## Facts

- Lisa Ann Thomas brought an action on behalf of her minor son, A.T., a student with disabilities eligible for a free appropriate public education (FAPE) under the IDEA.
- Thomas filed an IDEA due process complaint challenging the adequacy of the District of Columbia Public Schools’ (DCPS) special education services and placement for A.T.
- The administrative hearing process experienced delays and postponements attributable in part to the hearing officer and in part to Thomas (including scheduling-related issues).
- The impartial hearing officer ruled for DCPS on the merits and later denied Thomas’s motion for reconsideration.
- Thomas sought judicial review in federal district court, primarily arguing that the hearing officer lacked impartiality and that the administrative decision should be set aside for bias.
- The asserted grounds for bias included: the hearing officer’s handling of delays and procedure, denial of reconsideration, alleged legal error, alleged ex parte communications with DCPS, and an alleged employment or dependent relationship with the District.
- The parties filed cross-motions for summary judgment.

## Issues

1. Whether Thomas produced convincing, record-based evidence that the IDEA hearing officer was biased or not impartial, requiring the administrative decision to be set aside.
2. Whether alleged legal error by the hearing officer, alone or combined with other circumstances, can establish bias sufficient to invalidate the decision.
3. Whether delays, case-management decisions, and denial of reconsideration deprived Thomas and A.T. of the fair and impartial hearing required by the IDEA.

## Decision

- The court granted summary judgment for the District of Columbia and denied Thomas’s motion for summary judgment.
- The court affirmed the hearing officer’s administrative decision.
- The court held Thomas did not overcome the presumption that an administrative adjudicator is impartial.
- The court found that delays and scheduling problems, without prejudice affecting the ability to present the case, did not show bias.
- The court held that denial of reconsideration and alleged legal error were substantive rulings and did not, without more, demonstrate partiality.
- The court rejected the bias theory based on alleged ex parte communications and the hearing officer’s relationship with the District because the record lacked substantiated evidence of a disqualifying conflict or prejudgment.

## Legal Principles

- IDEA requires an impartial hearing officer, but administrative adjudicators are presumed unbiased; the party alleging bias bears the burden to rebut that presumption with convincing evidence.
- Adverse rulings, credibility determinations, and even mistaken legal conclusions generally do not establish bias absent evidence of animus, prejudgment, or a disqualifying interest.
- Procedural delays and case-management irregularities support relief only if they materially prejudice a party’s ability to present evidence or arguments, not merely because they occurred.
- Allegations of ex parte communications or conflicts must be supported by specific record evidence showing improper influence or an interest tied to the case’s outcome.
- In IDEA judicial review, the court independently reviews the administrative record while giving due weight to the hearing officer’s findings.

## Conclusion

The court affirmed the IDEA hearing decision because Thomas’s bias allegations—based on delays, denial of reconsideration, asserted legal error, and unsubstantiated claims of ex parte contacts or conflicted status—did not provide convincing evidence overcoming the presumption of an impartial administrative adjudicator, nor did they show prejudice amounting to denial of a fair hearing.
