"This paper identifies four primary drivers of proactive disclosure throughout history. The first is the need to inform the public about laws and decisions and the public’s right to be informed, to know their rights and obligations. The second is the public’s demand for the information needed to hold governments accountable both at and between elections. The third is the demand for information in order to participate actively in decision-making. The fourth is the provision to the public of information needed to access government services, which has expanded significantly in the past decade with growth of electronic access to services or “egovernment.” [...] The recently adopted legal frameworks which include proactive disclosure regimes (Section 3) point to an emerging standard on the classes of information which should be made available at the core of any national proactive disclosure regime. The national standards are reiterated and complemented by provisions by international international bodies (Section 4). These international provisions make clear that, in addition to having numerous benefits for public bodies and for members of the public, proactive disclosure is an obligation that is part of the right of access to information. From comparing the national and international provisions it is possible to identify a set of 14 core-minimum of classes of information for proactive disclosure." (Executive summary, page 1)
