R v Secretary of State for the Home Department, ex parte Simms

R v Secretary of State for the Home Department, ex parte Simms [1999] UKHL 33 is a UK constitutional law case, concerning parliamentary sovereignty.
Facts.
Simms and another prisoner, both serving life sentences for murder, brought judicial review proceedings against the Home Secretary’s contention that they could not have oral interviews with journalists unless no part would be published. Under the Prison Act 1952 section 47(1) the Home Secretary had passed Prison Service Standing Order 5, paragraph 37-A which restricted oral interviews with journalists. The prisoners contended this impinged upon the right of journalists to free speech under the European Convention on Human Rights article 10, because practically the opportunity for any investigation into their convictions would be inhibited by not allowing them to speak. The prisoners could, however, engage in written correspondence. 
Latham J held that the prisoners should be able to do oral interviews. The Court of Appeal held the prisoners could not do oral interviews.
