The most significant threat to Parliament being able to function would be MPs being away from Wellington for whatever reason in large numbers. Usually, a maximum of 25 percent of MPs from any one party can be away from the parliamentary precinct at any given time without affecting the proportionality of the votes cast in the House. Proposal number 4 gives the Business Committee the power to adjust or even remove the 25 percent limit. This would allow the House to continue to function with lower numbers of members and to maintain the balance of proportionality created at the last election.
