Defense for the Accused

How Our Seasoned Team of Criminal Defense Attorneys Fight for You

It’s important to recognize that your case begins the moment you are confronted by the police. Plan to consult with an attorney as soon as possible so you understand your legal rights before your arraignment date or initial court appearance. Our criminal defense lawyers will help you shape your defense and take critical steps that could make all the difference in the outcome of your case.

RaquinMercer represents defendants accused of nearly any crime, including:

  • Weapons charges
  • DUI and traffic offenses
  • Drug cases
  • Fraud and other white-collar crimes
  • Resisting arrest
  • Parole and probation violations
  • Theft and burglary
  • Murder, sexual offenses
  • And more

First degree or second degree assault, and reckless endangerment.

RaquinMercer has extensive experience handling domestic violence cases. These are cases where exposing a motive to fabricate is crucial. RaquinMercer identifies impeachment evidence and develops legal issues to protect our client’s right to confront witnesses.

Domestic violence cases have special rules, aggravating circumstances, and increased penalties. Cases scheduled on the domestic violence docket usually have a special prosecutor assigned to them. You want to make sure your attorney has seasoned experience handling these cases.

Protective orders.

The direct and collateral consequences of a protective order being entered against you can truly be devastating. You might be ordered to leave your home, and your children, pay emergency family maintenance, or stay away from your kids’ school. Effective representation is an essential part of your defense. Understand your rights before you appear at a civil protective order hearing. A violation of the protective order is a crime that carries jail time. It is important to get timely legal assistance.

Drug Cases/ Drug Court.

Drug cases range from a simple possession of marijuana to volume dealing of a controlled dangerous substance. RaquinMercer understands the difference between social use, substance abuse, and dealing to support one’s habit. Our view is that drug abuse is a public health issue and requires treatment not jail. Isabelle Raquin is the current Attorney Liaison for Drug Court in Montgomery County. She is a veteran defense attorney involved with Drug Court for the last five years. She has developed a comprehensive knowledge base of addiction issues, the available treatment needs and options, and eligibility criteria.

Our DNA is Excellence in Criminal Trials, Appeals, and Post-Conviction Proceedings.

In the years that Steve and Isabelle have practiced law, they have come to know that the power of their advocacy is a combination of two mutually reinforcing abilities. First, they effectively analyze, investigate and prepare each case for trial, appeal, or post-conviction. Second, they have the talent, technical skills, and experience necessary to present their client’s side of a case persuasively during trial, in an appellate brief, or at a post-conviction hearing. It is the reinforcing effect of their combined abilities to effectively prepare a case and execute on a plan of representation that results in great advocacy. Steve and Isabelle approach their representation of each client with the firm belief that effective advocacy is both an art and a skill that is only mastered in an individual case through complete preparation and precise execution. This is why a person accused or convicted of a crime should retain RaquinMercer for representation at trial, appeal, or post-conviction.


Judge and jury trials are the principle way to resolve an accusation that a person has committed a crime. Although most criminal accusations are resolved through a plea-bargaining process, judge and jury trials remain the most important method for resolving a factual dispute whether an accused has committed a crime. In another sense, an attorney’s reputation as a trial attorney can make the difference to whether a prosecution ever goes to trial.

In our adversarial system, the defense is pitted against the prosecution and each side presents their version of the truth. In a jury trial, the judge gets to decide legal questions, the jury must decide factual questions, and then apply the law to the facts. To prevail at trial, the defense has certain tools available to it, such as the substantive law of the crime, the rules or procedures of the court, the technical rules of evidence, and the art or psychology of persuasion. Fully integrating these tools at trial is what RaquinMercer is all about.

In our system of criminal justice, overreaching police officers and overzealous prosecutors can tilt the balance of advantage against you. You need a seasoned trial team on your side to shift the balance in your favor. You have rights that need to be protected and a liberty interest that must be defended. RaquinMercer fights for you, for your rights, and for your future.

Appellate advocacy is a specialized area of practice that is unfamiliar to many trial lawyers. Steve has 20 years of successful appellate experience, primarily in Maryland state appellate courts, but also in the D.C. Court of Appeals, the Fourth Circuit Court of Appeals, and the United States Supreme Court. You can read here a recent appellate decision in a case successfully briefed and argued by Isabelle.

Most trial lawyers lack an understanding of the procedures of an appellate court, or how doctrinal principles shape and define the contours of appellate review. At the same time, many appellate attorneys lack the experience of jury trials, which limits their insight of the trial process. Steve and Isabelle believe that combining the art of appellate advocacy and the art of trial advocacy has a mutually reinforcing and amplifying effect on the quality of representation they provide to their clients. Trial experience, in particular mastering the art and psychology of telling a persuasive narrative, is an essential tool in an appellate practice. Also, knowledge of the appellate process is a critical part of honing legal arguments during a trial. RaquinMercer commits to both.
