The Iranian constitution contains many laws which restrict the flow of information. However, these laws are often ambiguous and vaguely worded. This thin legal basis leaves a lot of room for interpretation about what is legal and what is not. Censorship regulation is therefore a highly subjective practice. It depends on the interpretation of the individual bureaucrat in charge whether censorship will be applied or not. These laws can therefore easily be used by government officials who want to suppress dissenting voices. What the Iranian constitution doesn't do is protecting journalists and artists by giving them rights.
