Yes, I did include an article in my testimony that I published this week on this question. The Venice Commission of the Council of Europe has condemned the draft law. The Ukrainians asked the Venice commission themselves to comment on their draft law.
One of the major criticisms has been not only that they're going to increase the threshold to 5%, but also that the draft law was drafted by the president. The EU ambassador to Ukraine said that there is no European country where election laws are drafted by presidents. This just doesn't happen in a democratic country. Election laws are drafted by parliaments.
Also, the draft election law was not drafted with discussions with opposition parties. Opposition parties and civil society--and in effect, the west--have been ignored in the drafting of its election law. The aim of the law is to create a large majority in their favour.
