What each side argues
Kansas (Petitioner)
According to Stephen R. McCallister, the petitioner argues that voluntary statements obtained in violation of constitutional standards may be used for impeachment when the defendant testifies at trial.
According to Nicole A. Saharsky, the petitioner (through amicus counsel) contends that the rule allowing such statements for impeachment should apply in this case.
According to MS. SAHARSKY, the petitioner argues that excluding the evidence would impose a strong price on the government, citing prior cases such as Havens, Walder, Harris, Hass, and Harvey.
According to Stephen R. McAllister, the petitioner argues that the balancing of interests in Sixth Amendment cases is a modest consideration, referencing Nix v. Williams and Michigan v. Harvey.
Donnie Ray Ventris (Respondent)
According to MR. EDGE, the respondent argues that the Sixth Amendment violation at issue is a core enumerated trial right, making it a distinct matter from other cases.
According to MR. EDGE, the respondent contends that allowing the evidence would remove any disincentive for police to obtain such evidence improperly.
What happened at oral argument
Justice Scalia asked when the Sixth Amendment violation occurs.
Justice Ginsburg asked whether it would make no difference if a police officer pretended to be a cellmate.
According to JUSTICE SCALIA, justice Scalia later questioned whether the Court would be allowing a constitutional violation, referencing the Miranda situation.
Justice Alito asked whether there was a dispute that a Sixth Amendment violation occurred at the time the statement was taken.
According to Justice Ginsburg, justice Ginsburg inquired about a fallback approach and the need for a judicial determination of intentional false testimony.
Justice Stevens asked whether the rule would apply equally for statements made under oath.
