Lori Vallow Daybell is asking Idaho’s highest court to toss her murder convictions or send the case back for a fresh trial, arguing that a string of legal missteps undermined her basic rights. Her attorneys say the proceedings were compromised by serious errors, including the judge removing her preferred lawyer while the court was still weighing whether she was mentally competent to stand trial.

According to FOX 13, the appeal asks the Idaho Supreme Court to either overturn the May 2023 guilty verdicts outright or grant Daybell a new trial. That request is backed up by arguments laid out in a formal appellate brief that zeroes in on alleged trial-level mistakes and constitutional violations.

What the opening brief argues

The filing outlines several reasons the verdicts should be reversed, according to the Idaho Supreme Court brief. Among them: the disqualification of Daybell’s chosen attorney, alleged due process problems while her competency was still under review, and objections to the trial judge allowing evidence of uncharged “bad acts.” The brief also presses a speedy-trial claim.

Her legal team frames the counsel-of-choice issue as central, arguing that “The right protects the defendant’s autonomy, her ability to choose the advocate she trusts,” and uses that point as a key pillar in asking the high court to reverse the convictions or send the case back.

Legal stakes

The defense is leaning on a line of U.S. Supreme Court cases that treat wrongful removal of a defendant’s chosen lawyer as a serious structural problem in some trials. For background on that doctrine, see United States v. Gonzalez-Lopez (2006), where the court held that blocking a defendant’s selected counsel can, in certain situations, taint the entire proceeding.

FOX 13 reports that the appeal now sits with the Idaho Supreme Court, and it could be a long wait. It may take months, or even years, before the justices decide whether any of the alleged errors were serious enough to undo the verdicts.

Where it goes from here

The Idaho Supreme Court docket shows the appeal is active, with motions to expand the record and requests for more time already logged on the court’s website. From here, the justices will review written briefs, decide whether they need additional materials from the trial court, and potentially hear oral argument.

In the end, the court can do one of three things: grant relief and overturn some or all of the convictions, send the case back down for a new trial, or leave the existing verdicts in place. Until the court rules, Daybell remains in custody and the district court’s judgments stand.

Background

Lori Vallow Daybell was convicted in May 2023 of first-degree murder in the deaths of her daughter Tylee Ryan and her son Joshua “JJ” Vallow, and of conspiring in the death of Tammy Daybell. The case drew nationwide attention, in part because of the defendants’ fringe apocalyptic beliefs and the disturbing circumstances surrounding the children’s disappearance and deaths.
