UN Covenant on civil and political rights

On 28th February 2008 Cuban foreign minister Perez Roque signed the International Covenant on Civil and Political Rights and the International Covenant on Economic, Social and Cultural Rights both of which were introduced in 1976 at the height of the Cold War.

Article 19

1. Everyone shall have the right to hold opinions without interference.

2. Everyone shall have the right to freedom of expression; this right
shall include freedom to seek, receive and impart information and ideas
of all kinds, regardless of frontiers, either orally, in writing or in
print, in the form of art, or through any other media of his choice.

3. The exercise of the rights provided for in paragraph
2 of this article carries with it special duties and responsibilities.
It may therefore be subject to certain restrictions, but these shall
only be such as are provided by law and are necessary:

(a) For respect of the rights or reputations of others;

(b) For the protection of national security or of public order (ordre public), or of public health or morals.
