14 judgments interpreting, applying, or limiting the provisions of this Act. Sorted by court tier then reverse-chronologically.
You don't have to prove you didn't know the package contained drugs — you only need to raise the question with some evidence. The prosecution must then prove you did know, beyond reasonable doubt.
Section 28's apparent reverse legal burden on the accused must be read down under s.3 HRA to impose only an evidential burden to be compatible with the presumption of innocence in Article 6(2) ECHR.
Holding. Section 28 reverse-onus is reduced to an evidential burden by HRA s.3 reading.
If undercover police did no more than give you a normal chance to sell drugs — the kind of opportunity any buyer might present — that's fine. But if they pressured or talked you into something you wouldn't otherwise have done, the case can be stopped.
Entrapment by police agents in undercover drug-supply operations may justify a stay under abuse-of-process principles or exclusion under PACE s.78; the touchstone is whether the police did no more than provide an unexceptional opportunity to commit the offence.
Holding. Entrapment in MDA cases triggers abuse-of-process review under the 'unexceptional opportunity' test.
When an officer arrests or searches you, they need their own reasonable basis to suspect you — not just an order from a superior. They can rely on briefings, but there has to be something specific in their head, not blind obedience.
Reasonable suspicion under MDA 1971 search and arrest powers must rest on facts personally known to the constable; the constable need not know all the underlying intelligence but must have a personal evidential basis for his suspicion.
Holding. Reasonable suspicion under stop/search and arrest powers is an objective standard but must be grounded in the constable's own state of mind.
If you hand drugs back to someone — even the person who originally gave them to you for safekeeping — that counts as supplying. It does not matter that you're not selling or that the drugs were never really yours.
'Supply' under s.4 requires a transfer of physical control with the intention of conferring the benefit of the drug; merely holding drugs to return to their owner amounts to supply because it furthers the recipient's purpose.
Holding. Returning drugs to their lawful or unlawful owner constitutes 'supply' under s.4 MDA 1971.
Even a tiny trace of a drug — a few grains, a scraping — is enough for possession. There's no minimum amount you need to be carrying. If it can be measured, the prosecution can charge you.
Any measurable quantity of a controlled drug, however small, is capable of constituting possession under s.5; there is no de minimis exemption — the question of usable quantity goes to evidence and not to elements of the offence.
Holding. Section 5 has no de minimis rule; any measurable quantity suffices for possession.
You can't be done for possessing drugs you didn't know you had. If someone slips something into your bag without your knowledge, that isn't possession — the law requires you to be aware you're holding something.
Possession under the predecessor Drugs (Prevention of Misuse) Act 1964 — and now under s.5 MDA 1971 — requires both physical custody and knowledge of the existence of the thing possessed; mere accidental or unwitting custody does not amount to possession in law.
Holding. Possession is a knowing-custody concept; ignorance of the existence of the thing held excludes liability.
Once you put forward enough evidence that you didn't know or suspect the substance was a controlled drug, it's down to the prosecution to disprove your account beyond reasonable doubt. They have to dismantle your defence, not the other way round.
Once the defendant raises sufficient evidence under s.28(3) that he did not know nor have reason to suspect the substance was a controlled drug, the prosecution bears the legal burden of disproving that defence beyond reasonable doubt.
Holding. Post-Lambert, s.28 operates as an evidential burden on the defendant with the legal burden of disproof on the Crown.
Dealing near schools or using children to run drugs isn't a separate crime — it pushes your sentence up within the normal guidelines for supply. Expect a heavier punishment, but you're still being sentenced for the underlying supply offence.
Section 4A's aggravating factors (supply near schools, use of a child courier) must be considered as part of sentence aggravation rather than an independent offence; the court applied the Sentencing Council guideline framework calibrated for s.4A.
Holding. Section 4A aggravation operates within standard sentencing-guideline framework; it raises but does not create separate offence.
You can't argue you imported or held cannabis because you needed it for pain relief. Parliament has decided which drugs are banned and there's no medical-need loophole — even genuine self-treatment won't save you.
Necessity is not a free-standing defence to importation or possession of cannabis for self-medication; Parliament's prohibition under s.3 (and s.5) reflects a settled policy choice that the common-law necessity defence does not displace.
Holding. Medical necessity is not a defence to MDA 1971 offences; the statutory regime is exhaustive.
If you run or own premises, you only commit this offence if you actually knew controlled drugs — not just any drugs — were being used there. Vaguely suspecting people were getting high isn't enough to convict you.
Section 8(d) liability for permitting drug use on premises requires the occupier or manager to know that a controlled drug specifically is being used; awareness that drugs of some sort are being consumed is insufficient — the prosecution must prove knowledge of a controlled-drug character.
Holding. Section 8 mens rea requires actual knowledge that a controlled drug is being used on the premises.
Police need a genuine, reasonable suspicion before stopping and searching you for drugs. If they search you unlawfully, what they find isn't automatically thrown out — but the trial judge can refuse to let the prosecution use it if admitting it would be unfair.
Section 23 stop-and-search powers must be exercised on reasonable suspicion as understood in the post-PACE jurisprudence; an unlawful search may render evidence subject to s.78 PACE exclusion analysis but does not automatically vitiate the seizure.
Holding. Section 23 incorporates the reasonable-suspicion standard and is supervised through PACE s.78 admissibility.
Saying you'll sell drugs is itself the offence — you don't actually have to have any drugs, or any real intention to deliver. The moment the offer is made, you're guilty, even if it was a bluff.
An 'offer to supply' under s.4(3)(b) is constituted by the words or conduct alone; the actual capacity or intention to deliver the drugs is irrelevant — the offer itself completes the offence.
Holding. An offer to supply under s.4(3)(b) is complete on communication, regardless of capability to perform.
If you knowingly carry a sealed bag or package with something in it, and it turns out to contain drugs, you'll need to point to actual evidence that you thought it was something else. Just saying you didn't know won't cut it.
Once the prosecution proves the accused knowingly had custody of a container with something in it, the burden shifts to the accused to bring himself within s.28 by raising a reasonable belief defence about the nature of the contents; mere assertion of ignorance is insufficient.
Holding. Knowing custody of a container shifts the evidential burden under s.28 to the defendant for the contents' identity.
Whether you meant to deal rather than just use is for the jury to decide based on everything around you — how much you had, the way it was packaged, scales, cash, text messages. No single thing decides it; the whole picture does.
Intent to supply under s.5(3) is a question of fact for the jury; quantity, packaging, paraphernalia, money and lifestyle all bear on inference but no single factor is determinative.
Holding. Intent to supply under s.5(3) is inferred from the totality of evidence including quantity and trappings of dealing.
