Carles Puigdemont, the former leader of Catalonia, made a renewed call on Saturday for Spanish authorities to open negotiations over the region’s secession claim, a day after he was released from a German jail.

Mr. Puigdemont told reporters that he hoped a German court’s decision not to extradite him to Spain on charges of rebellion showed that “that political measures are needed” to defuse the political conflict in his home country.

“This opens a new opportunity of dialogue,” Mr. Puigdemont said at a news conference in Berlin.

Justice Minister Katarina Barley of Germany applauded the court’s decision to free Mr. Puigdemont on bail as “absolutely right” and what she had expected.

She said that if Spain could not prove the allegations of misuse of public funds, “then Puigdemont will be a free man in a free country — namely in Germany.”

The former president of Catalonia left a German prison in Neumuenster on bail on Friday, almost two weeks after his arrest, after a state court in Germany decided the charge of rebellion did not warrant extradition because the accusation is not punishable under German law. Mr. Puigdemont can still be extradited on the less serious charge of misuse of funds to hold Catalonia’s banned independence referendum last year.

After Catalonia declared independence last fall, Spain’s central government dissolved the regional Parliament and charged its leaders with sedition, a move which prompted Mr. Puigdemont to flee into exile in Brussels. He was returning to Belgium from a conference in Finland when he was detained by German authorities on March 25 on a European arrest warrant issued by Madrid.

Misuse of public funds carries a sentence of up to eight years in Spain, while a rebellion sentence can reach 30 years.

Prime Minister Mariano Rajoy of Spain, speaking in the southern Spanish city of Seville, said his government respects the decision by the German court.

Mr. Puigdemont, 55, told reporters he would stay in Berlin until his extradition case is concluded. If he is not sent back to Spain, he said he would plan to return to Belgium where he has established residency.

Catalonia remains in a political deadlock more than five months after Mr. Rajoy ousted Mr. Puigdemont’s administration and placed the region under direct rule from Madrid. Separatist lawmakers have not been able to form a new administration after winning a narrow parliamentary majority in an election in December called by Mr. Rajoy.
