It is a very diverse list, with the Tory MPs involved ranging from the wettest of the wets for the driest of the dry and it would appear likely that the MPs who killed the measure did so for a whole range of very different reasons. What is indisputable is that this decision has come back to haunt those 2012 rebels who are ardent supporters of Brexit.
A much larger number of peers, who would deny that they are trying to frustrate the will of the electorate, have passed amendments to the EU reform bill which seek to put constraints on the ability of the government to negotiate which are presented as giving more power over the process of negotiating Britain's exit from the EU to the House of Commons.
Some of the proposals put forward in the Lords were quite clearly wrecking amendments designed to block the implementation of the referendum result, although the worst of these were not passed.
I have my concerns that some of the amendments which have been passed could go horribly wrong. The Brexiteers are convinced that all the amendments are sabotage.
Those ministers and supporters of Brexit who backed David Cameron in 2012, such as Dr Liam Fox, can without hypocrisy criticise the "unelected" Lords for passing amendments which he thinks are likely to make a successful Brexit more difficult, because Liam Fox isn't one of the people who stopped the unelected Lords from being replaced by an elected second chamber.
Some of those who did, however, are among those who have been complaining about the "unelected" Lords this week. It all rather brings to mind the saying "Be careful what you wish for. You may get it."
