Yes. It would be in the purpose section. And having argued in court—I'm not a lawyer—where the public right to know is considered a quasi-constitutional matter, it's much better to go beyond statutory interpretation and enshrine it right in an act, because it gives the act a lot more clout with individuals who see clearly it's a right, and with the courts who have to interpret the act. Besides, article 2 talks about freedom of expression, and clearly in the modern sense the right to information is part of that.
