COMLAB sued Kal Tire in the Southern District of New York and produced printed emails and invoices it said supported its contract claim. Kal Tire disputed the documents and requested native versions. COMLAB said the native email data was gone because a computer virus led its president to wipe the machine. The court held an evidentiary hearing on fabrication and spoliation.
GDF's assignment
Kal Tire retained Joseph Caruso of Global Digital Forensics to examine the virus explanation and the metadata and technical characteristics of the disputed material. The work addressed whether the supplied account was consistent with the artifacts and system behavior. Caruso testified at the hearing and was cross-examined.
What the public decision records
The court found clear and convincing evidence that COMLAB fabricated the disputed emails and spoliated evidence to conceal the fabrication. It granted terminating sanctions, dismissed the action with prejudice, and ordered payment of Kal Tire's reasonable fees and costs. The opinion describes Caruso's experience and testimony favorably and explains why the court credited his technical account over the competing explanation.
Case outcomes turn on their own facts, law, witnesses, and evidence. This result does not predict another matter.
Practice lesson for counsel
When authenticity is disputed, preserve native files, full headers, source devices, mail-server records, and the steps used to create any PDF or printout. Test alternative explanations before the hearing. A technically plausible story must still fit the actual metadata, chronology, and system state.
