Lawyers in Macau have raised doubts about how little information has been made available in the case of former lawmaker Au Kam San. The former legislator was sentenced on Friday by the Court of First Instance, known locally as the TJB. He received a single unified prison term of 12 years and six months. The convictions covered crimes against state security and violations of secrecy. The scepticism from the legal community centres on the lack of detail released about the ruling. The source offers no further specifics about what the lawyers want clarified.
