Parliament needs to get a grip on EU justice and home affairs laws

At a time when MEPs are trying to grasp every possible opportunity to extend their own powers (and give themselves more cash), it’s about time that national parliamentarians showed some assertiveness over EU decision-making – or they risk becoming even more marginalised in EU affairs. The Lisbon Treaty shifted substantial control away from national parliaments to MEPs (hardly credible protectors of democracy in Europe), the Commission and EU judges. As a result, the UK Parliament was weakened (and the Lisbon Treaty’s yellow card procedure did not make up for this, as now is becoming increasingly clear).

But MPs now have a chance to claim some of these powers back.

How? In a new briefing published today, we argue that by a series of simple amendments to the Government's proposed EU 'referendum lock', the UK Parliament could turn itself into one of the most powerful chambers in Europe, insofar as EU policy is concerned. These amendments would require Ministers to seek the approval of Parliament before signing up to any EU laws in justice and home affairs. If the answer is No, the government can’t opt in.

This may seem like a boring detail, but on the contrary – it’s absolutely vital.

For the first time, this would give Parliament, and voters, a real democratic check on the extension of the EU's powers – although it would still fall far short of repairing all the damage caused by the erosion of democracy through successive EU Treaties.

Policing, crime, immigration and asylum are issues are hugely politically sensitive and any decisions to sign up to new EU laws in these areas need to be thoroughly debated and democratically accountable. This should be Parliament's job. As the German Constitutional Court argued in its ruling on the Lisbon Treaty:

Due to the fact that democratic self-determination is affected in an especially sensitive manner by provisions of criminal law and criminal procedure, the corresponding basic powers in the treaties must be interpreted strictly - on no account extensively -, and their use requires particular justification.

As it currently stands, the Government's proposed Bill, although a significant step forward, fails to address the day-to-day transfer of crime, policing and immigration powers from the UK to the EU. So any decision to opt in to a proposal like the controversial European Arrest Warrant will not be covered by the lock.

And the thing is, justice and home affairs is the area in which the EU gains the most new powers under the Lisbon Treaty. The EU now has two Commissioners rather than one, 17 databases and a rapidly expanding budget to fulfil its ambitions here.

Most importantly, European judges will have the final say over any law that the UK Government decides to opt in to. By definition, this is a transfer of powers.

In other words, it's a zero-sum game: every new justice or policing law the Government signs up to gives more power to the EU institutions at the expense of MPs, Parliament and the British courts. This is a big decision, which currently rests solely on Government Ministers' discretion.

The EU's growing ambitions in justice and home affairs deserve Parliament's undivided attention. It is perfectly reasonable for MPs to demand the power to vote on these crucial decisions that the Government makes in the name of their constituents. In fact, it would be a dereliction of duty not to.
