Expulsion means removal of their membership and all rights. Think of membership like a bucket, in that bucket you currently have:
- Access to the space
- Access to online resources
- Use of tools
- Voting rights
- Rights to inspect the books
- Right to inspect the property (blah blah reasonable time, etc)
Only the last 3 items are specifically listed in the Bylaws as rights of membership. Expulsion is taking away the bucket. Suspension or temporary banning (as per the code of conduct) is removing some of the items (access to the space/tools) from the bucket.
If you still feel that the Bylaws need to be changed so that quick action can be taken, please come up with a proposal.
