Brookshire Bros. v. Aldridge: When Intent Matters More Than the Missing Evidence

The case

Brookshire Bros., Ltd. v. Aldridge, 438 S.W.3d 9 (Tex. 2014), addressed when Texas courts could give adverse-inference jury instructions for missing evidence. The plaintiff sought an instruction telling jurors they could infer the missing evidence would have been unfavorable to the defendant. The Texas Supreme Court rejected this approach for cases involving negligent or accidental destruction.

What the court held

The court limited adverse-inference instructions to cases of intentional spoliation. Mere negligence or routine destruction doesn't justify telling a jury to assume the missing evidence would have hurt the destroying party. This aligned Texas state practice with the direction federal courts were moving, which the 2015 FRCP 37(e) amendments later codified by requiring "intent to deprive" for the harshest sanctions.

Where blockchain anchoring fits

Intent separates sanctionable spoliation from ordinary document loss. Courts need objective evidence to distinguish between "we lost it accidentally" and "we destroyed it on purpose." A SHA-256 hash anchored to Polygon and Bitcoin creates an immutable timestamp proving when a file existed. If the anchor shows the file existed after the litigation hold began, then disappeared, that timeline evidence helps establish intent. The blockchain record can't be altered retroactively. It exists independently of the file itself. Even if opposing counsel claims "the server crashed" or "it was routine deletion," the anchor proves the file survived past specific dates. This objective timeline helps courts apply the Brookshire standard. Without timestamps, intent arguments become pure credibility contests. With blockchain anchors, there's verifiable evidence of when preservation was possible but didn't happen.

The takeaway for practitioners

Document your preservation timeline before the dispute begins. FRCP 37(e) and state rules following Brookshire require intent evidence for serious sanctions. FRE 901(b)(9) allows authentication of blockchain timestamps as evidence from "a process or system that produces an accurate result."
