What are the main functions of a judge in a courtroom?

The primary role of a judge in a courtroom involves overseeing court proceedings and ensuring that trials are conducted fairly and within the bounds of the law. This function encompasses a variety of responsibilities, including maintaining order in the courtroom, ruling on motions and objections, guiding the jury in their deliberations if present, and making determinations regarding the admissibility of evidence. The judge's impartiality is crucial in upholding the principles of justice and protecting the rights of all parties involved in the legal process.

In contrast to this primary function, a prosecutor represents the government in criminal cases, advocating for the state's interest in securing a conviction. A judge does not serve this role, as it would compromise their impartial position in the court. Similarly, while a defendant may have legal representation, the judge does not advocate for their interests directly; instead, they ensure that the legal process respects the rights of the defendant. Lastly, judges do not provide legal advice to jurors, as jurors are expected to interpret the law and evidence based on their own understanding and the instructions given by the judge. Thus, the judge's role is distinctly centered around maintaining a fair and lawful trial process.
