Mission Viejo Criminal Defense Areas of Representation

Mission Viejo Criminal Defense Attorney Harvey L. Decker III has successfully defended clients in numerous high profile prosecutions, and has helped hundreds of clients obtain favorable outcomes throughout the course of his 27 years as a criminal defense lawyer.

Lawyer Harvey Decker represents criminal law defendants facing a broad range of misdemeanor and serious felony charges that include but aren’t limited to those listed below.

Misdemeanor & Felony Assault & Battery

Simple Assault (Misdemeanor)

Simple Battery (Misdemeanor)

Aggravated Battery (Felony)

Assault with a Deadly Weapon (Felony)

Assault with Great Bodily Harm (Felony)

Assault & Battery against a Law Enforcement Officer or Emergency Personnel (Misdemeanor Felony)

Mayhem or Aggravated Mayhem (Felony)

Torture (Felony)

Conviction of a misdemeanor assault & battery charge is punishable by jail time, fines, restitution or probation depending on the circumstances surrounding the alleged crime and prior criminal history or lack thereof. Conviction of felony assault & battery charges generally results in fines, restitution and time in state prison, up to a life sentence depending on the crime for which a defendant is convicted. Violent felonies such as mayhem, torture, and assault with a deadly weapon or great bodily harm are typically charged as Three Strikes cases.

Potential defenses against assault & battery include lack of intent, self-defense, and defense of other persons.

Domestic Violence – Domestic Battery charges may be brought when a battery is committed against any of the following:


Girlfriend or Boyfriend with whom the accused is cohabitating

Parent of the defendant’s children

Family Members

Former Spouse

Former Partner or Fiance(e)

Depending on the type of harm suffered by the victim, Domestic Violence may be charged as either a misdemeanor or felony offense. Penalties can range anywhere from up to one year in county jail to five years in state prison, fines, formal or informal probation, the issuance of a restraining order, community service, and mandatory counseling. The DA’s office may charge the defendant under California’s Three Strikes Law if the type of harm inflicted rises to the level of a violent felony.

Drug Crimes

Distribution of Illicit Drugs

Distribution of Prescription Drugs

Drug Trafficking



Possession of Drug Paraphernalia

Possession of Illicit Drugs

Possession of Prescription Drugs without a Prescription

Possession with intent to Distribute (Illicit Drugs or Prescription Drugs)

May be charged as a misdemeanor or felony depending on the crime for which the defendant is being charged, as well as the quantities and type of drug involved. Under Alternative Sentencing plans, those convicted of certain drug crimes may be eligible for outpatient or inpatient treatment, drug education classes, and probation.

If Alternative Sentencing is not available, penalties may range from jail time to long prison sentences, fines, and probation.

DUI & Driving Offenses – DUI and driving offenses include a broad range of offenses, including:

Driving on a revoked license

Driving on a suspended license

Driving under the Influence

Driving while Intoxicated

Driving without a license

Excessive Speeding

Hit & Run

Reckless Driving

Vehicular Manslaughter

As evidenced above, driving offenses are extremely varied, both in severity and penalties. Misdemeanor driving offenses may result in the issuance of fines, probation, participation in First Offender DUI / DUI / Substance Abuse programs, loss of driving privileges, installation of Interlock Driving Devices, and jail time.

Serious driving offenses may include fines, the loss of driving privileges, a prison sentence, and any other terms that the Court deems reasonable based on the circumstances.

Expungement of Criminal Record – Qualifying individuals may petition to court for expungement of their criminal record. Qualification requirements are as follows (and all must be met at time of filing):

Applicant is not presently being prosecuted for subsequent crimes

Applicant is not presently on probation

Applicant has never been sentenced to state prison

Applicant has successfully completed all of the terms of probation

All fines / restitution are paid in full

At least one year has passed since sentencing & applicant was not placed on probation

Criminal convictions can impede individuals attempting to secure employment or successfully complete background checks, as well as jeopardize those presently employed. An expungement serves as retroactive dismissal of all charges for which the applicant was charged. If convicted of a felony crime, Attorney Harvey Decker will file to have the felony reduced to a misdemeanor prior to seeking expungement. Those convicted of the commission of a sex crime should call us at (949) 365-7085 for additional information.

