Is it really possible to inscribe site without waiting on session itself? Never heard about such cases before.
They will bring it forward as an emergency nomination (see article 161 & 162 of the Operational Guidelines
). But that means it still will follow the same process (AB evaluation, WHC vote, at the same session as the other sites), just quicker. We may need to write it down for 2023 (or even 2022).
See this connection
for sites that followed the same route (Ashur, Bam, Battir, Bethlehem, Hebron, Minaret of Jam).
