Viktoria V. Devai v. John M. Burk, 53351

The Idaho Supreme Court affirmed a magistrate court order modifying a high-conflict custody arrangement between Viktoria Devai and John Burk concerning their six-year-old child. 1
The parties’ prior decrees awarded joint legal and physical custody, and Devai later sought to maintain or restrict Burk’s parenting time while Burk sought increased custody. 2
During the modification case, multiple IDHW investigations, a parenting time evaluator, and a GAL each found no substantiated child abuse by Burk and reported the child was safe in his care. 3
After an eight-day trial, the magistrate court found a material change in circumstances, rejected Devai’s abuse allegations, and ordered week-on, week-off joint custody with counseling and coordination provisions. 4
The court also authorized a staged process for school selection if the parents could not agree, including limited authority for Burk to select a school within either home district. 5
Devai appealed, challenging the domestic-violence and child-abuse findings, the school-selection ruling, and the court’s reliance on the parenting time evaluation. 6

Issue	Plaintiff's Argument	Defendant's Argument	Held
Did the court properly reject domestic-violence findings? 7	Devai said Burk’s past conduct and protection orders proved domestic violence.	Burk argued the conduct was historical and not statutory domestic violence.	No abuse of discretion; no domestic violence as defined by Idaho law. 8
Was there substantial evidence Burk did not abuse the child? 9	Devai relied on child disclosures, photos, weight concerns, and videos.	Burk cited IDHW, GAL, and evaluator findings rejecting abuse.	Yes; substantial and competent evidence supported no abuse finding. 10
Did the school-selection provision improperly delegate custody authority? 11	Devai claimed Burk’s fallback school-selection power was retaliatory and unsupported.	Burk argued the child had no established school and the order preserved joint custody.	No; limited delegation and unilateral enrollment ruling were permissible. 12
Was reliance on the parenting time evaluation improper? 13	Devai argued the evaluator was biased and incomplete.	Burk argued the evaluator was neutral and the report complied with Rule 1004.	No; the neutral evaluation was proper and reasonably weighed. 14
Was the judicial-bias issue preserved on appeal? 15	Devai accused the magistrate judge of bias and retaliation.	Burk argued the issue was not properly raised or supported.	No; the bias issue was waived. 16
