Questioning child abuse witnesses

1. Whether the Confrontation Clause of the Sixth Amendment prohibits a trial court from restricting cross-examination regarding a complaining witness's bias, motive to fabricate, and prior false accusations by limiting inquiry to a single question without extrinsic evidence, where the witness's credibility is central to the prosecution and the defense has a good faith basis for the line of questioning. 2. Whether a conviction may stand under the Due Process Clause of the Fourteenth Amendment when the trial court admits opinion testimony on sociological issues of delayed disclosure patterns in child abuse cases under the rubric of "lay" testimony and thereby circumventing the qualification, disclosure, and testing requirements applicable to expert testimony where the testimony's probative force depends entirely on specialized knowledge rather than everyday reasoning. 3. Whether appellate review comports with due process when an appellate court affirms a conviction by relying on the absence of evidence where that absence resulted from the trial court's evidentiary rulings that shaped the record available for closing argument and appellate review.
