Supplementary allowance for higher-valued office: calculation of the 18-month waiting period based on concrete-functional duties versus abstract-functional classification

The Federal Administrative Court (BVerwG) granted the plaintiff's application for leave to appeal by admitting the revision proceeding, leaving the lower court's decision pending until the substantive review is complete. The dispute concerns whether the 18-month waiting period required to claim a "supplementary allowance" for performing a higher-valued position under § 46 Abs. 1 of the Federal Pay Scale Act (BBesG) is calculated based on the concrete-functional characteristics of the specific duty post occupied, or on the abstract-functional classification of the office. The admission rests on the case's fundamental legal significance, as the court must clarify the precise interpretation of the statutory waiting period provision to determine if the plaintiff is entitled to the contested allowance.
