You can file a complaint with the Danish Agency for Higher Education and Science, if the complaint concerns legal matters related to your decision. The deadline for submitting a complaint is 2 weeks from the day the decision is informed.
This means that you can complain, if you believe the decision violates applicable laws, such as the Public Administration Act, the Act on Gender Equality, and general principles of administrative law. You cannot complain about academic assessments and specific judgements.
If you still believe the decision violates applicable laws, you must send your complaint to VIA University College at apply@via.dk, no later than 2 weeks after the decision is informed. If the case is not reopened, VIA will forward the entire case to the Danish Agency for Higher Education and Science.
