Phillip Baker served on the civil defense team alongside his father, lead attorney Robert Baker, representing O.J. Simpson throughout the trial. He participated in key depositions — including those of Kato Kaelin, Simpson himself, and Denise Brown — and took an active role at trial, most notably in an aggressive cross-examination of FBI footwear expert William Bodziak, where he challenged the methodology behind the Bruno Magli shoe print evidence and pressed on the prosecution's failure to provide crime scene materials for comparison.
