The Rule of Fisher v. Fisher is that intentional infliction of emotional distress can be the legal cause of a wrongful death when the tortious conduct is a substantial factor in causing severe emotional distress that leads to the victim's death, under the broader scope of liability standard applicable to intentional torts rather than the narrower "scope of risk" standard used for negligence.

The Rule of Chapman v. Avon Products is that expert testimony about asbestos testing methodology is admissible when the witness demonstrates sufficient knowledge, skill, experience, or training to interpret test results relevant to their field of expertise, under circumstances where the expert relies on established scientific principles even if using older or modified techniques.
