If nobody submits an application as outlined in step 6, DB Netz AG may continue building until there is a decision on the legal challenge ("construction despite existence of action"). If the action is dismissed, the decision becomes final.
If one or more applications are submitted as outlined in step 6, a court assesses them as "urgent applications". DB Netz AG may only start construction once the court dismisses all urgent applications or if building work does not contravene any of them. Construction is suspended if the court rules in favour of an urgent application. If no urgent application is upheld, construction may proceed.
Further information on the planning approval procedure is available in this brochure.
