Question juridique clé
Whether refusal to order a medical analytical expert report violated the appellant's procedural rights.
Solution extraite
No. Statistical comparison remains admissible, and the appellant did not concretely substantiate exceptional practice specificities requiring a different method.
Motifs extraits
The court held that statistical proof is an accepted, rebuttable method for detecting overbilling. The doctor had been invited several times to explain the higher costs but offered only general assertions without concrete supporting evidence.
