What others have said about Hon. Marta S. Diaz



Comment #: CA15979
The only judge I ever seen to walk out of court room to resolve the issue herself. She did not take the word of the cops and investigated herself.
The cop made up the stop was legal because the car exhaust was so loud and all hell broke lose after that, Became full blown search without consent and said to find some prescription drugs in the trash bag. If the judge is like any others who think the cops are the honest guys, I will become another contract they fulfilled. We need more reasonable judges like Judge Martha Diaz.


Comment #: CA7374
Judge Diaz sent juvenile boys to child psychiatrist Dr. William Ayres after she knew the San Mateo Police Department was investigating him for molesting boys in 2002. According to the San Mateo DA, Diaz actively tried to get the police to stop investigating Ayres because she said they were friends and she was sending boys to him. At least one juvenile she sent to Ayres in 2003 has come forward to say he was assaulted. Even worse: for a judicial profile for the San Francisco Daily Journal in 2009 about her association with Ayres, Diaz stated (verbatim)"It's all bullshit." She stated that anyone who complained about her had a "jihad" against her. She was privately sanctioned by the California Commission on Judicial Performance for her remarks. Many, many parents of boys who found themselves in juvenile court have been aghast at her injudicious remarks and her angry chip on her shoulder against boys in particular
