The "Principle of Access to Information" (PAI) expressed in the legislation of many countries — usually countries with some "Access to Information Act" or freedom of information laws —, apply to any law document or "obligation rule records", stated by the State. In some countries the obligation of law-publicity and no-payment for information is reinforced by the Ignorantia juris non excusat.
The question here is
How to use PAI for (legally) demonstrate that any other norm or document, citaed by a law document, must be submited also to the PAI?
This situation is similar to the "contamination by use" of a share-alike licenced document (ex. CC by-sa), but here the mechanism is "contamination by citation".
Notes and examples:
This is a question for use with any democratic country where we can start with the hypothesis that “country's law has no copyright”. So, the question is: how to (!?) convince citizens, the government and the court that "any document cited by law also has no copyright"?
Examples where the problem was recognized by court:
coherent use of postcodes: many laws and rules of countries (any, like Brazil, Croatia, Finland, or Uruguay) obligate citizens to use postcodes, and cite explicitly the postcode standards in law. Finland and Uruguay are countries where obligation is coherent with freedom of access (to postcode databases).
Example where the problem (of no oficial answering of this question) exist:
- coherent use of postcodes: ... explanation above... Finland and Uruguay are coherent ... But Brazil and Croatia are not.
In Brazil the postcodes are protected by Authors' rights, but is a country with strong Access to Information Acts, etc. so is possible to create opennes/coherence by using some PAI principle.
