Depositions and Trial Testimony (DATTA)

DATTA contains transcripts and exhibits from smoking and health-related litigation. A majority of the transcripts and depositions were collected from a variety of sources by the Tobacco Research Network, University of Michigan, Ann Arbor. Transcripts are unedited and in their original form. Some are rough copies and others may be marked as "confidential" although they no longer retain that status.

• A small subset of the documents come from litigation in the 1990s re: the violation of California’s Proposition 65, also known as the Safe Drinking Water and Toxic Enforcement Act. Prop 65 requires the State to maintain a list of chemicals known to cause cancer or reproductive harm in humans. When hazardous doses of those chemicals are present, companies are required to notify the public, usually in the form of warning labels and signs.
• Another small set of trial exhibit videos come directly from the now-closed Minnesota Tobacco Documents Depository.
