Puigdemont and four of his deputies fled to Belgium in October to avoid charges of rebellion, sedition and misusing public money in relation to Catalonia's independence drive, prompting Madrid to seek their return.
But in a surprise move the Spanish Supreme Court withdrew the European arrest warrants last week and today a Belgian judge officially ended the case in Brussels.
Paul Bekaert, Puigdemont's Belgian lawyer, told AFP the judge had declared the case to be "without merit" during a closed-door hearing.
The Catalan officials face arrest if they return to Spain over their role in the independence crisis, which began with an illegal referendum in October, and Puigdemont said last week he plans to stay in Belgium "for now".
He said that if his party wins elections in Catalonia on December 21 then "we should return" but did not give any further details of whether he would actually go back for the polls.
