This is the official 2011/2012 Charter.
(Last Updated Dec. 17, 2011)
Note (Dec. 17): added rule 51b to clarify rule on keeper contracts and waivers:
Players who are dropped as a result of a waiver transaction retain their contract status if they are acquired (by any team) during the same season. The player’s contract expires if he remain a free-agent entering the off-season.
