Founder of The Chastaine Law Office

In 2007, Mike Chastaine opened The Chastaine Law Office, putting over three decades of criminal law expertise to work on behalf of those who have been accused of criminal misconduct in the many counties and communities surrounding Sacramento, in Northern California. Prior to that, Attorney Chastaine served 11 years as a Deputy Public Defender for Santa Clara County and worked for five years in the county’s Alternate Defender Office before serving for six years as “of counsel” to a well-respected private practice firm in Sacramento.

Over the years Attorney Chastainehas developed a reputation as one of Sacramento’s best sex crime lawyers. Few lawyers have the trial experience that Attorney Chastaine brings to the representation of his clients. For three decades he has served as a criminal defense attorney, he has tried scores of jury trials in numerous counties, in both state and federal court, and has obtained many not guilty verdicts.

Reported Cases

Reported cases are judicial opinions certified for publication or ordered to be published by the court. These cases establish precedents in the judicial system and may be cited or relied on by courts and parties in future cases. Reported cases that Michael Chastaine has been involved in include People v. Jenkins, which was instrumental in resolving questions surrounding the application of the state’s habitual offender sentencing and three-strikes laws to people convicted of murder.

Michael represented the petitioner in Moore V. Superior Court, where the Third District Court of Appeals fixed the five-year “washout period” in Proposition 36 as dating from the time of the commission of the previous felony as opposed to the time of conviction, thereby increasing the chances for a person to qualify for drug treatment and probation instead of incarceration under Prop 36.

Jury Trials

Michael Chastaine won five jury trials in a row, an exceptional record which is highly unusual in the field of criminal defense. Some of the successes of The Chastaine Law Office include findings of “not guilty on all counts” of a Placer County massage therapist charged with multiple counts of sexual battery, and a taxi driver charged with rape of an intoxicated person. Attorney Chastaine also had juries return not guilty verdicts in two separate San Joaquin County cases involving charges and accusations of child molestation, and in a Sacramento County case of a businessman charged with battery. Also, in Solano County, Attorney Chastaine defended a school teacher charged with multiple counts of child molestation in a case which resulted in a mistrial/hung jury followed by a favorable settlement. Hung juries in Yolo County lead to a misdemeanor, no jail, no registration outcome for a man facing life in prison. These are just some of the recent outcomes of cases.

Record Clearance and Other Favorable Dispositions

Attorney Chastaine believes that everyone deserves a second chance. To facilitate that goal, Mike has established a strong practice involving criminal record clearance. He has obtained numerous Certificates of Rehabilitation in various counties for persons with prior sex offenses, thereby eliminating their requirement to register as a sex offender. The firm also recently persuaded the district attorney to dismiss a failure-to-register-as-a-sex-offender case due to a mistake of fact.

The Chastaine Law Office has:

  • Secured a certificate of factual innocence regarding a client identified as a person who threw a beer bottle at a woman
  • Obtained a very favorable federal sentence for a client who possessed weapons after suffering drug sales convictions
  • Obtained a full dismissal on a very complex elder abuse fraud case based upon establishing that the complaining witness was lying
  • Proved in a federal marijuana-growing case that included an officer-involved shooting that the police officer was shot with friendly fire, saving the client 10 years in prison
  • Obtained a sentence of probation in a federal prosecution of a medical marijuana grower.
  • Obtaining well below guideline sentences for persons charged with child pornography.
  • Successfully sued the California Parole Division for false imprisonment of a client.
  • Obtain dismissal of many cases, including a child moles case where the client was facing a life sentence
