Pair (parliamentary convention)
(重定向自Live pair)
In parliamentary practice, pairing is an informal arrangement between the government and opposition parties whereby a member of a House of Parliament agrees or is designated by the party whip to abstain from voting while a member of the other party needs to be absent from the House due to other commitments, illness, travel problems, etc. A pairing would usually be arranged or approved by the party whips and will usually not apply for critical votes, such as no-confidence votes.
