21. (1) Where a safety order, barring order, interim barring order, emergency barring order or protection order has been made, any of the following persons may apply to the court that made the order to have the order discharged:

(i) the Agency,

(ii) the person referred to in subsection (1)(c) of that section, or

(ii) the applicant for that order, or

(iii) the respondent to that application;

(c) in any other case—

(i) the applicant for the order, or

(ii) the respondent to the application for the order.

(2) The court shall, on an application under subsection (1), discharge the order if it is of the opinion that the safety and welfare of the applicant or the dependent person for whose protection the order was made does not require that the order should continue in force.

(a) a matrimonial cause or matter,
