Thank you for that.
I'm just wondering what the normal process is and how long we should wait before we take further steps.
I think this study is very important, and those witnesses are required for us to do the work we need to do. I'm just looking for advice on whether the next step is to send a letter to summon them or to wait another couple of days. I don't think we need to wait a significantly long time. We have sent a couple of invitations now and a specific invitation, and it feels like we're not getting a response. That concerns me.
I'd love to hear from the rest of the committee.
