Final answer:
In criminal law, the burden of proof lies with the state and they must prove the defendant's guilt beyond a reasonable doubt.
Step-by-step explanation:
In criminal law, the burden of proof is the responsibility of the state to prove the defendant's guilt beyond a reasonable doubt. This means that the evidence presented in the case must leave no reasonable doubt in the minds of the jury that the defendant committed the crime they are accused of. This is a higher standard of proof than in civil cases, where the plaintiff only needs to prove their case beyond a preponderance of the evidence.
