In exceptional cases where the draft assessment report clearly does not fulfil those requirements the Commission shall agree with the EFSA and the rapporteur Member State on a period for resubmission of an amended report which shall not exceed three months .. This sentence is hard to understand. A simpler version with equivalent meaning is the following:
In exceptional cases , where the draft assessment report clearly does not meet the formal requirements recommended by the Commission , the Commission shall agree with EFSA and the rapporteur Member State on a deadline for resubmitting an updated report . This period may not exceed three months .
