Not Unanimous Agreement
The practice is different as to whether a vote can be considered unanimously when some voters abstain. Robert`s regulation does not explicitly define a “unanimous vote,” although an abstention is not counted as a vote, regardless of the voting threshold.  This book could also be negotiated with “unanimous agreement” or “general approval” if no objection is made.  However, the unanimous vote does not necessarily have to be the same as a unanimous vote (see Not the same as the unanimous vote).  In both cases, absent members are not considered. In Westminster parliaments, leaving the house or leaving the Senate is a concept similar to that of unanimous approval. If a member asks for leave to do something different from the rules, a single objection may prevail.   Some rights can only be waived unanimously. For example, in disciplinary proceedings, only one member may require that the vote on the imposition of a sanction be by ballot.
 Unanimously, iron measures do not necessarily mean that they were taken unanimously. This does not necessarily mean that each panel member voted in favour of the proposal.  This may mean that members who feel that it would be pointless to object to a case would simply agree.  As a general rule, at a meeting of an advisory assembly, transactions are carried out according to a formal procedure of voting, debate and voting. However, if there is no objection, action could be taken unanimously.      The unanimous approval procedure is used to expedite activity by removing the need for formal votes on routine issues on which consensus is likely.  The underlying principle is that procedural safeguards can be waived to protect a minority if there is no minority of shooters.  In non-legislative advisory bodies acting under Robert`s internal regulations, unanimous consent is often used to expedite the review of uncontested applications.    Sometimes it is used as a time-saving device, especially at the end of the session.
Sometimes Members do not want a formal vote on this issue or they know that they would lose such a vote and do not feel the need to take the time to do so. Unanimity is often used to approve the protocol.  If no correction has been made to the minutes, they are unanimously approved without formal agreement.  In this particular case of unanimous approval, there can only be opposition to the approval of the minutes if a correction is made.  A meeting was unanimously postponed. If, at the end of a meeting, no one has more to say, the Chair simply declares the meeting postponed without a formal request or formal vote.  On the other hand, a UN Security Council resolution is not considered “unanimous” when a member abstains.  In the European Union, the Treaty of Amsterdam introduced the concept of “constructive abstention”, in which a Member can abstain in a vote that requires unanimity, without blocking the success of the vote.
