Spain’s Supreme Court is considering referring a case concerning the government’s extraordinary immigration regularization process to the European Court of Justice. The court has given all parties involved five days to respond to the possibility of seeking guidance from the EU court. This process, which is nearing its completion deadline of this Tuesday, has already received one million applications. The move suggests a legal challenge to the regularization scheme is gaining traction. The Supreme Court’s decision could potentially suspend or alter the process, impacting the status of many applicants. The core of the dispute centers on the legality of the regularization process under EU law. A ruling is anticipated following the submission of arguments this week.
