The applicant's members were employees of the first respondent. On 5 February 2014, the employees were awarded $59,246.85 by an Arbitrator. The award was registered by the High Court on 24 September 2015 under HC5433/15. The second respondent (Sheriff) executed the order but could not collect the full amount, leaving a balance of $8,302.72 outstanding. When the applicant reinstructed the Deputy Sheriff for a second execution, the first respondent filed an urgent chamber application for an interdict on 4 August 2017 (HC 7246/17), which was removed from the roll for lack of urgency on 9 August 2017. The first respondent simultaneously filed an application for rescission of the registration of the arbitral award (HC 7245/16). On 17 August 2017, the first respondent filed another urgent chamber application identical to the 4 August 2017 one under HC 7591/17. The applicant opposed this application but erroneously cited the wrong case number (HC 7246/17 instead of HC 7591/17) on its opposing papers filed on 28 August 2017 and served on 29 August 2017. Due to this wrong case number, the application was heard unopposed on 4 October 2017 and judgment was granted in favor of the first respondent. The applicant filed the present application for rescission of judgment on 17 October 2017 after being informed of the order on 10 October 2017.
