Hi Wouter, I have been accepted from Groningen but still no news from Leiden. If you had to choose on eof the two, which one would you choose. I am interested in international law of armed conflict and peace.

from those you have mentioned i think i would choose Leiden, although not all courses they offer are equally good. in European Business Law i would also consider Pallas LL.M. don't worry about the application deadlines, an friend of mine applied late and got accepted nevertheless. the program is really good with approx. 60 professors teaching in all 8 subject during the year.

anything you choose in NL, avoid accomodation with Woonstichting De Key by any means necessary!

Law comes in many different flavours, and hence it is hard to compare the different universities. Please be aware that at least 90% of the law degrees are in domestic (dutch) law, which I suppose is not very interesting for internationals.
For international and European law I would consider Utrecht, Leiden and Amsterdam.
Groningen is a decent law faculty, but not for international law.
Leiden is popular among Americans because it is a well known old university.
Amsterdam and Utrecht offer the best teaching; more dynamic and up to date than the Leiden program (some old -but famous- profs there).
If the international moot court (Jessup) results are anything to go by, than pick Amsterdam. They won 4 out of 5 national competitions over the last 5 years.

can i accept a position and later withdraw?
