Here you can find a recent article (in Swedish) in Universitetsläraren about a scholarship student case at Chalmers. The student was entitled to a top-up payment from the department to reach similar pay as employed doctoral students (the regulations can be found on DS web page). Unfortunately he did not receive this during his time at Chalmers, but after a great job done by our DOMB and a labor union representative, he was able to receive the money retroactively.
