Key legal question
Whether the doctor could rely on special features of his practice and patient clientele to justify a higher tolerated cost average under the statistical method.
Extracted holding
The factual findings were incomplete and partly manifestly inaccurate; the case had to be remanded for further evidence on possible special features of the clientele and practice.
Extracted reasoning
The tribunal compared the doctor with a different reference group than the applicable general-practitioner group and did not adequately address evidence about diabetic, chronically ill, and foreign patients, which may justify an additional margin.
