Rippo v. Baker
The Supreme Court threw out the Nevada Supreme Court's rejection of a death-row inmate's judicial-bias claim, ruling that Nevada's courts had demanded proof of actual bias when the Constitution only requires showing an unacceptably high risk of bias.
The case now goes back to Nevada's courts, which must reconsider the inmate's claim that his trial judge -- who was secretly under federal investigation with help from the same prosecutor's office trying him -- should have been disqualified, this time using the correct constitutional standard.
How it got here: A trial judge and, later, a different judge denied Rippo's recusal and new-trial motions; the Nevada Supreme Court twice affirmed, and Rippo sought Supreme Court review.
The Case in Depth
What happened
Michael Damon Rippo was convicted of first-degree murder in Nevada and sentenced to death. During his trial he learned his judge was the target of a federal bribery investigation and suspected the local district attorney's office -- the same office prosecuting him -- was helping with that probe. He asked the judge to step aside, arguing a judge cannot fairly decide a case brought by people who are simultaneously investigating him.
The question before the Court
Did Nevada's courts use the right legal test when they rejected a death-row inmate's claim that his trial judge should have stepped aside?
Why it matters
Death-row and other defendants who argue a judge was too compromised to rule fairly gain a clearer, more protective legal test: they don't have to prove the judge was actually biased, only that the situation created too great a risk of bias. Courts nationwide reviewing judicial-disqualification claims must apply this looser, more defendant-friendly standard.
What changes now
The case returns to Nevada's courts, which must now apply the correct constitutional test -- asking whether the risk of bias was too high to be constitutionally tolerable, not whether Rippo proved actual bias -- to his claim that his trial judge should have been disqualified. The Supreme Court did not decide whether recusal was actually required; that determination is left for further proceedings on remand.
What this does not decide
The Court did not decide whether the trial judge was actually biased or should have been disqualified. It only held that Nevada's courts used the wrong legal test in rejecting that claim, and sent the case back for the correct analysis to be applied.
How the Court got there
The legal reasoning, step by step
- The Due Process Clause of the Fourteenth Amendment sometimes requires a judge to step aside even without proof the judge was actually, personally biased -- the question is whether the situation created too high an objective risk of bias to be constitutionally tolerable.
- The Nevada Supreme Court instead asked whether Rippo had shown the trial judge was 'actually biased in this case,' borrowing language from a different context -- discovery requests tied to a specific 'camouflaging bias' theory raised in an earlier case, Bracy v. Gramley, where a judge was accused of hiding favoritism toward bribing defendants by ruling harshly against others.
- The Court explained that Bracy never required litigants to prove actual bias as a general matter; it simply found that the petitioner there had also pointed to facts suggesting subjective bias, which helped justify discovery in that particular case.
- Because Rippo never raised a 'camouflaging bias' theory, and because the correct constitutional question is about objective risk rather than proven actual bias, the Nevada Supreme Court asked the wrong question when it evaluated his recusal claim and his related procedural arguments.
- Applying the correct standard requires weighing all the circumstances Rippo alleged -- the judge's own indictment and the prosecuting office's apparent role in that investigation -- to decide whether the risk of bias was too high to tolerate, a question Nevada's courts have not yet properly answered.
