The order of mandamus is a form of order issued by a superior court to a lower court, tribunal, public authority or corporation, or to an individual directing them to perform a particular function or duty that they are obligated to perform. This order is issued when there is a failure to perform a legal duty or to correct an abuse of discretion. In summary, the order of mandamus is a judicial command or writ issued by a court of competent jurisdiction ordering an individual or a public authority to carry out a particular action.
