The committee adopted the motion on December 12. On December 14, the department contacted me to ask what the deadline was for section a. Since I hadn't received any instructions from the committee on the matter, I asked the chair, and he decided to make the deadline the same for sections a and b, in other words, use the deadline in section b for section a, as well. I got back to the department the same day with the chair's suggestion.
On February 2nd, 2023. See this statement in context.
