Expulsion, also known as ejection, refers to the act of forcibly removing someone or something from a place or situation. This can occur in various contexts, such as in schools, where a student may be expelled for violating rules, or in sports, where a player may be ejected for unsportsmanlike conduct. The process typically involves a formal procedure to ensure fairness. In legal terms, expulsion can also refer to the removal of a person from a country or territory, often due to immigration violations. This action is usually carried out by government authorities and may involve a hearing or review process to determine the validity of the expulsion.
