The record

In affirming a judgment in a particular mesothelioma action, the California Court of Appeal recounted trial evidence about Colgate and McCrone testing of named talc materials and finished-product samples in 1974, 1976, and 1984.

Claim scope

A published appellate opinion’s account of contested trial evidence in one named case, including the testing descriptions presented at trial.

What this source does not establish

That every recounted test result was independently verified by the appellate court, the composition of every product, a universal contamination conclusion, individual causation outside that case, or liability for other parties.

Limitations

The opinion also recounts Colgate’s laboratory-contamination explanation and McCrone’s caveat that one tremolite fiber may have been stray contamination. Those caveats are part of this record’s meaning and remain adjacent to any positive-testing description.
