Secondly, and politically more interesting, the change gives vastly more power to big countries, especially Germany, because of the ‘65% of population’ criterion. Germany’s 81 million people means its weight in the Council almost doubles, from 8.2% to 15.9%. The weight of Italy, France and the UK also increases from 8.2% to 12-13%. As of now, the ‘big four’ countries together will have 54% instead of 33% of votes. The ‘new 13’ member states that acceded since 2004 also had a third of votes up to now, but see that shrink on 1 November to only a fifth – 21%.

In an attempt to balance things a bit for the smaller member states, the majority required in terms of number of countries increases from ‘over 50%’ to ‘over 55%’. But since in practice this only means approval by 16 instead of 15 member states it is hardly significant.

It is all quite dramatic. The 13 ‘new entrants’ were on par with the old ‘big 4’ but will now be dwarfed by them. The 22 smallest member states had 52% of the vote, but now have only 30% left.

And what about blocking minorities? They will now require at least four member states representing over 35% of the population, preventing a situation where just three big member states could block resolutions.

For example, the four countries of the ‘Visegrad group ‘ (Poland, Czech Republic, Hungary and Slovakia) had almost two-thirds of a blocking minority (58 of 92 required Council votes), but now they are down to a bit over a third (64 of 179 million people). They will find it more difficult to block or water down energy and climate bills.

To complicate things, after heavy lobbying by Poland in 2007, a requirement was introduced (the so-called ‘Ioannina II’ mechanism) that gives member states with ‘55% of 35%’ (or only 19.2%!) of the EU population the power to suspend negotiations to find a compromise. This can be overruled again by simple majority. It remains to be seen how often this clause will be used; ‘Ioannina I’, a similar arrangement, was invoked only once, in a case on sardines. But it will again put a lot of power in the hands of big member states.

Amazingly enough, smaller member states can from now on wield more influence through the European Parliament than through Council. As said, the 22 smaller member states have only 30% of votes in Council, but they have 44% of seats in the Parliament – historically the institution with most the most proportional representation.

What’s the takeaway from all this?

That Council will dominate more than ever before, because it can both agree and block more easily than before. And crucially, that in Council the big boys – and especially Germany – now really rule the roost. Arguably the new rules go too far; there is hardly anything left to protect small member states from the big ones. They need to be very careful in today’s jittery context not to abuse that power.
