I prepared a simple PDF table with all of the official languages so that you don’t have to look up the National Law every time. I also added useful notes regarding the EU languages you can use for the request for Unitary effect.
The most special cases are probably Belgium (Dutch, German, French) and Finland (Finnish, Sweden) from the 40 countries.
