A trial is a formal legal proceeding presided over by a judge. This will be a judge of the Superior Court, either publicly employed by the State of California or privately hired by the Parties and empowered by a public Superior Court Judge.
The judge will enter a judgment after each side presents its evidence and arguments in accordance with legal standards and procedures. This may include witnesses, expert testimony, and documentary exhibits. This process of hearing a case and rendering a judgment is called "adjudication" of an issue or all issues.
The judge's decision will be binding on all parties. Sometimes, one of many issues is tried and decided if that issue will enable resolution of other issues in the case. The Court's decision on that one issue will be the "rule of the case" and binding on the Parties. The Court's judgment may be appealed if either Party believes that it is the result of error.
