I also forgot to link to this; but a better summary of early March EU reactions is below:

Hungary throws down gauntlet to EU | European Voice

...Thorbjørn Jagland, the secretary-general of the Council of Europe, has said that some of the amendments introduced today reintroduce legal provisions annulled by the constitutional court.

He said last Wednesday (6 March) that the return of these clauses endangered "the fundamental principle of checks and balances in a democracy".

His declaration prompted José Manuel Barroso, the president of the European Commission, to call and write to Orbán on Friday. The United States also said on Friday that the amendments - now approved - could threaten "the principles of institutional independence".

...No leading EU politician or official has explicitly called for EU to be stripped of its voting rights in the EU's institutions, though Swoboda said that the EU might need "to make use of all measures available".

Four foreign ministers - from Germany, Denmark, Finland and the Netherlands - on Wednesday (7 March) said that the European Union needed a "a new and more effective mechanism to safeguard fundamental values in member states is needed".
