WCA Regulations and Guidelines

Older Versions of the Regulations

Until 2011, the Regulations were maintained by Ron van Bruchem and the WCA Board. Since then, the WCA Regulations Committee is in charge of them.
For the 2013 release, the Regulations were split into two documents: the Regulations and the Guidelines.
Starting with 2013, updates (with lists of changes changes) will be announced on the WRC Announcements page.

Here are older versions of the regulations. None of them are official anymore.
