in Student Loan Bankruptcy, 42 Emory Bankruptcy Developments Journal 43 (2026). Professor Iuliano likewise finds important differences in bankruptcy outcomes by gender, but his work asks a fundamentally different question. Rather than examining whether female judges favor female debtors, he studies whether women and men experience different success rates in student loan discharge litigation. Those are questions about substantive outcome disparities, not in-group favoritism by judges.

Taken together, these three papers highlight an important distinction.

Questions about disparate outcomes, systemic disparities, and judicial bias are not the same thing.

A finding that women achieve different outcomes than men does not necessarily mean judges are favoring one gender over another. Likewise, evidence of racial disparities would not automatically establish racial favoritism by bankruptcy judges. Differences in outcomes may arise from many sources, including financial circumstances, legal representation, creditor behavior, trustee administration, statutory requirements, or other structural features of the bankruptcy system.

Miller's paper provides persuasive evidence that bankruptcy judges, as a group, do not appear to exhibit in-group gender favoritism in consumer cases. If future research confirms meaningful racial disparities or gender-based outcome differences in other contexts, those findings need not conflict with this paper. Instead, they may point to broader institutional or structural issues that deserve attention.

That is precisely why rigorous empirical research matters. Bankruptcy policy should be guided by evidence rather than assumptions. Good scholarship not only identifies disparities—it helps us understand why they exist, which is ultimately the first step toward determining whether reforms are needed.
