Key legal question
Whether grading of two comparable exam papers by different examiners using different standards violated equal treatment.
Extracted holding
Yes. The grading process was not compatible with equal treatment because the papers were assessed by different examiners without a sufficiently coordinated common benchmark, and the discrepancy could have affected the result.
Extracted reasoning
The court held that exam grading is normally reviewed only for manifest abuse of discretion, but that this limited review requires strict safeguards against unequal treatment. If the task-setter does not correct all papers and no coordinated assessment criteria are established, there is a latent risk of unequal grading. Here, concrete indications showed divergent standards between the examiners.
