Article 6U.K.Return decision
1.Member States shall issue a return decision to any third-country national staying illegally on their territory, without prejudice to the exceptions referred to in paragraphs 2 to 5.
2.Third-country nationals staying illegally on the territory of a Member State and holding a valid residence permit or other authorisation offering a right to stay issued by another Member State shall be required to go to the territory of that other Member State immediately. In the event of non-compliance by the third-country national concerned with this requirement, or where the third-country national’s immediate departure is required for reasons of public policy or national security, paragraph 1 shall apply.
3.Member States may refrain from issuing a return decision to a third-country national staying illegally on their territory if the third-country national concerned is taken back by another Member State under bilateral agreements or arrangements existing on the date of entry into force of this Directive. In such a case the Member State which has taken back the third-country national concerned shall apply paragraph 1.
4.Member States may at any moment decide to grant an autonomous residence permit or other authorisation offering a right to stay for compassionate, humanitarian or other reasons to a third-country national staying illegally on their territory. In that event no return decision shall be issued. Where a return decision has already been issued, it shall be withdrawn or suspended for the duration of validity of the residence permit or other authorisation offering a right to stay.
5.If a third-country national staying illegally on the territory of a Member State is the subject of a pending procedure for renewing his or her residence permit or other authorisation offering a right to stay, that Member State shall consider refraining from issuing a return decision, until the pending procedure is finished, without prejudice to paragraph 6.
6.This Directive shall not prevent Member States from adopting a decision on the ending of a legal stay together with a return decision and/or a decision on a removal and/or entry ban in a single administrative or judicial decision or act as provided for in their national legislation, without prejudice to the procedural safeguards available under Chapter III and under other relevant provisions of Community and national law.
