On November 1, 2007, the California Supreme Court dismissed an appeal in this case, thereby preserving the defendants’ victory in the appeals court on an important issue involving expert testimony. The proceeding involved claims by former workers at a Lockheed aerospace plant that their exposure to five solvent chemicals in the workplace caused them to become sick with cancer. The plaintiffs sought to present an expert witness to testify that their cancer was, in fact, caused by those chemicals. The issue before the California Supreme Court was the admissibility of the testimony of that witness where none of the articles and other materials on which he relied demonstrated a link between the chemicals involved and cancer in humans. Dismissal of the appeal was a victory for WLF, which filed a brief urging affirmance of the lower courts’ decisions to exclude the testimony.
