Lacaze v. Louisiana

(1) Whether, under McDonough Power Equipment, Inc. v. Greenwood, "a valid basis for a challenge for cause" requires a showing that a correct response would have subjected the juror to mandatory or per se disqualification, or whether it requires a showing that a hypothetical reasonable judge would have granted a motion to dismiss the juror for cause; (2) whether the McDonough test applies only in cases of deliberate dishonesty by the juror or whether it applies also in cases of misleading omissions; and (3) whether a trial judge's involvement as a witness in a police investigation before and during trial, and his failure to even disclose it, creates an "unconstitutional potential for bias" under Williams v. Pennsylvania.
