Major rule changes.  Leagues must have unanymous consent to change a major rule once a league has started.  A reasonable window must be allowed to vote on a rule (at least 5 days).  Any person that doesn't agree with the change can effectively veto the rule.

Minor rule changes.  2/3 of owners who vote on the rule must approve it, rounded to the nearest number.  So if 9 owners actually vote, 6 would have to approve.  If 7 owners vote, 5 would have to approve.

Very Minor rule changes. 1/2 of owners who vote on the rule must approve it, rounded to the nearest number.  So if 7 owners vote, 4 must approve.
 
If a rule change isn't listed here, it is to be considered a major rule change.  You can submit a rule change to us under the Private League forum if you want it to be considered minor instead of major.  The private League committee will determine whether it is major or minor.

If a decision on a rule is required, then a commish ruling will suffice.  For example, when the new Amateur Draft was added, all leagues needed to set which day the draft lists would become available.  Since not picking a day wasn't an option, the commishes submitted the dates to me - most solicited feedback or did votes in their leagues.
