公众信息获取权被视为信息社会公民的重要权利,从宪法的维度上来说,公众信息获取权来源于知情权这一宪法基本权利。从美、日、德等国的学说和判例来看,知情权虽然并未被普遍写入宪法,但可以从已有的基本权利中找到源头。信息社会时代下的公众信息获取权,兼具自由权和社会权的特征,不仅排除国家权力对信息获取的干涉,同时要求国家为保障公民的信息获取,采取积极作为,保障公民的人格发展与民主权利。 The right to obtain public information is regarded as an important right of citizens in information society. From the perspective of constitution, the right to obtain public information comes from the fundamental right of knowing the constitution.
