Key legal question
Whether the Federal Tribunal judgment 2C_20/2013 had to be interpreted or corrected under Art. 129 LTF.
Extracted holding
No. The operative part was clear; the request merely sought a substantive reconsideration and was therefore inadmissible as an interpretation/correction request.
Extracted reasoning
Interpretation under Art. 129 LTF is limited to unclear, incomplete, ambiguous or contradictory dispositive parts, or clerical/calculation errors. The applicant identified no such defect and instead attempted to obtain a new review of the merits.
