One way to handle an emergency situation is to have it that the DAO director has to ask Matt to take action.
Before Matt takes action he needs to send an action proposal to the DAO director for aprovel. Once he gets the DAO directors aproval of the action he can act on it.
This would all be documented of coarse. This way at least 2 people are involved.

Just an idea.
This way if Matt thinks action is not needed then he can say so.
