Question juridique clé
Whether the federal criminal appeal had become moot after the cantonal court's acquittal
Solution extraite
Yes. Because the challenged judgment had been superseded by the cantonal court's later acquittal, there was no longer any object to review.
Motifs extraits
The appeal's object fell away once the Kantonsgericht St. Gallen acquitted the defendant; under Art. 32(2) BGG the case had to be removed from the docket as moot.
