The CTF playing rules amendments approval by the Board of Directors and the Delegates at the Annual General Meeting have been included in the CTF Playing Rules.  The National Bylaws are included with the playing rules for easy access.

Each league receives two rule books.  Additional books are available in limited quantities for $3.00 per book.
