The notion of access to information lies between two, somewhat opposite legal concepts:
The protection of personal data;
The access to information.
On the one side, the term refers to the right generally or specifically held by individuals or legal entities to obtain all communicable information under the law or certain items of information that concern them in particular. On the other side, the notion pertains to the right of persons not to have information concerning them be disclosed, modified, or aggregated, especially through any automated processing to which such data may be subject.
OECD countries have passed legislation on the right to access information and established institutions guaranteeing the right to access information. These entities play a fundamental role in the promotion, application, and growth of this right, as well as in the protection of personal data and the communication of documents and information (OECD, 2019).
From an institutional point of view, the oversight functions to guarantee the right to access information and protect personal data may be carried out by a single institution or separately by at least two institutions. Sometimes the functions are performed by an institution that also performs other functions. In organisational terms, there are four kinds of institutions in OECD countries:
An Ombudsman or Mediator (for example, in Sweden, Norway, and New Zealand);
An Information Commissioner (for example, in the United Kingdom, Slovenia, Hungary, Scotland, and Germany);
A commission or institution (for example, in France, Italy, Portugal, Mexico, and Chile);
Another body responsible for monitoring this right, such as the Right to Information Assessment Review Council and the Ombudsman in Turkey, both of which ensure the observance of all relevant laws.
