Generally speaking, the MDHL is a casual and fun recreational league. Our rules and protocol are listed here (in the links on the left column) just as a primer for the first-time player or for a refresher for the specifics of our league. 

Otherwise, we've been able to refine these points over time and for the most part, we just get together for some good clean fun.

Jan/10	Crease rule is escalated to disallow any foot-in-crease, resulting in clearing of the offensive zone. Goalie selection criteria has been updated to reflect the underdog team having first choice.
Nov/09	Scoring mercy clause is now updated to reflect a 5+ goal differential to trigger a goalie swap option for the losing team.
Oct/06	GMs and captains are empowered to call penalty shots in their estimation; which supersede a usual penalty-time call (if called by another GM/captain for the same incident). The onus is on each player to retrieve their sub fees from GMs within three weeks of the original game, or else forfeit those fees.
Jan/06	All substitutes will be assigned to teams at the GMs discretion (using the MDHL player rating system for reference purposes). Penalties now last THREE minutes each (running time). Hooking infractions will be zero-tolerance (resulting in penalty calls) Captains, assistants, as well as GMs will be granted the authority to call penalties. Captains, assistants, as well as goalies and GMs will be included in controversial goal decisions; goalies will have the final say in disputes.
