Ohio v. Reiner: Innocent Witnesses and Batt’s Privilege

In Ohio v. Reiner, 532 U.S. 17 (2001), the U.S. Supreme Court unanimously held that a witness who insists she is innocent can still invoke the Fifth Amendment privilege against self-incrimination. The per curiam opinion, issued March 19, 2001, reversed the Supreme Court of Ohio, which had ruled that a denial of wrongdoing forfeits the privilege. The Court’s answer was direct: it had never held any such thing, and the privilege protects innocent witnesses whose truthful answers could still supply evidence against them.¹

The Rule the Court Announced

A witness may claim the Fifth Amendment if she has “reasonable cause to apprehend danger from a direct answer.” She does not have to admit anything first. The Court wrote: “We have never held, as the Supreme Court of Ohio did, that the privilege is unavailable to those who claim innocence.”¹

Two earlier decisions carried the reasoning. Hoffman v. United States, 341 U.S. 479 (1951), had established that the privilege reaches any testimony that could “furnish a link in the chain of evidence needed to prosecute” the witness, even if the testimony alone would not support a conviction.²¹³ A truthful answer from someone who did nothing wrong can still hand the government the pieces it needs.

How the Case Reached the Court

Matthew Reiner, an engineer living in the Toledo, Ohio, area with his wife and three young children, was charged with involuntary manslaughter after the death of his two-month-old son Alex. Alex died on August 30, 1995, two days after becoming unresponsive at home. The Lucas County Coroner concluded the cause was shaken baby syndrome and estimated the fatal injury had occurred within minutes of the child’s respiratory arrest. Alex also had a broken rib and a broken leg. His twin brother Derek had three broken ribs.⁴

Only two adults had extended solo time with the twins during the relevant window: Reiner and Susan Batt, the family’s 24-year-old babysitter, who had been the twins’ exclusive daytime caregiver since August 14. Defense experts disputed the coroner’s tight timeline and said the injuries could have been inflicted hours earlier, when Alex was in Batt’s care. The trial became an either/or contest: father or babysitter.⁵

Batt refused to testify without protection and signaled she would invoke the Fifth Amendment. At the prosecution’s request, the trial court granted her transactional immunity under Ohio Revised Code Section 2945.44.⁶ She then took the stand, denied ever shaking or harming either child, and said she had not known about any broken bones. The jury convicted Reiner on September 23, 1996.⁴

The Ohio Court of Appeals reversed, and the Supreme Court of Ohio affirmed the reversal. The state high court reasoned that because Batt denied any involvement, she had no valid Fifth Amendment privilege to begin with. An innocent person, in its view, cannot incriminate herself, so the immunity grant was unlawful and prejudicial to Reiner. That is the ruling the U.S. Supreme Court took up.⁷

Why Batt’s Privilege Was Valid

Applying Hoffman and Grunewald, the Court found Batt plainly had reasonable cause to fear incrimination. She had been the twins’ sole caregiver for much of the period when the injuries could have occurred. The entire defense case was that she, not Reiner, had shaken Alex. If she conceded on the stand that she was alone with him during the relevant hours, that admission alone could supply a link in any future prosecution against her. Her insistence that she was innocent did not remove the danger. It described exactly the situation Grunewald had in mind: an innocent witness whose truthful answers could be turned against her by ambiguous circumstances.⁷

What Happened on Remand

The federal ruling settled the Fifth Amendment question but not the state-law question of whether the trial court had properly granted immunity. On remand, the Supreme Court of Ohio issued a new decision on November 28, 2001. It accepted that Batt held a valid privilege, then reversed Reiner’s conviction on a different ground: the immunity grant was an abuse of discretion because it “did not further the administration of justice” and “severely prejudiced the rights of the defendant.”⁸

The court’s concern was structural. When culpability is split between two people and only one is on trial, immunizing the other can “actually hinder the search for truth.” The immunity order signaled to the jury that the state had cleared Batt, and it kept the jury from seeing her assert her right to silence, a spectacle that might have cut against her credibility and supported the defense theory. The court held that if the state retried Reiner, Batt would be permitted to invoke the Fifth Amendment.⁸

Why the Decision Matters

Reiner is short, unanimous, and settles a point that had been treated as unsettled by at least one state supreme court: the privilege against self-incrimination is not a confession-in-disguise. A witness does not concede guilt by asserting it, and a court cannot strip the privilege from a witness who says she did nothing wrong. The standard is reasonable cause to fear that an answer could contribute to prosecution, and that fear can coexist with actual innocence.⁹

The decision also cuts against the common view that the Fifth Amendment exists mainly to shield the guilty. Legal commentator Sherry Colb noted that the privilege is usually litigated in the context of suppression motions that keep damaging evidence out, which reinforces the impression that only wrongdoers benefit. Reiner highlights the opposite function, protecting innocent people from being made, as Colb put it, “instruments of their own criminal convictions.”¹⁰

Within Ohio, the remand decision has separately shaped how prosecutors use witness immunity under R.C. 2945.44. Courts treat immunizing an alternative suspect in an either/or case as a red flag for abuse of discretion.¹¹
