• Lazy 2/3 Majority – Lazy 2/3 majority votes requires at least 3 votes and twice as many +1 votes as -1 votes.
• Vetoes

A valid, binding veto regarding a code commit cannot be overruled. If a veto is cast, it must be accompanied by a valid reason explaining technical explanation giving the reasons for the veto. The technical validity of a veto, if challenged, can be confirmed by anyone who has a binding vote. This does not necessarily signify agreement with the veto - merely that the veto is valid. If you disagree with a valid veto, you must lobby the person casting the veto to withdraw their veto. If a veto is not withdrawn, any action that has already been taken must be reversed in a timely manner.
