Can I say "sue" instead of "charge" in this context?
Answer from a Native speaker
These two things are different as the act of "suing" and "charging" someone takes place in different courts. When someone is "charged," it means they have been judged as being guilty in a criminal court, by the government (country). This can involve crimes such as fraud, assault, murder, and so on. When a private citizen wants to take someone to court for a criminal act, that is called "pressing charges." Ex: The accused was charged with manslaughter. Ex: The victim pressed charges against his attacker. The act of suing someone happens in civil court, between two private citizens. For example, it might be that someone damaged another person's property. Thus, the victim can sue the other party in civil court. Ex: The man sued his former boss for unpaid wages. Ex: The celebrity sued the newspaper for spreading false rumors.
