Hello

I would need to know more about the reasons for rejection and whether there is any chance for an administrative or Court appeal.

Nevertheless, based on the topic of this thread, I understand that your relatives´ residence cards´ applications have been rejected due to the fact that they have been out of Spain for more than 12 consecutive months. In this case, there is only a possibility to recover the residency status in the event their cards were related to a Long term residence permit. It is was a temporary one, a new application process will have to be started.

Regards,
