How can I present information during oral proceedings?

With the authorisation of the division, you can present information either by sharing your screen or by showing information on paper via the camera. Any items displayed in this way will not be considered to constitute a submitted document. Before the presentation, the division might ask you to submit the information so that it can be included in the minutes and/or distributed to the other parties.

For security reasons, screen sharing and the whiteboard functionality are not active by default in Zoom. They can, however, be activated by the chair at the parties' request and subject to the agreement of the division.
