Informative guide explaining what happens when a drug offence charge is incorrectly filed in England and Wales. Covers how drug charges are reviewed and discontinued, legal rights, potential reinstatement, the role of the CPS and practical implications of wrongful charges.

A drug offence charge can arise under the Misuse of Drugs Act 1971 and related legislation when a person is alleged to have committed an act such as possession, possession with intent to supply, importation or production of a controlled drug. In England and Wales, drug offences range from minor possession to serious supply‑related charges, and each carries potential criminal penalties including fines and imprisonment. Prosecutors must ensure that the charge accurately reflects the alleged conduct and that there is credible evidence and proper legal basis before pursuing a case.
Occasionally, a drug offence charge may be incorrectly filed, meaning that the state's decision to charge was flawed due to weak evidence, misidentification, procedural errors, or misunderstandings about how the law applies. This article explains how such situations can be addressed, what rights are involved, and what practical outcomes might occur.
How Drug Charges Are Approved in England and Wales
Before a charge proceeds to court, it is typically reviewed by the Crown Prosecution Service (CPS). Prosecutors apply the Full Code Test, which requires:
- A realistic prospect of conviction based on the available evidence; and
- That it is in the public interest for the case to proceed.
This ongoing review obligation means that prosecutors must reassess their decision if new information arises, evidence weakens or legal issues emerge. If these tests are not met, charges should not be pursued.
When a Drug Charge May Be Considered Incorrect
A drug offence charge may be deemed incorrect or unsound for several reasons:
- Insufficient or unreliable evidence: For example, if forensic testing is inadequate or police fail to demonstrate that the substance in question is a controlled drug.
- Procedural errors in investigation: Where key evidence was obtained unlawfully - such as through an illegal search or breach of proper arrest procedures - this can undermine the prosecution's case.
- Misidentification or misunderstanding of facts: Errors in the initial police investigation, such as incorrect assumptions about possession or intent, can lead to inappropriate charging.
- Incorrect application of the law: Charges must reflect the precise legal offence; mislabelling conduct under the wrong statutory provision may render the charge unsound.
What Happens When the Prosecution Decides the Charge Is Unsound
Discontinuance Before Trial
If, at any point before trial, the CPS determines that the evidence no longer supports the drug charge or that prosecution is not appropriate, it may discontinue proceedings. This is a formal legal step under the Prosecution of Offences Act 1985 and effectively ends the current prosecution in relation to that charge. Discontinuance can occur even if the case has been filed at court, so long as the prosecution has not completed presenting its evidence.
When a case is discontinued:
- The defendant generally does not go to trial; and
- If in custody, they will normally be released without a court hearing.
However, a discontinuance is not necessarily a final bar to future prosecution in all circumstances. If new evidence emerges that meets the prosecutorial standards, the CPS may decide to re‑institute proceedings - though decisions to do so are subject to internal guidance and oversight.
Offer of No Evidence or Formal Acquittal
If charges proceed to court but the CPS finds it cannot support the allegations, it may make an offer of no evidence. If the court accepts this, the matter is treated effectively as a not‑guilty finding on that charge. This is a stronger form of closure than simple discontinuance and normally bars the same charge from being retried unless compelling new evidence arises.
Legal Rights and Protections
Right to Representation
Anyone accused of a drug offence has the right to legal representation. A solicitor can challenge weaknesses in the evidence, procedural mistakes or misapplication of the law, potentially leading to early resolution or discontinuance.
Right to a Fair and Lawful Process
Courts in England and Wales are tasked with ensuring that prosecutions are fair. If continuing a prosecution would be unjust - for example due to significant procedural violations - the court may refuse to allow it to proceed or may stay the proceedings on grounds of abuse of process.
Victims' Right to Review
If a charge is dropped or a decision is made not to prosecute and a complainant (victim) feels this was wrong, the Victims' Right to Review (VRR) scheme allows them to request a second look at the decision within certain time limits (generally within three months of the original decision). This review is conducted independently of the original decision‑maker.
Practical Implications of an Incorrect Charge
Impact on Records
Even if a drug charge is discontinued, arrest and charge details may remain on criminal records unless steps are taken to address them. Inaccurate records can affect employment background checks, travel and reputation.
Possibility of Re‑charge
If a prosecution is discontinued due to insufficient evidence but later new evidence becomes available, the CPS may consider reinstating the charge. This possibility means that discontinuance or withdrawal before trial does not always guarantee that no further action will follow.
Acquittal Protections
If a charge reaches trial and concludes with a formal not‑guilty verdict after an offer of no evidence or acquittal, protections against double jeopardy generally prevent the same charge being brought again for the same facts, except in very limited circumstances.
Common Questions
Can a drug charge be reinstated once dropped?
Yes. If charges are discontinued before trial and new evidence emerges that meets prosecutorial standards, the CPS can re‑institute proceedings subject to guidance and oversight.
Does dropping a charge remove all records?
Not automatically. Police and prosecutor records may continue to exist and may need to be addressed separately through record review or correction procedures.
What if I disagree with the decision not to prosecute?
Under the Victims' Right to Review scheme, victims of crime can request the decision to be reviewed within statutory time limits.
Key Takeaways
An incorrectly filed drug offence charge in England and Wales can arise from evidential weaknesses, procedural errors or legal missteps. The CPS has mechanisms to discontinue prosecutions where charges no longer meet legal standards and to offer no evidence, resulting in effective closure of the case. Individuals have rights, including representation and protections against unfair proceedings, and complainants may use the Victims' Right to Review process if they disagree with decisions not to charge or to discontinue. While discontinuance ends the current prosecution, in some circumstances the CPS can reinstate charges if new evidence or compelling reasons emerge. Understanding these processes helps clarify what to expect when a drug charge is challenged or found to be unsound.
