Zimbabwe has returned the confiscated passports of two government critics.
Mr Ncube was told he was on a list of 64 government critics
Opposition official Paul Themba Nyathi and newspaper owner Trevor Ncube had their passports seized at Bulawayo airport last week.
Both men had begun legal action to recover their passports, but the documents were returned before the matter went to court.
Earlier this year parliament approved a constitutional change allowing the government to confiscate passports.
Mr Themba Nyathi, an official of the opposition Movement for Democratic Change, told the BBC News website he had been told he could collect his passport at the Immigration office in Harare.
"I am sure there is a legal loophole and that is why our passports were returned," he said.
"But knowing this government as I do, I am sure they will find a way to close that loophole and take our passports away again."
Mr Ncube is based in South Africa and owns the Standard and the Zimbabwe Independent newspaper, which have both heavily criticised Mr Mugabe in the past. He also owns South Africa's Mail & Guardian newspaper.
Both Mr Themba Nyathi and Mr Ncube were both told by officials last week they were on a list of 64 people whose passports the government intended to seize.
