BCS governance is based on a hierarchy of regulations, In respect of Member Groups this is as follows:-

• Charter & Bylaws approved by Privy Council (available at link)
• Member Regulations approved at BCS AGM (available in the Members Secure area at www.bcs.org/member-regulations) 
• BCS Code of Conduct (available in the Members Secure area at www.bcs.org/code-conduct)
• Trustee Board regulations (available in the Members Secure Area at www.bcs.org/tb-regulations)
• Member Group Rules approved by Community Board (these rules)
• Constitutions approved at the Member Group’s AGM. Note these are now optional for all Member Groups. Member Groups may choose not to have a constitution as the Member Group rules approved by Community Board now fulfill all the requirements of a Member Group constitution.

Each level must be compatible with the level above it. In the event of conflict between two documents the higher one takes precedence.
