Question juridique clé
Whether the cantonal court had territorial and subject-matter jurisdiction over the removal order.
Solution extraite
Yes. Jurisdiction lay with Solothurn because the next stopping place after the train intervention was Olten, and the relevant cooperation framework assigned such cases there.
Motifs extraits
The court relied on the Solothurn–Confederation cooperation agreement and the SSK guidance for interventions in moving public transport, which points to the enforced or next exit location.
