Block: A block always prevents a proposal from continuing. He expressed an objection in principle. It`s not „I don`t really like it“ or „I liked the other idea better.“ Some groups say that the block means, „I have to leave the group if that`s the case.“ The group can either start working on a new proposal or look for amendments to overcome the objection. In cases where the blockage is due to a fundamental disagreement with the group`s goals, it might be more appropriate for the person to leave. Critics of consensus blocking often find that while the option is potentially effective for small groups of motivated or trained people with a sufficiently high degree of affinity, it had a number of possible shortcomings, particularly the Polish-Lithuanian Commonwealth of 1569-1795, using consensual decisions in the form of liberum veto („free veto“) in its sejms (legislative assemblies). The liberum veto was a kind of unanimous agreement and originally allowed any member of a Sejm to veto a single law by calling Sisto activitatem! (Latin: „I stop!“) Or never pozwalam! (In Polish: „I don`t allow!“).  Over time, it became a much more extreme form, where each member of Sejm could, unilaterally and immediately, force the end of the current session and repeal all previously passed laws of that session. Differences of opinion can support a group`s decision, because with a wide range of information and opinions, there is a greater chance that the group will find good solutions. An easy-to-reach consensus can mask the fact that some people don`t feel safe or confident enough to express their differences. Test the approval by clearly stating the final proposal and asking people to report whether they agree or disagree.
This phase is important to check if there are concerns that have not been heard. If you don`t have consensus, go back to an appropriate earlier stage of the process. For example, note the steps you will take to make a decision. Remind people at the beginning of each meeting and make available expressions of the consensus process and the agenda. One belief used to justify voting is that if a majority of people think something, they must be right. This is not always the case! People rally to a proposal for all sorts of reasons – personal interests, lack of self-confidence to swim against the current, lack of information, or simply haven`t thought much about a topic. . .
