Name: People v. Cook
Case #: S042659
Court: CA Supreme Court
District CalSup
Opinion Date: 05/17/2007

Once a scientific procedure is determined to be accepted in the scientific community, as set forth by the criteria established in People v. Kelly (1976) 17 Cal.3d 24, variations in technique or procedure used in the testing is an issue that goes to the weight of the evidence rather than its admissibility. Admission of results of electrophoretic testing of dried blood stains is proper in that it meets the Kelly criteria.
