Kernrechtsfrage
Whether the judgment 2C_455/2013 was unclear, incomplete or contradictory so as to justify clarification under Art. 129 BGG.
Extrahierter Entscheid
The request was admissible only to the extent it sought clarification of the operative part, but it could not be used to obtain a substantive reconsideration or supplementation of the merits; the request was therefore rejected insofar as entered into.
Extrahierte Begründung
Clarification under Art. 129 BGG serves only to make the true meaning of the decision clear, not to change it or reopen a finally decided dispute. The challenged judgment was sufficiently clear because the dispositive part showed that no cantonal party compensation was ordered, and the missing reference to Art. 68(5) BGG did not create a relevant ambiguity.
