> it is acting as a barrier to democratically arrived at decisions.
No it isn't. The decision was to leave, not how to leave.
A question I might ask is, what difference is the closeness of the victory (52:48) and the size of the turnout (72%) making to the Brexit "decisions" (ha-ha) that are taken? Or would we see the same decisions even if the victory had been 98:2 on a 100% turnout? I think the Lords would kick less back if that had been the outcome.
To me, it seems that that the Lords are trying to get a Brexit that fairly represents the different opinions that exist, rather than see an extreme Brexit forced through by fervent loons like JRM. They are looking for a Brexit that represents all of the people, not just a segment of the victors.
