Can decisions be made without the chairman at a meeting?

Yes, decisions can be made without the chairman at a meeting, provided that the organization's bylaws or rules allow for it. Typically, a designated member or vice-chair may lead the meeting in the chairman's absence. However, the validity of any decisions made may depend on quorum requirements and the specific procedures outlined in the governing documents. It's important for the group to ensure that proper protocols are followed to maintain legitimacy.
