Which of the following is mandatory for the prosecution in a criminal case?

In a criminal case, the prosecution is required to prove the defendant's guilt beyond a reasonable doubt. This standard is fundamental to the justice system, emphasizing the presumption of innocence that every defendant holds until proven guilty. The burden of proof lies with the prosecution, meaning that it is their responsibility to present sufficient evidence that establishes the defendant’s guilt to a high degree of certainty. This is crucial in protecting the rights of the accused and ensuring that wrongful convictions are minimized.

While notifying the court of pre-trial motions and providing a written statement to the defense may be procedural requirements in some contexts, they do not rise to the level of fundamental obligation that the prosecution has regarding proving guilt. Similarly, the request for a public defender pertains to the rights of the accused rather than a mandatory action of the prosecution.
