The Law Society of Zimbabwe, representing over 600 practising legal practitioners, brought a constitutional challenge under section 24 of the Constitution of Zimbabwe against sections 98(2) and 103 of the Postal and Telecommunications Act [Chapter 12:05]. The applicant contended that these provisions threatened its members' right to freedom of expression as enshrined in section 20 of the Constitution. The impugned sections conferred on the President powers to intercept and detain postal articles, telegrams, and communications transmitted by telecommunications services if, in the President's opinion, it was necessary in the interests of national security or maintenance of law and order. The applicant argued that these provisions posed a threat to lawyer-client privilege, which is protected by common law and section 8 of the Civil Evidence Act, and that legal practitioners must be able to receive confidential communications from clients without interference. The respondents conceded that the sections derogated from freedom of expression but argued they fell within permissible constitutional exceptions and were reasonably justifiable in a democratic society.
The application succeeded. Sections 98(2) and 103 of the Postal and Telecommunications Act [Chapter 12:05] were declared unconstitutional and struck down. The respondents were ordered to pay the costs of the application jointly and severally, the one paying the other to be absolved.
Legislative provisions that confer powers to intercept correspondence and communications must contain adequate safeguards, limitations and accountability mechanisms to be reasonably justifiable in a democratic society under section 20(2) of the Constitution. Provisions that grant unfettered discretion based solely on subjective opinion without requiring reasonable grounds, and which lack mechanisms for independent supervision, prior scrutiny, protection of privileged communications, accountability, or remedies for abuse, are too broad and vague to satisfy the constitutional requirement of being 'provided by law' and are not reasonably justifiable in a democratic society. Such provisions are unconstitutional even in the absence of evidence of actual abuse. Laws limiting fundamental rights must be sufficiently certain to enable citizens to regulate their conduct accordingly.
The Court observed that lawyer-client privilege, while of fundamental importance to the administration of justice and beneficial to all sectors of society including the State, is not absolute. The privilege has recognised exceptions including: (a) the right of the accused to fully defend themselves; (b) communications that are criminal in themselves or intended to obtain legal advice to facilitate criminal activities; and (c) when public safety is at risk. The Court noted that while lawyer-client privilege is not expressly guaranteed by the Constitution as such, it is constitutionally protected to the extent that it is subsumed within the right to freedom of expression (including freedom from interference with correspondence) under section 20. The Court also observed that breach of lawyer-client privilege almost invariably leads to violation of the right to a fair trial guaranteed under section 18 of the Constitution, though this was not the basis of the present application. The Court referenced similar legislation in other jurisdictions that provides for prior scrutiny, independent supervision and effective remedies.
This case is significant in Zimbabwean constitutional jurisprudence as it establishes important principles regarding the protection of fundamental rights, particularly freedom of expression and correspondence. It affirms that state powers to intercept communications must be exercised within clear legal frameworks with appropriate safeguards, accountability mechanisms, and independent oversight to be constitutionally valid. The judgment reinforces the importance of lawyer-client privilege as integral to the administration of justice and the right to a fair trial. It establishes that laws derogating from constitutional rights must be sufficiently certain (satisfying the 'provided by law' test), must not confer unfettered discretion, and must be reasonably justifiable in a democratic society. The case demonstrates the judiciary's role in scrutinising executive powers and striking down legislation that fails to provide adequate safeguards against abuse, even when there is no evidence of actual abuse. It sets standards for surveillance and interception legislation requiring mechanisms for prior scrutiny, independent supervision, and effective remedies.
