Article 31
Data and information vital to national defence or security
Nothing in the present Convention obliges a watercourse State to provide data or information vital
to its national defence or security. Nevertheless, that State shall cooperate in good faith with the other
watercourse States with a view to providing as much information as possible under the circumstances.
Article 32
Non-discrimination
Unless the watercourse States concerned have agreed otherwise for the protection of the interests
of persons, natural or juridical, who have suffered or are under a serious threat of suffering significant
transboundary harm as a result of activities related to an international watercourse, a watercourse State
shall not discriminate on the basis of nationality or residence or place where the injury occurred, in
granting to such persons, in accordance with its legal system, access to judicial or other procedures, or a
right to claim compensation or other relief in respect of significant harm caused by such activities
carried on in its territory.
