The MCC has been the custodian of the Laws of Cricket since the Club's formation in 1787. For a copy of the current version of the laws, please visit the Lords' website
While The Laws of Cricket provide the core rules for a game of cricket, almost every match played around the world has competition specific Playing Conditions which provide amendments to the laws to suit a particular match.
For example, The Laws of Cricket are the same for Test and Twenty20 matches, however the Playing Conditions allow us to play the different match formats.
Almost every cricket association has their own Playing Conditions/Regulations, please see below for some of the Playing Conditions used in elite cricket.
For all Test, ODI and T20 International Playing Conditions, please follow the below link to the International Cricket Council website.
Playing Conditions for Weet-Bix Sheffield Shield, KFC Big Bash, WNCL and all the other major domestic competitions can be found at the law and policies on the Cricket Australia Website
