The Judiciary’s video conferencing facilities for remote hearings for civil business:

1. Parties who wish to participate in remote hearings have to be equipped with the following items:

(a) video conferencing (“VC”) unit;
(b) laptop computer;
(c) display unit;
(d) camera;
(e) speaker system; and
(f) microphone.

(I) Availability of Hardware and Software Options

2. To provide more user-friendly and facilitating means of connecting to the court’s video-conferencing facilities (“VCF”), the Judiciary will from 15 June 2020 onward support the use of two alternatives in terms of VC units required of court users for such connection:

(a) hardware option; and
(b) software option.
