When deportation is imminent, many issues are often mentioned at once: return decision, entry ban, risk in the country of return, section 50 FPG and Rule 39 before the ECtHR. In that moment, separation is more important than unstructured speed.
This article does not repeat the general topic of risk in the country of return. It explains the emergency route where irreversible harm under Article 2 or Article 3 ECHR is alleged and an interim measure by the ECtHR may be considered.
Rule 39 does not replace domestic steps. It is relevant only in exceptional situations of imminent serious harm and must be coordinated with available Austrian remedies.
