Decision making

The Las Posas Users Group (LPUG) operates under a charter as a stakeholder group.

The preferred method of decision-making is via group consensus.  In the event of non-consensus or if any participant calls for a vote on a given issue, the issue in question will be placed on a subsequent meeting agenda for consideration by the LPUG Voting Panel. The voting panel will conduct a hearing and vote on motion(s) made by the panel members.
