Background
Craig Peed suffered serious injuries in 2012 when a falling tree limb struck his head while he worked for Essential Staffing, Inc. After his upper teeth began fracturing years later, the Industrial Accident Board found in 2018 that the workplace accident caused damage to upper teeth nine through eleven, and Essential Staffing’s workers’ compensation carrier paid for their treatment.
In 2023, Peed sought additional compensation after his lower teeth became severely worn. His dentist, Dr. Arvind Jain, attributed the deterioration to friction from the crowns installed on Peed’s upper teeth and to a lack of dental care while Peed was comatose after the accident. Essential Staffing’s expert, Dr. Barry Berman, disagreed and attributed the lower-teeth problems to preexisting decay, among other factors.
The IAB credited Dr. Berman, found that Peed had not proved a causal connection between the accident and the lower-teeth treatment, and denied benefits. The Superior Court affirmed, rejecting Peed’s arguments concerning the IAB’s earlier findings, the sufficiency of the evidence, and the Board’s failure to expressly rule on his objection to portions of Dr. Berman’s deposition testimony.
The Court’s Holding
The Delaware Supreme Court affirmed. It held that collateral estoppel did not require the IAB to apply its 2018 causation findings to Peed’s later lower-teeth claim. The earlier proceeding determined causation for damage to particular upper teeth, while the later proceeding presented a different issue: whether the accident caused the deterioration of Peed’s lower teeth. The 2025 decision also did not retroactively alter the earlier award.
The Court further held that substantial evidence supported the IAB’s decision. The Board was entitled to credit Dr. Berman over Dr. Jain, particularly because Dr. Jain relied on photographs taken after root-canal procedures had required grinding Peed’s teeth to the gum line. Dr. Berman had reviewed Dr. Jain’s treatment notes and deposition and had personally examined Peed.
Although the Court said the IAB generally should address parties’ objections, it held that the failure to expressly rule on Peed’s objection did not deprive him of a fair hearing. The challenged testimony was in the record, responded to newly learned information, and was subject to cross-examination. The Board therefore did not abuse its discretion by considering it.
Key Takeaways
- An IAB causation finding concerning injury to particular teeth does not necessarily preclude later litigation over whether the same accident caused damage to different teeth.
- Substantial-evidence review permits the IAB to choose between competing experts when it identifies record-based reasons for its credibility determination.
- An IAB should ordinarily rule on evidentiary objections, but failure to do so does not require reversal when the challenged evidence is in the record, subject to cross-examination, and its consideration does not make the hearing unfair.
Why It Matters
The decision limits the preclusive reach of earlier workers’ compensation findings when a claimant later seeks benefits for a distinct condition. Even when the conditions involve the same accident and a related part of the body, collateral estoppel applies only if the issue previously decided is identical to the issue presented later.
The ruling also underscores the IAB’s procedural flexibility. An unaddressed evidentiary objection may not warrant reversal when the reviewing courts can examine the record and determine that the claimant had notice, an opportunity for cross-examination, and a fair hearing.
