Kernrechtsfrage
Whether the revision request based on later-discovered documents met the statutory revision ground under Art. 123 Abs. 2 lit. a BGG.
Extrahierter Entscheid
The cited documents were neither new nor decisive evidence; the request did not justify reopening the final judgment.
Extrahierte Begründung
The earlier reasons for the applicant's 1987 departure were irrelevant to the 2006 residence-permit review. The alleged facts would not change the legal assessment, and the asserted documents could not alter the consequence of long absence under the former foreigners act.
