To dismiss means to officially decide or announce that something, such as a legal case or an allegation, is to be concluded without further consideration or trial. This can happen if the matter is found to be without merit, or if procedural rules dictate a dismissal. In a broader sense, to dismiss can also refer to ending someone's employment, rejecting a proposal, or diminishing the importance of something.
