How current is this code group?

Code groups are maintained in the Ichi platform and this page reflects that library directly. New books, editions and amendments are added on an ongoing basis, and jurisdictions can be added on request.

Can I read the full code text here?

This page lists coverage — which books, which edition, which amendments. The code text itself lives inside Ichi, where it's delivered under our licensing agreements with the ICC and other publishers, and where every answer links to the exact section it came from.
