In October, we wrote about Michael Robinson, a defendant who requested the software behind the DNA analysis tool used to identify Robinson as the perpetrator of a double-homicide. An expert witness, Dr. Perlin, who developed the technology, is expected to testify in the case. Dr. Perlin told the judge that releasing this information would cause irreparable harm to his company.Defense attorneys had argued that the defendant had the right to confront the validity of the results that the software generated.  The judge denied the defendant’s request without issuing a written opinion.
