Termination of constitutional complaint after *ex officio* resumption and reissuance of gambling tax assessments; non-applicability of Section 88 VerfGG to waiver-based termination.

The Constitutional Court dismissed the constitutional complaint and ordered the proceedings terminated without the allocation of procedural costs, as the complaining party waived its action following the annulment of the challenged decisions. The dispute concerned tax assessments on gambling machine operations, where the original administrative order had been revoked via *ex officio* resumption of proceedings due to a late-registered machine, prompting the authority to reissue the decision with identical content but including the additional machine. The termination was based on the principle that a waiver renders the subject matter moot (*Klaglosstellung*), and no costs were awarded because the situation did not qualify as a formal waiver under Section 88 of the Constitutional Complainant Act, allowing for a decision without further public hearing under Section 19(3)(3) of the same Act.
