In the event of an attack the quorum requirement for the legislature is a majority of the members of each house who convene for the session. If the affirmative vote of a specified proportion of members of the legislature would otherwise be required to approve a bill, resolution, or for any other action, the same proportion of the members of each house convening at the session is sufficient.
