Chair Can Veto
When enabled, the chair's rejection immediately rejects the change, regardless of other votes.
Important Notes
- Veto only applies to rejection, Chair approval does NOT automatically approve the change
- Chair's approval counts as a normal vote toward the threshold
- Veto is checked first, before any other approval logic
Use Cases.
- Emergency stop capability for risky changes
- Final authority for compliance-sensitive decisions
- Governance requirement for executive oversight
Chair Breaks Ties
When enabled, the chair's vote decides the outcome when votes are evenly split.
Conditions for Tie-Breaking
- All votes must be cast (no pending votes)
- Approved count equals rejected count
- Chair has voted
Combining Chair Powers
Both powers can be enabled together:
| Setting | Effect |
| Veto Only | Chair can block, but can't force approval |
| Tie-break only | Chair decides ties, but can't override majority |
| Both enabled | Chair has full decision authority |
| Neither | Chair votes like any other member |
Processing Order
When both are enabled, the system checks in this order:
- Veto check - Did chair reject? → Immediately rejected
- Normal threshold - Did approvals meet requirement? → Approved/Rejected
- Tie-break - Is it a tie with all votes in? → Chair decides
Configuration
When creating a VCAB group options can be selected under the Decision Rules section.
The CAB Member can be assigned chair position once selected in the CAB members section.
