Burden and standard of proof

Can You Answer This?

Practice with real exam questions

Rachel is charged with theft after allegedly taking property from a charity event without authorization. She presents a statutory provision that allows a defendant to argue that they believed the property was abandoned if proven on the balance of probabilities. Rachel provides witnesses stating that the items were found in a designated discard area for several days. The prosecution insists the property remained under the charity’s control. Rachel believes the statutory defense shifts the responsibility to the prosecution to disprove her belief.


Which of the following is the best statement regarding the burden and standard of proof in this scenario?

Overview

The burden and standard of proof are central doctrines in both criminal and civil legal proceedings, defining the obligations of parties to prove or disprove allegations and the level of certainty required to establish facts. The burden of proof determines which party is responsible for proving the elements of a case, while the standard of proof sets the degree of conviction needed to persuade the court of a particular fact or outcome. These concepts play a key role in ensuring fairness and justice within the legal system, influencing the admissibility and evaluation of evidence.

The Burden of Proof: Legal and Evidential

The burden of proof signifies the obligation a party bears to present convincing evidence in court. It is divided into two categories: the legal burden and the evidential burden.

Legal Burden

The legal burden, often referred to as the persuasive burden, denotes the duty to prove a central fact in dispute. Generally:

  • In criminal matters, the prosecution carries this burden.
  • In civil disputes, the claimant bears it.

A landmark case illustrating this principle is Woolmington v DPP [1935] AC 462, where Lord Sankey LC declared:

"Throughout the web of the English Criminal Law one golden thread is always to be seen, that it is the duty of the prosecution to prove the prisoner's guilt..."

However, there are exceptions where the defendant assumes this burden. For instance, in cases involving insanity, the defendant must prove the defense on the balance of probabilities, as recognized in R v Codere (1916) 12 Cr App R 21. Statutory provisions may also impose this burden on defendants, such as section 2 of the Homicide Act 1957, which requires the defendant to establish certain defenses.

Evidential Burden

The evidential burden involves presenting sufficient evidence to raise an issue for the court's consideration. Unlike the legal burden, it can shift between parties during the course of proceedings. Picture it as a scale that tips back and forth as each side introduces evidence to support their claims.

For example, if a defendant raises a self-defense claim, they must initially present evidence to support it. Once this is done, the prosecution must disprove the claim beyond reasonable doubt. This principle was established in R v Lobell [1957] 1 QB 547, where Lord Goddard CJ stated:

"Once evidence of self-defence is raised, it is for the prosecution to negative it."

Standards of Proof

The standard of proof determines the level of certainty required for a court to accept a fact as proven. This standard varies between criminal and civil cases.

Criminal Standard: Beyond Reasonable Doubt

In criminal cases, the prosecution must prove the defendant's guilt "beyond reasonable doubt." This stringent standard reflects the principle that it is better for guilty persons to go free than for an innocent person to be wrongfully convicted. Think of the level of certainty you require before making a life-changing decision, such as purchasing a home; you would need to be almost entirely convinced of your choice, leaving no substantial doubts.

Judges often avoid defining "beyond reasonable doubt" rigidly, but in R v Majid [2009] EWCA Crim 2563, guidance suggested that jurors must be "sure" of the defendant's guilt.

Civil Standard: Balance of Probabilities

In civil cases, the standard of proof is the "balance of probabilities." This means that a fact is considered proven if it is more likely than not to be true—envision tipping the scales just over the 50% mark. This lower threshold reflects the different objectives in civil proceedings, where the focus is on resolving disputes between parties rather than determining criminal guilt.

Reverse Burdens and Human Rights Considerations

Reverse burdens shift the responsibility of proving certain elements from the prosecution to the defendant and raise important legal and ethical questions, especially concerning the presumption of innocence under Article 6(2) of the European Convention on Human Rights (ECHR).

Courts must carefully evaluate whether imposing a reverse burden is justified and proportionate. In R v Lambert [2001] UKHL 37, the House of Lords provided criteria for this assessment:

  1. Justification and Proportionality: The reverse burden must serve a legitimate aim and be necessary in a democratic society.
  2. Fair Balance: There must be a reasonable relationship between the means employed and the aim sought to be achieved.

Courts often interpret statutory provisions as imposing only an evidential burden on the defendant to preserve the presumption of innocence. As Lord Bingham noted in Sheldrake v DPP [2004] UKHL 43:

"The court should not be astute to find that a reverse burden of proof has been imposed unless the language of the statute makes it plain that this was the intention of Parliament."

Practical Application and Case Studies

Case Study 1: Drug Possession with Intent to Supply

Consider Alex, who is charged under section 5(3) of the Misuse of Drugs Act 1971 for possession of cocaine with intent to supply.

  1. Prosecution's Burden: The prosecution must prove that Alex possessed the cocaine and intended to supply it to others.
  2. Defendant's Evidential Burden: If Alex claims the drugs were for personal use, he must present initial evidence supporting this assertion.
  3. Shifting Burden: Once raised, the prosecution must disprove Alex's claim beyond reasonable doubt.

This illustrates how the evidential burden can shift and how the standard of proof applies at each stage.

Case Study 2: Diminished Responsibility in Murder

Riley is on trial for murder but raises the defense of diminished responsibility under the Homicide Act 1957.

  1. Prosecution's Burden: The prosecution must prove the elements of murder beyond reasonable doubt.
  2. Defendant's Legal Burden: Riley must prove diminished responsibility on the balance of probabilities.
  3. Outcome Impact: Successfully establishing this defense reduces the conviction from murder to manslaughter.

This case highlights the defendant's assumption of the legal burden and the differing standards of proof in play.

Conclusion

The complex interplay between reverse burdens and the presumption of innocence presents significant challenges in legal proceedings. Courts meticulously assess whether shifting the burden to the defendant aligns with the rights protected under Article 6(2) of the European Convention on Human Rights, as demonstrated in R v Lambert [2001] UKHL 37. This scrutiny ensures that any deviation from the conventional allocation of burdens is justified and proportionate.

A clear distinction between the legal and evidential burdens is essential. The legal burden determines who must ultimately prove a fact, while the evidential burden involves producing enough evidence to put a matter before the court. The standards of proof—"beyond reasonable doubt" in criminal cases and "balance of probabilities" in civil cases—set the thresholds for how convincingly these facts must be established.

These concepts do not operate in isolation but interact throughout the judicial process. In cases involving defenses like self-defense or diminished responsibility, the initial evidential burden may rest with the defendant, but the prosecution retains the ultimate burden to disprove the defense to the appropriate standard. The case studies of Alex and Riley clarify how the allocation of burdens and standards of proof can significantly influence legal outcomes.

It is imperative for legal professionals to skillfully manage these doctrines. Misapplication can lead to unjust results, undermining public confidence in the legal system. Therefore, a comprehensive understanding of the burden and standard of proof, informed by authoritative case law and statutory provisions, is necessary for the fair and effective administration of justice.
