Judges and hearing officers typically do the following:

• Research legal issues
• Read and evaluate information from documents, such as motions, claim applications, and records
• Preside over hearings and listen to and read arguments by opposing parties
• Determine if the information presented supports the charge, claim, or dispute
• Decide if the procedure is being conducted according to the rules and law
• Apply laws or precedents to reach judgments and to resolve disputes between parties
• Write opinions, decisions, and instructions regarding cases, claims, and disputes

Judges commonly preside over trials and hearings of cases regarding nearly every aspect of society, from individual traffic offenses to issues concerning the rights of large corporations. Judges listen to arguments and determine if the evidence presented deserves a trial. In criminal cases, judges may decide that people charged with crimes should be held in jail until the trial, or they may set conditions for their release. They also approve search warrants and arrest warrants.

Judges interpret the law to determine how a trial will proceed, which is particularly important when unusual circumstances arise for which standard procedures have not been established. They ensure that hearings and trials are conducted fairly and that the legal rights of all involved parties are protected.

In trials in which juries are selected to decide the case, judges instruct jurors on applicable laws and direct them to consider the facts from the evidence. For other trials, judges decide the case. A judge who determines guilt in criminal cases may impose a sentence or penalty on the guilty party. In civil cases, the judge may award relief, such as compensation for damages, to the parties who win lawsuits.

Judges use various forms of technology, such as electronic databases and software, to manage cases and to prepare for trials. In some cases, a judge may manage the court's administrative and clerical staff.

The following are examples of types of judges and hearing officers:

Judges, magistrate judges, and magistrates preside over trials and hearings. They typically work in local, state, and federal courts.

In local and state court systems, they have a variety of titles, such as municipal court judge, county court judge, and justice of the peace. Traffic violations, misdemeanors, small-claims cases, and pretrial hearings make up the bulk of these judges' work.

In federal and state court systems, district court judges and general trial court judges have authority over any case in their system. Appellate court judges rule on a small number of cases, by reviewing decisions of the lower courts and lawyers' written and oral arguments.

Administrative law judges, adjudicators, and hearing officers usually work for local, state, and federal government agencies. They decide many issues, such as whether a person is eligible for workers' compensation benefits or whether employment discrimination occurred.
