Title IX processes generally use the “preponderance of the evidence” or “clear and convincing” standard, not “beyond reasonable doubt”. Is a lower standard justified when the sanction is expulsion rather than prison?
Every system that makes decisions under uncertainty must decide how sure it needs to be. Criminal courts require proof beyond reasonable doubt. Civil courts usually require a preponderance of the evidence, meaning that the claim is more likely true than not. Between them sits “clear and convincing evidence”, used in some civil matters where the stakes are high. American university disciplinary processes under Title IX have swung between these lower standards as federal guidance has changed: the 2011 guidance required preponderance; the 2020 rules allowed either preponderance or clear and convincing; and the 2024 rules, since vacated, favoured preponderance. The question is whether anything lower than the criminal standard is justified when a student’s future is at stake.
What standards of proof do
A standard of proof is a way of distributing the risk of error. Any decision procedure will sometimes get things wrong. It may find someone responsible who did nothing wrong (a false positive), or clear someone who did (a false negative). A higher standard reduces false positives at the cost of more false negatives. A lower standard does the reverse.
The criminal standard reflects a judgement, often summarised in Blackstone’s remark that it is better that ten guilty persons escape than that one innocent suffer, that false positives in criminal cases are much worse than false negatives. Convicting an innocent person of a serious crime takes their liberty and marks them permanently. The cost of wrongly acquitting is real but, on this view, lower.
Preponderance reflects a judgement that the two errors are roughly equally bad. It is used in civil disputes where, for example, money must go to one party or the other, and there is no reason to favour either.
The case for a lower standard on campus
Supporters of preponderance in campus cases make three main arguments.
First, the sanction is different in kind. Expulsion is serious, but it does not take away liberty or create a criminal record. The respondent can continue his education elsewhere. Since the cost of a false positive is lower than in criminal cases, the standard can reasonably be lower.
Second, the costs of false negatives are high and fall on an identifiable person. If a university wrongly clears someone, the complainant may have to continue living, studying and socialising alongside the person she reported. A high standard makes this more likely.
Third, equality between parties. Under Title IX, both complainant and respondent are students whose education the university must protect. Preponderance treats their interests as equal; a higher standard tips the balance towards the respondent.
The case against
Critics, including many legal scholars, respond on several fronts.
First, the consequences of a finding are more severe than supporters admit. A student expelled for sexual assault may find it difficult to transfer, may lose professional opportunities, and carries a stigma that may follow them for years. These are not criminal penalties, but they are close.
Second, campus processes often lack the other protections that make civil preponderance tolerable: full discovery, professional advocates, rules of evidence and appeal to an independent court. A low standard combined with weak procedures greatly increases the risk of error.
Third, sexual assault cases frequently turn on credibility contests with little corroboration. Under preponderance, a fact-finder who slightly prefers one account can find responsibility. Given the stakes, critics argue that slight preference is not enough.
A middle position
Many have suggested that clear and convincing evidence is the right compromise: higher than preponderance, reflecting the seriousness of the stakes, but lower than the criminal standard, reflecting the difference between expulsion and prison. The 2020 regulations allowed institutions to choose it.
Another approach is to vary the standard with the sanction. A finding that leads to a no-contact order or a warning might use preponderance. A finding that leads to expulsion might require clear and convincing evidence. This tracks the principle that the more serious the consequence, the more certain the decision-maker should be.
In the case behind these seminars
Cornell’s hearing found several respondents responsible and imposed sanctions including expulsions, while the district attorney declined to charge. The difference in standard of proof is one explanation for the difference in outcome. That is not, in itself, evidence that either decision was wrong. Two systems with different standards and different purposes can legitimately reach different conclusions on the same facts. But it does mean that public discussion should be careful: a campus finding is not a criminal conviction, and a decision not to charge is not an acquittal.
For discussion
If you were facing expulsion, what standard would you want? If you had reported an assault, what standard would you want? Is there a standard you would accept from both positions?
