Branches are also responsible for vetting and approving, deferring or rejecting new party members (a power State Council also has) and are generally responsible for local membership engagement; though branches don't have the power to suspend or expel members. A member residing within a branch catchment area is generally registered to that branch, while a member residing outside of any branch catchment area is considered "at-large", unless a member asks to be moved into another branch. Though members can be involved in more than one branch at a time, they can only be registered as members, and thus have voting power, within a single branch.