Parole & Probation Violations – Vigorous representation of those who are facing either parole or probation violations. If violated, the parolee or probationer is facing potentially severe consequences, including:

Probation Revocation

Harsher Sentence

Revocation of a Stayed Sentence

Return to Custody

Additional Prison Time

A violation may occur as the result of a simple mistake or misunderstanding. If you are in violation of the terms of probation or parole, contact the Law Office of Harvey L. Decker III immediately at (949) 365-7085.

Sex Crimes – The very allegation that a sex crime has been committed can be enough to destroy an individual’s life, let alone a conviction. Knowing how high the stakes are, Attorney Harvey Decker provides the strongest defense possible for those being prosecuted for the commission of any sex crime, including:

Child Molestation

Failure to Register as a Sex Offender


Indecent Exposure

Internet Sex Crimes

Lewd & Lascivious Conduct


Possession of Child Pornography



Sexual Battery

Sexual Crimes against Minors


Statutory Rape

A variety of defenses may be raised in sex crimes cases, including consent (rape), false allegations, and the exercise of undue influence. Most sex crimes are charged as felonies, and those convicted face penalties ranging from fines and jail time to lengthy prison sentences. Additionally violent sex crimes will be charged under California’s Three Strikes Law.  

Theft Crimes – Misdemeanor & Felony Theft Crimes

Armed Robbery



Check Fraud


Credit Card Fraud



Grand Theft

Grand Theft Auto

Identity Theft


Petty Theft

Ponzi Schemes


Theft by Fraud

Violent theft crimes are eligible for Three Strikes classification. Based on the circumstances, theft crimes are chargeable as either misdemeanors or felonies. As with previously listed crimes, if convicted the defendant may be required to pay fines, make restitution, be placed on probation, or ordered to serve time in jail or prison. If a gun was used during the commission of the crime, a firearms enhancement can lengthen the defendant’s prison sentence.

Three Strikes Cases - California’s Three Strikes Law was passed into legislation in an attempt to lengthen the prison terms for those convicted of the commission of serious, violent felonies. Under this law, a second strike conviction with double the prison sentence, and a third conviction of a qualifying Three Strikes offense will automatically result in a sentence of 25 years to life. Mission Viejo Criminal Defense Attorney Harvey Decker has represented numerous clients charged with qualifying Three Strikes offenses. Qualifying Three Strikes crimes include but are not limited to the following:

Armed Robbery


Attempted Murder

Drug Trafficking

Grand Theft





Residential Burglary

Sex Crimes against Children

Violent Drug Crimes

Violent Gang Crimes

Violent Sex Crimes

Voluntary Manslaughter

Weapons Charges / Enhancements

If you have been charged with a crime and the DA is charging the crime under the Three Strikes Law, it is crucial to retain an experienced Criminal Defense Lawyer who has extensive experience in these matters.

Violent Crimes – Violent crimes are almost exclusively charged as felonies, and are generally punishable by lengthy prison terms that may be extended if a firearms enhancement has been included. These crimes are almost always tried as Three Strikes cases. The Law Offices of Harvey Decker represents clients charged with a broad range of violent crimes, including:

Aggravated Domestic Violence

Armed Robbery


Assault with a Deadly Weapon

Assault with Intent to Commit Great Bodily Harm


Felonious Assault

Felonious Battery

Hate Crimes

Identity Theft

Insurance & Medicare Fraud

Money Laundering

Ponzi Schemes

Tax Evasion & Tax Fraud

Penalties upon conviction range from the payment of fines and restitution, to probation, jail time, and lengthy prison sentences.
