What, if Anything, is Wrong with a Copenhagen Commission?

The European Union has two challenges regarding democracy protection: one is the question of how the European Union should respond to the actions of the current Hungarian government. The other challenge is how to devise, for the long term, a new set of institutions or 'mechanisms' to respond to deteriorations of democracy and the rule of law in a member state. Both challenges can be looked at from at least two crucial, but in the end clearly different, perspectives. One is a practical one: what is deemed politically feasible and what is likely to be effective in changing the conduct of a member state government? The other one is more clearly normative: what can be justified from, broadly speaking, a liberal democratic perspective?
