The Law Lords decision that the British Government must seek the approval of Parliament before acting to trigger Article 50 (proving for exit from the EU) is interesting and provides a precedent that could well impact on all Parliaments wedded to the Westminster system of Government.
On balance I think the decision is to be applauded as it confirms the primacy of Parliament. That is fundamental to our system of democracy.
As far as the UK is concerned and I'm not sure too much will change. The European Union (Notification of Withdrawal) Bill was presented to Parliament yesterday when it had its First Reading. In the 650 member House there is a small bloc of 64 members (54 Scottish National Party, 9 Liberal Democrats and 1 Green) committed to opposing withdrawal tooth and nail. I suspect they will be joined by a rump of Europhile MPs from both the Conservative and Labour Parties who will cross the floor to vote against the Bill. It is perhaps instructive that Jeremy Corbyn has said that Labour respects the Referendum result and will not vote against the Bill. Whether that means he will go so far as to impose a three-line Whip is moot. Whatever, the Bill will pass into Law.
The decision has potential ramifications for New Zealand. Here the Conservatives and, to a lessor extent, Winston First have campaigned for the introduction of binding Citizen's Referenda. The Law Lords decision effectively challenges the legality of that and while their decision does not bind New Zealand it provides a basis for challenge were this country to proceed down that pathway.
I am against binding referenda. Not against CIR per se and Parliament should not disregard lightly the result from a CIR where there is a high turnout and where the decision is clear-cut. But in the final analysis I support the primacy of Parliament to make (hopefully) informed decisions. I think the Law Lords have done democracy a favour.
Updated 11.25 ... It is confirmed that Corbyn has imposed a three-line Whip on his own MPs which has led to the resignation of Tulip Siddiq, one of his shadow ministers.
Updated #2 ... Another shadow minister has quit. This time Jo Stevens, Shadow Welsh Secretary. UK Labour is in a mess.
