The term 'preside over, as a case' can be solved by the four-letter word 'HEAR'. To preside over a case means to oversee or manage it. This is usually done by a judge or magistrate in a court of law. The presiding officer is responsible for ensuring that the proceedings are conducted fairly and according to the law. They also have the authority to make rulings on matters of law and to impose sentences. The presiding officer must also HEAR all evidence presented in the case and make a decision based on the facts.
