What is the burden of proof in criminal cases?
Asked by: Maida Kozey | Last update: February 19, 2026Score: 4.2/5 (75 votes)
In criminal cases, the burden of proof rests entirely on the prosecution, who must prove the defendant's guilt "beyond a reasonable doubt," the highest standard in U.S. law, meaning the evidence must eliminate any reasonable uncertainty about guilt, ensuring the defendant's presumption of innocence. This differs from civil cases, which typically use the lower standard of "preponderance of the evidence" (more likely than not).
What is the burden of proof in a criminal case?
Burden of Proof
The standard of proof in a criminal trial gives the prosecutor a much greater burden than the plaintiff in a civil trial. The defendant must be found guilty “beyond a reasonable doubt,” which means the evidence must be so strong that there is no reasonable doubt that the defendant committed the crime.
Who beats the burden of proof?
In most cases, the burden of proof rests solely on the prosecution, negating the need for a defense of this kind. However, when exceptions arise and the burden of proof has been shifted to the defendant, they are required to establish a defense that bears an "air of reality".
What is a burden of proof in simple terms?

Where is the burden of proof in criminal cases?
In criminal cases, the prosecution has the onus probandi of establishing the guilt of the accused. Ei incumbit probatio non qui negat. He who asserts - not he who denies - must prove. The burden must be discharged by the prosecution on the strength of its own evidence, not on the weakness of that for the defense.

What are the three levels of burden of proof?
The three main burdens (or standards) of proof in law, from lowest to highest, are Preponderance of the Evidence, required for most civil cases (more likely than not); Clear and Convincing Evidence, used in certain civil matters needing higher certainty; and Beyond a Reasonable Doubt, the strict standard for criminal convictions, meaning near-certainty of guilt.
Can screenshots of messages be used as evidence?
Yes, screenshots of messages can be used as evidence, but they are often considered weak or unreliable on their own because they can be easily edited, cropped, or taken out of context, making them difficult to authenticate; courts prefer original messages with complete metadata (dates, times, sender info) and often require extra proof, like testimony or forensic analysis, to confirm they are genuine.
Who must prove the burden of proof?
The burden of proof, sometimes known as the “onus”, is the requirement to satisfy that standard. In criminal cases, the burden of proof is on the prosecution, and the standard required of them is that they prove the case against the defendant “beyond reasonable doubt”.
Can someone be convicted without evidence?
No, you cannot be convicted without evidence, but "evidence" includes much more than just DNA or video; witness testimony, confessions, and circumstantial evidence (like being near the scene) can be enough for a conviction if they prove guilt "beyond a reasonable doubt". A person can be arrested with less evidence (probable cause), but to be convicted, prosecutors must present strong, credible evidence, often relying on witness statements or other forms of indirect proof when physical evidence is lacking.
Who has to show the burden of proof?
Almost always, the burden of proof rests on the prosecution, and the defendant need not prove innocence. Still, there are situations where a defendant may wish to prove their innocence, such as during claims of self-defense and insanity.
Can hearsay be considered as evidence?
California's "hearsay rule," defined under Evidence Code 1200, is a law that states that third-party hearsay cannot be used as evidence in a trial. This rule is based on the principle that hearsay is often unreliable and cannot be cross-examined.
What happens if the burden isn't met?
Here's what happens if the burden isn't met: Plaintiff's Claim: The claim may be dismissed, leaving our client without compensation for injuries. Negligence: Proving the defendant's fault is essential. Without clear evidence of negligence, there is no responsibility for damages.
How much evidence is needed to convict someone of assault?

What is the #1 reason prosecutors choose not to prosecute?
The #1 reason prosecutors choose not to prosecute is insufficient evidence, meaning they can't meet the high legal burden of proving guilt "beyond a reasonable doubt," even if they suspect wrongdoing. Other major factors include lack of resources, victim/witness uncooperativeness, procedural errors, and cases not serving the public interest or justice system's goals.

To charge someone, police need probable cause (a reasonable belief a crime occurred and the person did it), a lower standard than for conviction, which requires proof beyond a reasonable doubt (near certainty of guilt). Charges can start with just a witness statement or officer observation, but for conviction, prosecutors need strong evidence like testimony, forensics, or consistent circumstantial evidence to prove guilt, not just suspicion, to a judge or jury.

Evidence not admissible in court typically includes illegally obtained evidence (violating the Fourth Amendment), hearsay (out-of-court statements used for their truth), irrelevant or speculative information, privileged communications (like psychotherapist-patient), and confessions obtained through coercion, with rules varying slightly by jurisdiction but generally focusing on reliability, legality, and relevance.
Do judges look at text messages?
Texts Must Be Authenticated
Judges look for reliability before allowing texts into a case. Witnesses, forensic experts, or detailed records may be used to establish a connection between a message and the defendant. If those links are weak, the defense has a strong chance to prevent the texts from influencing the jury.
Can deleted WhatsApp messages be used in court?
If the Messages Are Unaltered and Retrievable
WhatsApp's end-to-end encryption makes it difficult to modify messages. However, courts will only accept messages that can be directly retrieved from a device, cloud backup, or forensic extraction tools like Cellebrite.
