"Belgian justice recognizes our [parliamentary] immunity and decides to suspend the arrest and extradition warrant! @toni_comin", Puigdemont wrote on Twitter.
Puigdemont was elected to the EU legislature in May alongside former Catalan health chief Toni Comin and the region's ex-vice president Oriol Junqueras. However, the politicians have been unable to carry out their mandates since Spain's electoral authorities have not recognised them as members of the European Parliament.
Madrid demanded that Puigdemont and Comin, who have fled to Belgium in the wake of the referendum, take the oath of office in Spain, where they face arrest. Junqueras, in turn, was already in Spanish custody over his role in the referendum when the election results emerged and was unable to engage in the parliament's work.
26 December was the last day for the defence and prosecution to argue their cases in front of the top EU court over whether Junqueras should be given immunity to take up his seat in the Strasbourg-based legislature.
