Suspensive effect is not present in every case. The Federal Office for Immigration and Asylum can withdraw it under the conditions of Section 18 BFA-VG. In that case the measure may be enforceable despite the pending appeal. Whether such a withdrawal was pronounced follows from the operative part and the reasoning of the decision.
If suspensive effect was withdrawn, a separate application is available asking the court to grant suspensive effect. Short deadlines apply, which is why the decision must be examined carefully and quickly. How the deadline for the underlying appeal runs is explained in the entry on the appeal deadline.
In the reasoning the threatened consequences of immediate enforcement count, such as separation from family members. These circumstances are to be set out in the light of Article 8 ECHR.
