Sentis Group, Inc. v. Shell Oil Co., 763 F.3d 919

Plaintiffs Sentis Group, Inc. and Coral Group, Inc. sue Shell Oil Co. and Equilon Enterprises under contract, fraud, Missouri franchise laws, and the PMPA related to a cluster of gas-station sites around Kansas City.
On prior appeal, we reversed a dismissal and remanded for reconsideration; on remand the district court found Plaintiffs controlled and failed to preserve evidence.
The district court sanctioned spoliation and dismissed with prejudice, citing Plaintiffs' ongoing evasive conduct and loss of irreplaceable data from Anton's computer.
Anton, Plaintiffs' accountant, disappeared with his computer; evidence included financial data, payments to Anton, and related documents; Walls expert was excluded (sanctioned but not appealed).
The court concluded the loss of Anton's computer and its raw data caused irreparable prejudice, supporting a dismissal sanction.
On appeal, we review for abuse of discretion but uphold dismissal as within the range of permissible sanctions given the history and surprising losses.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether dismissal with prejudice was an abuse of discretion	Sentis contends the record shows non-exclusive, non-deliberate failures to preserve evidence not amounting to willful spoliation.	Shell/Equilon argue a pattern of evasive conduct and loss of irreplaceable data justifies dismissal.	No abuse; dismissal affirmed as permissible sanction.
Whether the loss of Anton's computer constitutes irreparable prejudice	Sentis argues other evidence could recreate records; computer loss alone is not irreparable.	Defendants assert Anton's computer contained unique data impossible to replace, causing irreparable prejudice.	Irreparable prejudice supported; dismissal proper.
Whether the court properly treated Anton's disappearance as part of a broader pattern justifying sanctions	Sentis maintains the focus was on isolated issues, not broader misconduct.	Defendants emphasize ongoing suppression and misrepresentation, showing a pattern warranting severe sanction.	Pattern of misconduct supports dismissal.
Whether the deposition termination relating to Anton affected spoliation findings	Sentis contends termination did not equate to spoliation given later discovery.	Defendants argue continued need for evidence and new disclosures after deposition termination justified spoliation concerns.	Termination did not defeat ultimate spoliation finding; prejudice remained.
