8.2 Email decision declaration
Taught in 8. How a 3GPP meeting decides, and the word it decides in (How standards actually get made, in depth).
Authority for an email decision to take place should usually be agreed at plenary meeting. If this is not possible, there shall be a clear notification (i.e. status report) indicating that there will be an email decision. This notification shall be sent on the main mailing lists indicating the mailing list where the discussion will take place (TSG, WG or SWG list). Target and timeframe shall be clearly indicated. A permanent Chair (i.e. WG Chair or Vice Chair) shall be nominated, who will be responsible for managing the email decision procedure, including initiation, monitoring and announcing when it is complete.
