<strong>Overlooked</strong>: Surveillance and personal privacy in modern Britain 25<br />

Interception warrants have to be authorised by a Secretary of State, usually the Home Secretary. In<br />

2004 the Home Secretary issued 1849 warrants and a further 674 warrants continued in force from<br />

previous years. By way of comparison, the total number of federal and state wiretap authorisations<br />

in the entire United States in 2005 was 1773. This executive authorisation by a member of the<br />

government rather than a senior judge was a key issue raised by <strong>Liberty</strong> during the course of the<br />

Bill in Parliament and remains the principal sticking point about accountability of RIPA authorisation.<br />

The Government’s argument against judicial authorisation was that authorising interception involves<br />

particularly sensitive decisions that are properly a matter for the executive, and that judges cannot<br />

reasonably be expected to make decisions on what is or is not in the interests of national security.<br />

While the ECtHR has not specifically required that the authorisation be judicial, it has, on several<br />

occasions, stressed the importance of it being so. In Klass v Germany, it said that “it is in principle<br />

desirable to entrust supervisory control to a judge” 44 . Likewise in discussing the safeguards offered<br />

by French law on interceptions, it placed considerable emphasis on the safeguard of prior judicial<br />

authorisation 45 . It is also the practice in a number of countries, including Canada, New Zealand, the<br />

United States and other EU member states.<br />

The Interception of Communications Commissioner, who is a senior judge, provides post-warrant<br />

oversight by reviewing the applications and submitting an annual report to the Prime Minister, which<br />

is laid before Parliament without a confidential annex. In relation to the latter, <strong>Liberty</strong> has long argued<br />

that proper accountability requires greater transparency through the publication of more detailed<br />

annual reports. In countries such as Australia, New Zealand and the US, the law requires publication<br />

of the statistics on the effectiveness of the operations in terms of arrests, prosecutions and<br />

convictions, and their cost. This is relevant to determining the necessity and proportionality<br />

requirements of Art 8 ECHR when deciding on future operations.<br />

Another key debate during the passage of the Bill was whether the historical bar to allowing intercept<br />

evidence to be admissible in criminal trial should remain. <strong>Liberty</strong> has never supported this absolute<br />

bar, which seems to have been founded on concerns for the protection of the security services’<br />

sources and methods rather the fairness of the trial process. The bar is a legal anomaly as the UK is<br />

virtually the only country to have such a ban 46 . Whilst the evidence obtained under domestic<br />

intercepts is inadmissible, that obtained under foreign intercepts can be used if this is in accordance<br />

with foreign laws. There are no fundamental civil liberty or human rights objections to the use of this<br />

material, properly authorised by judicial warrant, in criminal proceedings. Rules of criminal evidence<br />

will apply to ensure that evidence is not admitted in such a way as to unfairly prejudice the case. And<br />

if there are concerns over protection of the state’s sources, then clearly established rules of evidence<br />

may be used, to allow disclosure to be withheld from the defence and public.<br />

More recently, this debate has focused on the evidential difficulties in terrorism cases and the fact<br />

that some of the exceptional counter-terrorism measures – including that of control orders – are<br />

being justified on the grounds that obtaining sufficient admissible evidence to prosecute in terrorism<br />

Huvig v France (1990) at para.33: “The court does not in any way minimise the value of several of the<br />

safeguards, in particular the need for a decision by an investigating judge, who is an independent judicial<br />

authority…”.<br />

The Republic of Ireland being the only other state in the European Union to have a similar bar.
