In the history of the League there have been many variation of the rules for the league. Often changes came about under new circumstances such as increases in archers of a specific classsification, and other times a new BUTTS League Organiser would tweak the existing rules.
The Biggest change in rules came at the end of the 2006/07 Season when the League changes format. The rules were changes under agreement at a BUTTS AGM, and have been unchanges since then.
Below are a selection of the rules that have been enforced within the league throughout the year. I have attempted to put them in chronological order, but having not been there, I cannot guarantee correctness.
