There was recently two days of debate in the House of Lords concerning the triggering of Article 50 of the Lisbon Treaty, stating the UK's intention to leave the European Union.
The opening statements made it clear that the decision had already been made, that the Lords would not, under any circumstances, overturn the decision to trigger Article 50.
This means that any commentary, arguments, discussions made during these two days (~800 Peers x ~£300 x 2 days; around £720,000 of tax money), were purely symbolic.
As far as I can tell, this undermines the purpose of the Lords, as a balance to the Commons. Where decisions on law and policy can be blocked by a (relatively) impartial group of people.
So, what was the point in these two days of highly publicised discussion? What was it for?
