4. Besorgnis der Befangenheit von Mitgliedern der erstinstanzlichen Organe

Catchword:

1. The Guidelines, Part E, Chapter XI, set out the procedure whereby the reasons of a responsible superior's decision rejecting a challenge to the impartiality of a division can be appealed. This procedure does not make the responsible superior's decision formally appealable (Reasons 2.3 and 2.4).

2. The unexplained omission of the reasons of the responsible superior's decision from the final decision of the division justifies the suspicion of partiality and constitutes a substantial procedural violation (Reasons 2.9 and 2.15).

3. The principle of the prohibition of "reformatio in peius" is not applicable where a case is to be remitted to a division in a new composition because of a suspicion of partiality (Reasons 5.5 and 5.6).
