For many people convicted of drug crimes, a change in the law or the discovery of new evidence can provide a lifeline.
In recent years, criminal law has evolved through key courts’ rulings—including decisions by the Washington State Supreme Court and even the Supreme Court—that have opened the door to overturning drug crime convictions.
If you or someone you know has prior convictions for simple possession or other drug-related offenses, it is crucial to understand when you may be eligible to seek relief and what legal strategies can help.
Why Drug Crime Convictions Are Being Overturned
Changes in criminal law sometimes make past convictions unconstitutional. For example, the Washington State Supreme Court ruled that the state’s felony drug possession law was unconstitutional because it did not require proof of intent to possess drugs. The court specifically found that the relevant article of the Washington criminal code governing drug possession felonies was unconstitutional.
When a court issues such a ruling, it can affect criminal cases where people were found guilty years ago, leading to dismissed charges or reduced sentences. The court’s decision covered individuals convicted under the unconstitutional statute, including those with felonies for drug possession. These convictions have impacted people for decades, affecting employment, housing, and other opportunities. The ruling also impacts prior convictions, which can influence sentencing and collateral consequences in future cases. It remains to be seen what will happen next, as legislative or judicial responses may further clarify the scope of relief. We can also expect other jurisdictions or counties to consider similar actions in response to this precedent.

Introduction to Criminal Conviction Overturns
Overturning a criminal conviction is a critical process for anyone who believes they have been wrongfully convicted or treated unfairly by the courts. In the United States, the justice system offers several pathways to challenge a conviction, whether at the state or federal level. For example, individuals convicted in federal court can file a 2255 writ of habeas corpus, which allows them to appeal their conviction and seek a new review of their case. State courts also provide options for post-conviction relief, giving people the chance to present new evidence or argue that their rights were violated during the original trial. Understanding these processes is essential for anyone seeking to appeal a criminal conviction and pursue justice. Each step in the process—from filing an appeal to presenting new evidence—can make a significant difference in the outcome for those convicted.
The Role of New Evidence
In some criminal cases, the key to overturning a conviction is the presentation of new evidence. Here are some examples of new evidence that could lead to overturning a conviction:
- Witnesses who were previously unavailable.
- Police misconduct was uncovered after the trial.
- Prosecution errors that violated due process.
- Forensic testing that disproves earlier claims.
- A new statement from a witness or the defendant that was not previously disclosed.
At this point, it is important to note that only certain categories of new evidence, such as those listed above, qualify for post-conviction relief under the law.
If new evidence creates a reasonable doubt, a judge may grant a new trial or even order the conviction overturned.
How Supreme Court and Federal Court Rulings Affect Drug Convictions
Both the Supreme Court and federal court systems influence how criminal convictions are reviewed. A significant court’s ruling can create precedent that state courts must follow, especially in cases involving constitutional rights.
When prosecutors rely on outdated or invalidated laws, a defendant can pursue relief through the appeal process or by filing a petition for post-conviction review. A successful appeal or petition can reverse a criminal conviction, providing relief for the defendant.
State-Level Overturns and the Washington State Supreme Court
The Washington State Supreme Court has played a pivotal role in reshaping how simple possession convictions are handled. In the landmark State v. Blake decision, the court found that it was unconstitutional to convict a person of possession of controlled substances without proving they were aware of the possession. This Supreme Court ruling led to the dismissal of thousands of simple possession convictions across Washington State. Prosecutors have responded by dropping pending cases, and courts have begun to automatically vacate simple possession convictions for individuals still in custody. The court’s decision applies retroactively, meaning that anyone convicted under the old law can benefit from this change. Unless the U.S. Supreme Court intervenes, this ruling stands as a powerful example of how state courts can correct past injustices and ensure that only those who are truly aware of their actions are held accountable.

Appeals and Post-Conviction Relief
An appeal is a request for a higher court to review the outcome of your case. The person appealing is the subject of the conviction and sentence. In drug crime appeals, your defense attorney may argue that:
- The law used in your trial was unconstitutional.
- Evidence was improperly admitted or excluded.
- The jury was misinstructed.
- There was misconduct by the prosecution or police.
If successful, the conviction may be overturned, and the subject may no longer be sentenced to prison or other penalties, your sentence reduced, or the case dismissed entirely.
Filing a Petition for Relief
Even if your time for a standard appeal has passed, you may still file a petition for post-conviction relief. This legal proceeding allows the court to review your record, consider new law or new evidence, and decide whether your conviction should be vacated. Reviewing case records is essential to determine eligibility for relief.
For drug crimes, petitions are especially effective when a court’s ruling has changed the definition of the offense, such as removing certain possession charges from the law entirely. Individuals who were possibly affected by the old law may now be eligible for relief.
Common Grounds for Overturning Drug Crime Convictions
You may be eligible to have your conviction overturned if, under a specific legal provision such as Article 930.3 of the Louisiana Code of Criminal Procedure, one of the following applies:
- A new law decriminalizes your offense.
- A court’s ruling declares the statute unconstitutional.
- New evidence undermines the prosecution’s case.
- Police engaged in unlawful searches or seizures.
- The jury was misled or improperly instructed.
- There was misconduct by prosecutors.
The Importance of Transparency and Accountability
Transparency and accountability are the cornerstones of a fair criminal justice process. The Washington State Supreme Court’s decision to overturn thousands of simple possession convictions demonstrates a commitment to justice and the need for clear, honest prosecution. When courts and prosecutors are transparent about the evidence and the process, it helps ensure that convictions are based on solid proof and not on flawed procedures. The situation in Massachusetts, where a state drug-testing laboratory’s misconduct led to the reversal of many convictions, further highlights the importance of accountability. By overturning convictions tied to unreliable evidence, the courts are taking steps to restore public trust and uphold the integrity of the justice system. Ultimately, these actions show that when the process is open and accountable, it is possible to correct mistakes and deliver true justice for those affected.
The Impact on Sentences and Custody
If a conviction is overturned, the sentence imposed on the defendant may be nullified. This could lead to the defendant’s immediate release from prison or the clearing of their criminal record. In some cases, it may also remove barriers to employment, housing, and other opportunities.
Working with a Criminal Defense Attorney
Because overturning a criminal conviction is complex, it is critical to provide legal advice and guidance tailored to your specific circumstances. An experienced criminal defense lawyer can:
- Identify whether you are eligible for relief.
- Review the court records for appealable errors.
- Prove misconduct or unconstitutional application of the law.
- Prepare persuasive arguments to present before the judge.
For a consultation or case review, contact a criminal defense attorney to discuss your options.
